==Summary==


The Goa'uld are aquatic parasitic creatures which evolved into intelligent, but extremely evil, beings. A symbiote, as it is also known as, invades a host, usually human, through the back of the neck (some have been known to go through the front) and blends into the host's biological structure, attaching itself into the brain and thus gaining access to the host's knowledge and voluntary muscular system. The term "Goa'uld" is applied to both the symbiote itself and the blended host, since the host of a Goa'uld is prevented from exerting his own personality after the blending.  
The Goa'uld are aquatic parasitic creatures that evolved into intelligent, but extremely evil, beings. A symbiote, as it is also known as, invades a host, usually human, through the back of the neck (some have been known to go through the front) and blends into the host's biological structure, attaching itself into the brain and thus gaining access to the host's knowledge and voluntary muscular system. The term "Goa'uld" is applied to both the symbiote itself and the blended host, since the host of a Goa'uld is prevented from exerting his own personality after the blending.  


This article concentrates on the Goa'uld personalities, rather than on the symbiotes (covered in another article). To find out more information about each Goa'uld mentioned herein, use the links at the end of this article to read their more detailed biographical articles.
The Goa'uld have existed for a very long time, but they have been most successful in exerting their power since they took humans as hosts (their first hosts, the Unas, evolved on the same planet, P3X-888). The First World, Earth, was found by the Goa'uld Ra 10,000 years ago. He was searching for a new type of host for his dying race. He found that the human body made a very good host and was easily maintained through the use of the sarcophagus, a device capable of rapid healing, even from death.
Since Ra's visit to Earth, the Goa'uld have favored human beings as hosts and have taken groups of people from Earth to other planets suitable for them. They found the network of Stargates left behind by the Ancients to be a most useful tool, since the planets on which these Stargates were found were very Earth-like and would make perfect human-sustaining environments. The Goa'uld would visit these planets and take the most beautiful and healthy people to become new hosts. Teal'c described the visits as "harvests", to which Daniel replied, "You know, I wish you wouldn't say 'harvest'. We're talking about human beings, not brussel sprouts." Teal'c's responded to this by saying, "That is how the Goa'uld perceive it."


==Stargate References==
The Goa'uld perceive humans as "brussel sprouts" because they have genetic memory that gives them great knowledge. With each generation, however, access to this extraordinary knowledge produced a "god complex" and they became increasingly evil. To ensure their supremacy, they scavanged the galaxy for the latest technological advances. If a world began to show technological progress, the Goa'uld destroyed it or took it over and forced the inhabitants into slavery. Usually, this slavery included mining the precious mineral naquadah on which much of the Goa'uld's technology depended. When the mines ran dry, the Goa'uld usually abandoned the planets, leaving the people to fend for themselves. In some cases, the people were successful in overthrowing their oppressors and buried the Stargate to prevent the Goa'uld's return. The burying of the Stargate, however, did not always guarantee that the world would be free from the Goa'uld threat indefinitely, since the Goa'uld possessed starships capable of traveling exceedingly fast through hyperspace windows.


===Stargate - The Movie===
In the process of building their power, the Goa'uld made allies and enemies. As far as allies go, however, any arrangements made between the Goa'uld were usually short-lived and only lasted as long as a specific purpose was served, this purpose most often being to maintain the balance of power.


We learn of the parasitic nature of the Goa'uld when Daniel Jackson interpreted the pictorial story drawn on a wall in the old part of a temple on Abydos on his first mission there. This story told of how an alien being searched for a new host for his dying race and found the humans of Earth to be most suitable. This alien stole the identity of the god Ra of the ancient Egyptians of 10,000 years ago, forcing the ancient Egyptians into servitude. The young boy whom Ra took as a host remained his host for all of those thousands of years, his body sustained by the symbiote itself and the technology of the sarcophagus.  
Since opening the Stargate on Earth, Stargate Command (SGC) was plunged into the middle of the galactic power struggle. Their first trip through the Stargate sent them to Abydos, a planet peopled by the descendants of Ancient Egyptians. The Abydonians slaved in the naquadah mines and worshipped Ra as their god for thousands of years. Col. Jack O'Neill and Dr. Daniel Jackson helped free the people by destroying Ra and his starship in orbit. Ra was the most powerful and feared of all the Goa'uld System Lords. After his death, the balance of power was forever changed and, subsequently, those who had hoped to overthrow the Goa'uld were given a fighting chance.


[[Image:ra1.jpg|thumb|170px|none|[[Ra]]]]
The struggle for the balance of power among the System Lords lasted nine years (since the death of Ra), until only the System Lord Ba'al remained of any great significance. His role, however, was reduced greatly when the Rebel Jaffa convinced the remaining Jaffa armies that the Goa'uld were not gods and they took the temple on the planet Dakara that was deep in Ba'al's territory. Ba'al lost his army, his territory, and his ships in the final battle among the Goa'uld, Rebel Jaffa, Tau'ri, Tok'ra, and Replicators over the planet Dakara.  


Daniel Jackson educated the Abydonians on the nature of their "god" and, as a result, they revolted, just as the people of Ancient Egypt had when they buried the stargate on Earth. Colonel Jack O'Neill and Daniel killed Ra with the bomb originally intended to destroy the Abydos stargate. As a result, the people of Abydos were freed and became Earth's first ally in the fight against the Goa'uld.
Although not all of the Goa'uld are dead, the great power that they enjoyed for thousands of years no longer remains.


===Seasons One Through Three===
==Comprehensive History of the Goa'uld==
{{Goa'uld Articles}}


The next Goa'uld we encounter is Apophis, in the pilot, "Children of the Gods":
==Alliances==


[[Image:apophis.jpg|thumb|170px|none|[[Apophis]]]]
It is in the nature of the Goa'uld to serve only their own interests and basically operate on their own. However, within the race, there were some alliances formed when one group of Goa'uld wished to overthrow another.


Apophis came through the thought to be inactive stargate on Earth and captured a female sergeant. A violent battle was fought in the embarkation room, and casualties were suffered on both sides. The SGC learned about the nature of the Jaffa by examining the remains of one of Apophis' warriors.
===System Lords===


They decided to return to Abydos and retrieve Dr. Daniel Jackson. Not long after they arrived, Apophis attacked Abydos and took Daniel's wife, Sha're, and her brother, Skaara, as prisoners. Major Ferretti saw the coordinates of the address to which Apophis escaped, so the SGC sent two teams after them.
The Goa'uld formed a feudal system of galactic rule in which the most powerful were known as System Lords. These System Lords created a High Council that exerted itself whenever one of their own began to gain too much power. The High Council was also a means by which the System Lords could unite to defeat a common enemy. They took votes on requests for a seat on the Council, but this vote did not have to be unanimous (5.16 "Last Stand Part 2"). They also required a fully-assembled Council in order to vote to stop any action they had originally agreed upon (8.02 "New Order Part 2"). The number of members of the High Council varied as System Lords came and went, but the latest estimate the SGC had indicated that the Council had around a dozen members (8.01 "New Order Part 1"). The last of the High Council died at the hands of the Replicators (8.16 "Reckoning Part 1").
* When the System Lords saw the humans of Earth, called the Tau'ri, as a threat after SG-1 eliminated several of their most powerful within a very short period of time, their attention was directed toward Earth as a possible planet for conquest or destruction. The Asgard found out about this and decided to add Earth to their list of protected planets in the Protected Planets Treaty they had with the Goa'uld System Lords. In this agreement, the Goa'uld promised that they would not destroy Earth because they feared the Asgard's supreme weaponry. Three System Lords came to Earth to represent the interest of the High Council and to negotiate with Thor of the Asgard. (3.03 "Fair Game")
* The System Lords called a summit of the High Council after the defeats of Cronus and Apophis, both of which SG-1 had helped accomplish (4.21 "Double Jeopardy" and 5.01 "Enemies Part 2", respectively). The seven most powerful System Lords met in this summit to create a new order because they had created too many losses among their own power bases fighting amongst themselves in their attempt to gain the control of the vacated domains of the two former System Lords. They also needed to deal with a common enemy, Anubis, who had once been among them but had been banished for crimes that were unspeakable even for the Goa'uld. Anubis was quickly gaining power and the High Council decided to permit him to rejoin them as a fellow-System Lord rather than fight him as an enemy. Before he took his position on the High Council, Anubis promised to get rid of the Tok'ra and the Tau'ri since he wasn't bound by the Protected Planets Treaty. (5.15 "Summit Part 1" and 5.16 "Last Stand Part 2")
* Anubis failed in annihilating the Tok'ra and the Tau'ri and most likely never gained his seat back on the Council, even though he had been voted back in. When he was collecting weapons enhancement technology, called Eyes, to create a powerful superweapon on his mothership, the System Lords, led by Yu who had opposed his readmission, attacked Anubis in orbit over Abydos. The System Lords were not able to defeat him and after losing several ships, they retreated. Anubis destroyed Abydos as a demonstration of his power and as a reminder to SG-1 not to challenge his position again, since it had been Daniel, as an Ascended Being, and SG-1 who had attempted to protect Abydos and prevent his rise in power. (6.22 "Full Circle")
* The SGC involved the High Council of the System Lords once again in opposing Anubis by baiting him with the possible location of the Lost City of the Ancients that was supposed to have a powerful weapons cache that would guarantee the possessor of galactic supremacy. The System Lords, under the leadership of Yu, was supposed to assemble over the planet Vis Uban after the SGC eliminated his superweapon. But, because Lord Yu was showing senility, his First Prime Oshu asked that Ba'al lead the combined fleet against Anubis. Ba'al did this and Anubis' mothership was destroyed in the skies of Kelowna (Jonas Quinn's homeworld), but Anubis escaped. (7.01 "Fallen Part 1" and 7.02 "Homecoming Part 2")
* After Anubis was defeated through the use of the powerful weapon left behind by the Ancients on Earth in their Antarctic Outpost, the System Lords sent three representatives to Earth to discuss regaining the balance of power by eliminating Ba'al who had been taking more than his fair share of Anubis' domain. As a test of Earth's strength and that of the Asgard, the System Lords sent a ship to provoke Earth into using the Ancient weapon, but Ba'al destroyed the ship before it made it to Earth. The System Lords did not get their demonstration of the weapon and were sent home to continue their struggle against Ba'al. (8.01 "New Order Part 1" and 8.02 "New Order Part 2")
* Ba'al's rise in power meant that many of the System Lords either died or capitulated. Eventually, only three System Lords remained: Lord Yu and two others. They were massacred on their summit space station by Replicator Carter, so that only Ba'al remained in power. (8.16 "Reckoning Part 1")
* Ba'al's total dominance, however, was kept in check by Anubis, who had himself regained much of his power after his defeat over Antarctica. These two System Lords joined forces in order to defeat the Replicators and the Rebel Jaffa, but they suffered a major blow with the destruction of their fleets in orbit over the planet Dakara, located deep within Ba'al's territory. Ba'al assisted the Tau'ri and Tok'ra in destroying the Replicators using the weapon left behind by the Ancients on Dakara, and Anubis discovered his betrayal and promised he'd live only to see the entire galaxy destroyed. Anubis was stopped in remaking the galaxy in his "grand design" by Oma Desala who engaged him in an eternal battle on the ascended plane. Ba'al remained, but his fleets, territory, and armies were no longer his. The System Lords are now no longer. (8.17 "Reckoning Part 2", 8.18 "Threads")


When they arrive on the planet, later known as Chulak, SG-1, consisting of Col. Jack O'Neill, Daniel Jackson, and Capt. Samantha Carter, were captured. We learn that "Goa'uld" is an ancient Egyptian, Abydonian, or Chulakan term meaning "gods" when Skaara translated Apophis' First Prime Teal'c's announcement that some of the prisoners were to become hosts for the "children of the gods".
===Linvris===


Fortunately, Teal'c realized that the humans of Earth had known freedom from enslavement to the Goa'uld and he decided to defy orders and save them and the rest of the prisoners. They made their escape and Teal'c was eventually accepted as the fourth member of SG-1.
The Linvris was a group of nine Goa'uld who opposed the System Lords. They never gained much power and were killed by inventions left behind by Ma'chello, a man who had been placed on top of the System Lords' most wanted list because he had become a major threat to their existence. (3.04 "Legacy")


We met three more Goa'uld in this mission: Amaunet, Apophis' queen who took Sha're as a host; Klorel, Apophis' son who took Skaara as a host; and an unnamed Goa'uld who took Major Charles Kawalsky as a host:
==Enemies==
{|

|valign="top"|[[Image:klorel.jpg|thumb|170px|left|[[Klorel]]]]
|valign="top"|[[Image:kawalsky-goauld.jpg|thumb|170px|left|[[Charles Kawalsky|Kawalsky's Goa'uld]]]]
|}
The Goa'uld which had taken Kawalsky on Chulak was able to trick the SGC's surgeon, Dr. Warner, into believing that he had successfully extracted the symbtiote from Kawalsky. Unfortunately, in order to prevent the Goa'uld from killing more SGC personnel and escaping through the stargate, Kawalsky was killed (1.03 "The Enemy Within").


Apophis, Klorel and Amaunet escaped from Chulak.
===Asgard===


SG-1 later met up with Apophis on the planet of the Nox (1.08 "The Nox"), but Apophis was removed from the planet before he could be captured for information leading to Sha're and Skaara.  
The Asgard had a Protected Planets Treaty signed with the System Lords that attempted to keep the Goa'uld in check. The terms of this treaty were not revealed in great detail and it seemed to be absolutely worthless once the System Lords gained more advanced technology to overpower even the Asgard. After the defeat of the System Lords and Replicators, the Asgard withdrew for a time to address their cloning issues. After realizing that their generations upon generations of extending their lives through cloning had produced a rapidly degenerating disease, the Asgard decided to end their lives in an act of mass suicide. They gave Earth all of their knowledge and advanced technology before their homeworld Orilla exploded during an attack by the Ori. They destroyed their world to prevent their advancements from falling into enemy hands (10.20 "Unending").
* The Asgard added Earth to the Protected Planets Treaty (3.02 "Fair Game"). This agreement did not bind the Goa'uld who were not part of the High Council and stated that the Asgard could not use their technology to save a protected planet if it was threatened by natural causes. These two points were used against Earth when Anubis attempted to destroy Earth by sending a naquadah-rich asteroid on a collision course (5.17 "Failsafe") and sending a build-up of energy through the Stargate (6.01 "Redemption Part 1" and 6.02 "Redemption Part 2").
* While attempting to protect a planet that had a valuable Asgard genetic research facility, Thor's ship was destroyed and he was taken prisoner by Osiris and Anubis. Neither one of these Goa'uld were bound by the Treaty, evidently. Anubis used a mind probe on Thor that gave him access to all of the Asgard's technological and strategic knowledge and, with this knowledge, Anubis became the most powerful Goa'uld System Lord. (5.22 "Revelations")
* Anubis attempted to destroy Earth a third time by sending an attack fleet composed of over thirty vessels. SG-1 found a powerful weapon built by the Ancients in an outpost they had in Antarctica. After Anubis' destruction, the System Lords sent three of their representatives to Earth to ask for help in destroying Ba'al who was greedily taking more than his fair share of Anubis' domain. These representatives stated that Ba'al intended to go after the planets of the Protected Planets Treaty (27 planets, including Earth) because he believed that the Asgard no longer exercised power in the galaxy. (8.01 "New Order Part 1")


In the episode, 1.13 "Fire And Water", SG-1 went to a planet, later called Oannes, where they believed that they witnessed Daniel Jackson being killed by fire. This incident was actually a false memory implanted by the Being of Oannes named Nem, who realized that Daniel knew about Babylon and recognized cuneiform writing. Nem was searching for the fate of his mate, Omoroca, and he felt that Daniel knew what it was. As it turns out, Omoroca had visited Earth during the Babylonian empire and attempted to keep the Goa'uld named Belus from enslaving the humans. Belus killed Omoroca, but Daniel assured Nem that her death was not in vain because the people of Egypt did revolt against the false gods and Earth was free. Nem let Daniel return to Earth to continue his search for his mate, Sha're. We later hear of the Goa'uld Marduk in Season Five and it is possible that this Marduk was the same Goa'uld as Belus.
===Giant Aliens===


The next Goa'uld encountered by the SGC was Hathor:
The Giant Aliens are associated with Toltec and Aztec mythology and it was Nicholas Ballard, Daniel's grandfather, who had discovered them back in the 1970's when he came across a crystal skull in a temple in Belize that transported him to the aliens' planet. SG-1 happened upon this same planet and eventually, reunited Nick with his "Giant Aliens". The aliens invited Nick to stay with them so that they could exchange culture and knowledge, after Daniel answered the riddle, "The enemy of my enemy is my friend," by stating that the Goa'uld were their enemies as well. The history of why the Goa'uld and the Giant Aliens were enemies was not revealed. (3.21 "Crystal Skull")


[[Image:hathor.jpg|thumb|170px|none|[[Hathor]]]]
===Ma'chello===


Hathor had been in stasis in her sarcophagus in a Mayan temple and she was released when the archaeologists came upon her there. She was able to make it to Colorodo, sensing the stargate. Hathor attempted to take over Earth by drugging the men into submission and subjugating the women, but the plan backfired when Captain Samantha Carter and Dr. Janet Fraiser were able to lead a team of women to overcome their aggressor. Hathor was able to escape through the stargate to Chulak. Although extremely attractive, Hathor proved to be one of the most dangerous and evil of all of the Goa'uld. She raped Daniel Jackson for his DNA in order to make her subsequently-spawned Goa'uld larvae compatible with their future human hosts, and she attempted to transform Colonel Jack O'Neill into a Jaffa (1.14 "Hathor"). Hathor later captured Jack, Daniel, and Carter, and left Teal'c for dead, in order to obtain up-to-date information on the power structure of the Goa'uld. Jack killed her (2.22 "Out Of Mind Part 1" and 3.01 "Into The Fire Part 2").
Ma'chello's life was dedicated in eliminating the Goa'uld by inventing various weapons against them. The Goa'uld took his wife as a host and attempted to have him taken as well in order to preserve his knowledge. He escaped before being implanted. He died in the SGC infirmary, but he left behind many of his Goa'uld-killing inventions as if placing carefully-concealed mine fields. (2.18 "Holiday" and 3.04 "Legacy")


Even though the Goa'uld Nirrti is mentioned in the episode, 1.15 "Singularity", the SGC does not meet her face-to-face until a little later. It was discovered that Nirrti killed an entire population of the planet Hanka and all the members of SG-7, sparing only one little girl named Cassandra. Nirrti planted a bomb within Cassandra's heart to go off when she got near the naquadah of the stargate. It was intended that Cassandra be a Trojan Horse for Earth's destruction, but the SGC was able to discover the plan and thwart it.
===Rebel Jaffa===


Apophis led an attack on earth with Klorel at his side in the episodes, 1.22 "Within The Serpent's Grasp" and 2.01 "The Serpent's Lair Part 2", and even though SG-1 was successful at destroying their two motherships, Apophis and Klorel were able to escape. With the destruction of these two ships, Apophis' position was weakened and he attempted to improve himself by producing a new host. This new host was the human offspring of the host of Apophis and Sha're, but inherited the genetic memory of the Goa'uld. Such a child is called a Harsesis. Apophis sent his queen, Amaunet, to Sha're's homeworld Abydos to hide her there from the other System Lords who would hunt the child down and kill him. Daniel and Teal'c encountered Sha're on the planet and Daniel delivered the child with his own hands. Teal'c was successful at fooling Amaunet into thinking that the child was taken by Heru'ur, a known enemy of Apophis, but Daniel was able to give the child to Sha're's father, Kasuf, for safe-keeping in the episode, 2.09 "Secrets".  
The movement of the Jaffa to end the tyranny of the Goa'uld was started by Teal'c, and their numbers began to grow once he made the call to fight against the false gods (3.01 "Into The Fire Part 2"). The Jaffa were genetically-altered humans of Earth who were engineered to carry the Goa'uld symbiotes to maturity in an abdominal pouch to improve the symbiote's chances of successfully blending with a host (1.03 "The Enemy Within"). Without the Jaffa, a symbiote had a one-in-two chance of success (6.10 "Cure"). The Jaffa's entire immune system depended on the symbiote's natural healing capabilities. The symbiotes gave the Jaffa long lives and good health, but the Jaffa depended on the symbiotes for their very survival. The Goa'uld used the strong Jaffa as soldiers and the others served them in their temples. Teal'c knew that the Goa'uld were not gods, as the Jaffa were taught since birth, but parasites. The Rebel Jaffa who answered his call built their numbers and hoped one day to free all of their brethren. At one time, they took sanctuary at the SGC's Alpha Site (6.09 "Allegiance"), but decided to strike out on their own after the Alpha Site had been discovered by Anubis and destroyed (7.16 "Death Knell"). It was most likely because of the Rebel Jaffa that Anubis replaced his Jaffa with the genetically-engineered Kull Warriors (7.11 "Evolution Part 1" and 7.12 "Evolution Part 2"). Ultimately, in the fateful encounter over the skies of the planet Dakara, the Jaffa won their freedom when the Goa'uld System Lords Ba'al and Anubis were defeated and the remaining army of Kull Warriors were destroyed (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads"). The struggle to form a strong, independent nation began at the same place where the Jaffa were created by the Goa'uld — on Dakara (8.18 "Threads"). After the Ori destroyed Dakara, the Free Jaffa Nation splintered as they struggled for their own survival (10.07 "Counterstrike").  


[[Image:heruur.jpg|thumb|170px|none|[[Heru'ur]]]]
===Reetou===


An interesting twist in the Goa'uld story was the revealing of a same-specie enemy called the Tok'ra. The first Tok'ra met by the SGC, Jolinar of Malkshur, took Captain Samantha Carter as its new host at the moment its host died while Carter was giving him mouth-to-mouth resuscitation. Jolinar was attempting to evade a Goa'uld assassin, called an Ashrak, by taking different hosts and not revealing its presence. An Ashrak is a Goa'uld who has been specifically trained as an assassin and hired by the System Lords (2.01 "In The Line Of Duty"):
The Reetou are an insect-like alien species that are 180 degrees out of phase with the humans of Earth, so they are invisible to the naked eye. The Goa'uld attempted to destroy the Reetou and as a result, Reetou rebel forces believed that the only way to get rid of the Goa'uld was to eliminate all possible hosts. It was this extreme reasoning that led this group of Reetou to attempt to destroy Earth. (2.20 "Show and Tell")


[[Image:ashrak1.jpg|thumb|170px|none|[[Ashrak]]]]
===Replicators===


This particular Ashrak was killed in the embarkation room after he had attacked Carter/Jolinar and left them for dead. It was later revealed in the episode, 3.03 "Fair Game", that it was Cronus who had sent this Ashrak after Jolinar.
The Replicators were everyone's enemy because they didn't play political games at all—they just consumed everything they could to reproduce and this included the advanced technology that the Goa'uld possessed. The Replicators were primarily the enemy of the Asgard, but they were instrumental in the spectacular demise of Apophis before they evolved into human form (5.01 "Enemies Part 2"). Replicator Samantha Carter led the Replicators against the Goa'uld and nearly destroyed them, but she and all of her "brethren" were destroyed through the joint effort among the Goa'uld, Rebel Jaffa, Tau'ri, and Tok'ra (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2").  


Apophis turned up again in SG-1's lives by calling them to his rescue in his escape attempt from Sokar, in the episode, 2.17 "Serpent's Song". Sokar had captured Apophis and was taking great delight in torturing him. The SGC took Apophis in when he asked for asylum, but after both the symbiote and host died, they sent him back through the stargate to Sokar because Sokar was attacking Earth with harmful radiation though the stargate in successive 38-minute intervals. The SGC was able to dial out between one of these attacks to send the body through and Sokar's attacks stopped. Viewers are not given the privilege of seeing Sokar's face until the episodes, 3.12 "Jolinar's Memories Part 1" and 3.13 "The Devil You Know Part 2":
===Tau'ri===


[[Image:sokar.jpg|thumb|170px|none|[[Sokar]]]]
The Tau'ri, humans of the First World (Earth), became an enemy of the Goa'uld as soon as Ra landed his spaceship in Eygpt seeking a new kind of host for his dying race in 8000 B.C. Like Ra, many of the Goa'uld who took the humans as hosts took on the identity of other gods of Earth, including those from Babylonian, Canaanite, Celtic, Chinese, Egyptian, Greek, Hindu, Japanese, and Roman mythologies (the word "Goa'uld" means "god"). Since the Tau'ri reopened the Stargate on Earth and organized Stargate Command (SGC), they gave the Goa'uld reason to seriously consider that their days were numbered as the most powerful force in the galaxy. The Goa'uld System Lords were finally defeated after eight years of war, and they no longer posed the threat that they once did for thousands of years (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads", 8.19 "Moebius Part 1").


Sokar was killed when the ship he was on was destroyed. This allowed Apophis, who had been revived in a sarcophagus after the SGC sent his body back and had been a slave to Sokar, to take Sokar's domain and thrust himself into great power once more.
===Tok'ra===


The Reetou were introduced in the episode, 2.20 "Show And Tell". They are an alien species which are 180 degrees out of phase with the humans of Earth, so they are invisible to the naked eye. The Reetou are enemies of the Goa'uld and there was a rebel force of them which believed that the only way to get rid of the Goa'uld was to eliminate all possible hosts. It was this extreme reasoning that led this group of Reetou to attempt to destroy Earth.
The Tok'ra were started over 2000 years ago by the Goa'uld Egeria who first opposed Ra (Tok'ra means ''against Ra'') and his enslaving of the humans he took through the Stargate (4.04 "Crossroads"). All the Tok'ra are descendants of Egeria and, therefore, inherited her Goa'uld genetic memory and her desire to have a truly symbiotic relationship with the host. The Tok'ra do not use the sarcophagus, but instead, take new hosts when the host is about to die (most human hosts of the Tok'ra live to be close to 200 years old). They worked against the Goa'uld through subterfuge. Because they are of the same race as the Goa'uld, there was no way for the Goa'uld to tell the difference between one of their own and a Tok'ra, and the Tok'ra used this to their advantage by infiltrating the ranks of the System Lords and assuming the role of a minor Goa'uld in the System Lord's service. (2.11 "The Tok'ra Part 1" and 2.12 "The Tok'ra Part 2") The Tok'ra moved their underground bases of operations continuously, but, at one point, they took residence at the SGC's Alpha Site (6.09 "Allegiance"). Their stay on the Alpha Site was short because they were at a greater risk of being discovered with both the Tau'ri and Rebel Jaffa living there. Because of their dwindling numbers (Egeria was banished thousands of years ago and did not produce any more Tok'ra offspring), they decided to return to their underground bases (7.16 "Death Knell"). Egeria was discovered in stasis on one of Ra's former planets and died soon thereafter, basically guaranteeing the end of the Tok'ra once the last one dies (6.10 "Cure"). Despite this, the Tok'ra continued to oppose the Goa'uld and fought for the freedom of their slaves, human and Jaffa alike (6.19 "Changeling"). The Tok'ra lived to see the defeat of the Goa'uld System Lords (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads"), but their lives are close to an end because they do not use a sarcophagus to extend their lives, living only for about two thousand years (8.18 "Threads").


For a very brief moment, the life of the Goa'uld Seth was told in the episode, 3.02 "Seth":
==Notable Characters==
 
[[Image:seth.jpg|thumb|170px|none|[[Seth]]]]
 
He had been left behind on Earth when the stargate was buried in Egypt. From that time, he took on new hosts every few hundred years and started religious cults. Every time he moved, he'd slaughter all of his followers and establish his new cult somewhere else. Daniel Jackson was able to track down Seth in Washington state in the United States. They infiltrated his compound, saved his followers from certain death, and killed Seth in the process. His compound, loaded with Goa'uld technology, was destroyed after Seth had tried to kill everyone with a bomb.
 
Nirrti was one of three System Lords who came to the SGC to negotiate with the Asgard for conditions in the Protected Planets Treaty (3.02 "Fair Game"). We met two other System Lords at this meeting:
{|

|valign="top"|[[Image:cronus.jpg|thumb|170px|left|[[Cronus]]]]
|valign="top"|[[Image:yuhuang.jpg|thumb|170px|left|[[Yu Huang Shang Ti]]]]
|}
Lord Yu was the most amicable of the three. Nirrti attacked Cronus and tried to frame Teal'c for the incident. Because she used cloaking technology in the attack and had not disclosed this technology to the other System Lords, she was taken as a prisoner by Cronus. Earth was successfully placed in the Protected Planets Treaty and was able to keep their Stargate Program intact.
 
In the episode, 2.18 "Holiday", SG-1 encountered a very old man named Ma'chello. SG-1 discovered that Ma'chello was on top of the Goa'ulds' Most Wanted list because he invented several ingenius weapons to combat them. The Goa'uld had captured him, hoping to make him a host in order to preserve his knowledge, but he escaped. His Goa'uld-killing technology, spread about like World War II mine fields, was able to wipe out the Linvris, a group of nine minor Goa'uld who opposed the System Lords. The identity of these nine Goa'uld was never revealed (3.04 "Legacy").
 
In the episode, 3.10 "Forever In A Day", Amaunet was encountered for the final time as she steals the Harsesis and sends her trusted aide away with him, keeping him from the clutches of Heru'ur. When Daniel found Amaunet in the tent near the battlefield where other Abydonians had been captive, Amaunet tried to kill him using the ribbon device. While the link between the two was made through the device, Sha're was able to send a message to Daniel asking him to forgive Teal'c for killing her and for him to find the boy and keep him safe. Teal'c killed Sha're when he stopped Amaunet's attack on Daniel. Later, in the episode, 3.20 "Maternal Instinct", Apophis slaughtered hundreds of Jaffa in his search for the Harsesis on Chulak. SG-1 was one step ahead in locating the child on the planet Kheb and it was there that they met the extremely powerful Ascended Being Oma Desala. Daniel was able to keep his promise to Sha're that the boy would be safe by letting Oma take the child as her own.
 
The story ends sadly for Sha're, but her brother Skaara was more fortunate. Heru'ur sent a battle group after Klorel, but the two motherships were destroyed when they entered Tollana's defense perimeter. Klorel's ship crashed on Tollana and through the injuries, Skaara was able to take control of his body long enough to ask the Tollan for help. The Tollan called SG-1 on behalf of Skaara to represent him in a trial known as a Triad in which it would be determined who would be given control of Skaara's body. For Klorel, the minor Goa'uld System Lord Zipacna answered the call (3.15 "Pretense"):
 
[[Image:zipacna.jpg|thumb|170px|none|[[Zipacna]]]]
 
A third, unbiased party was called into the Triad: Lya of the Nox. After much drama and the hearing of the arguments from both sides, Lya's vote was the deciding one. She chose to allow Skaara to have control of his body. The Tollan called the Tok'ra in to remove the symbiote from Skaara's body. They sent the symbiote to a planet under the control of the Goa'uld where a new host could be found for him. Skaara was free to return home to Aybdos.
 
In the episode, 3.19 "New Ground", SG-1 learned of the activities of a Goa'uld named Nefertum, son of Sekhmet. This Goa'uld transported people through the stargate years ago and a religion was born from it. Nefertum claimed to be the people's creator and placed them on the planet and this claim had the two major continents at war with each other: one side believing the creation story and the other side believing that they were brought through the stargate. Teal'c mentioned that he had done battle with Nefertum when he was in Apophis' service. Nefertum was an under-System Lord to Ra, but his current status or whereabouts were not revealed.
 
The SGC learned of a new alien race who were enemies of the Goa'uld in the episode, 3.21 "Crystal Skull". These aliens were associated with Toltec and Aztec mythology and it was Nicholas Ballard, Daniel's grandfather, who had discovered them back in the 1970's when he came across a crystal skull in a temple in Belize which transported him to the aliens' planet. SG-1 happened upon this same planet and eventually, was able to reunite Nick with his "Giant Aliens". The aliens invited Nick to stay with them so that they could exchange culture and knowledge, after Daniel was able to answer the riddle, "The enemy of my enemy is my friend," by stating that the Goa'uld were their enemies as well. The history of why the Goa'uld and the Giant Aliens were enemies was not revealed.
 
===Seasons Four and Five===
 
RECAP: Those Goa'uld still alive:
* Apophis - Found to still be alive when he attacked Chulak in search of the Harsesis.
* Cronus - One of the more powerful System Lords.
* Heru'ur - Lost several motherships in his attempt to kill Klorel, son of his enemy, Apophis.
* Klorel - The last time he was encounted, he was left without a host on a Goa'uld-controlled planet.
* Nirrti - Under arrest with Cronus for daring to attempt assassination.
* Yu Huang Shang Ti - One of the more powerful System Lords.
* Zipacna - Was in league with Klorel.
 
When Teal'c is contacted by a priestess of Chulak named Shaun'auc, he was, at first, quite pleased to see his old love once more (4.04 "Crossroads"). But, she came to convince him that she had been able to turn her symbiote against his genetic tendencies of evil-doing and she wanted to gain access to the Tok'ra to add her symbiote to their dwindling numbers. The Goa'uld symbiote deceived her and once he was given a host, he killed her. The name of the host given to him by the Tok'ra was Hebron of Parabal. The name of the Goa'uld was Tanith:
 
[[Image:tanith.jpg|thumb|170px|none|[[Tanith]]]]
 
Teal'c was not allowed to exact revenge for the death of Shaun'auc. The Tok'ra said that they would allow Tanith to live as long as he was useful and then they would destroy him.
 
Through Tanith, the Tok'ra were able to learn that Apophis and Heru'ur were considering an alliance to defeat the rest of the System Lords. At this point, Apophis and Heru'ur were said to have the largest of the Goa'uld armies. They were going to meet on neutral ground in the Tobin System. The Tobin Civilization originated from Earth thousands of years ago and had been extinct for centuries, but one of their legacies was a large mine field in space. The Tok'ra enlisted the help of Daniel Jackson to decipher the Tobin's Phoenician writings found in a manual for the mines, and with that knowledge they would set off one of the mines to make Apophis think that Heru'ur was attacking him. With this strategy, the Tok'ra believed that the power would become more evenly balanced among the remaining System Lords, rather than giving power to one Goa'uld. The plan backfired when Apophis escaped after Heru'ur was killed, and Apophis was able to absorb Heru'ur's remaining forces into his own (4.13 "Serpent's Venom").
 
Two more Goa'uld who took identities from Egyptian mythology were introduced in the episode, 4.14 "The Curse": Osiris and Isis. Osiris was the brother of Seth and Isis was Osiris' queen. They were discovered in canoptic jars, having been banished there by the other Goa'uld, in a shipment of Egyptian artifacts which had been sunken off of the coast of New Jersey, USA, but recently retrieved. During the study of these artifacts, the Osiris symbiote was released from his jar by Dr. Sarah Gardner and he took her as his new host. Dr. Gardner was an old lover and associate of Daniel Jackson's. It was discovered that the Isis symbiote died when the seal on her jar was broken in the shipwreck, but this information was not available to Osiris. Osiris killed Dr. Jordan, the lead archaeologist studying the artifacts, the curator of the artifacts, and the lab technician responsible for dating the artifacts, in the attempt to hide his tracks, but Daniel was close behind in identifying who was taken as his host. Before Daniel could do anything to prevent it, Osiris was able to take his hidden spaceship off of Earth, promising to make the rivers "run red with blood":
{|

|valign="top"|[[Image:isis.jpg|thumb|170px|left|[[Isis]]]]
|}
SG-1's android counterparts created in the First Season episode, 1.19 "Tin Man", were going out on missions. As it turned out, they arrived on a planet named Juna which had been previously visited by SG-1. SG-1 had helped the people overthrow Heru'ur's Jaffa after Heru'ur was killed. They reassured them that there would be no more invasions if they buried their stargate, but Cronus invaded with his ships and evidently unburied the stargate. The androids of Daniel, Carter, and Teal'c were captured by Cronus, but Jack's android was able to evade capture. With the help of one of the local men, Jack's android was able to convince SG-1 to come and help the people once more. In the process, all of the androids were destroyed, but not before Teal'c's android was able to kill Cronus as revenge for Cronus' killing Teal'c's father (4.21 "Double Jeopardy").
 
The Tok'ra once again called the Tau'ri for help. They heard that SG-1 had captured Cronus' mothership on Juna and they wanted it to help them move their base, including a stargate. While the move was happening, Tanith escaped and was able to summon Apophis. This opportunity was too good to pass up, so the Tok'ra decided that they'd explode the sun to take out Apophis' fleet. The Tok'ra were successful at evacuating the base, but Tanith escaped. Jacob Carter/Selmak, with the help of Major Carter, sent the stargate out to destroy the sun using a wormhole established to the gravitational pull of a black hole. Apophis' fleet was destroyed, but he was able to escape the nova, as were SG-1. They were thrown four million lightyears from their home galaxy, where they were met by a ship of Replicators which invaded Apophis' and SG-1's vessels. Apophis' ship was destroyed, but he was able to get onboard SG-1's. The Replicators were able to send the ship back to Apophis' base and Apophis was destroyed when the ship crashed on the planet. SG-1 and Jacob escaped in one of the cargo ships (4.22 "Exodus Part 1" and 5.01 "Enemies Part 2"). This time, SG-1 was 99% sure that Apophis was indeed really dead (5.02 "Threshold").
 
Nirrti returned to the picture when it was discovered that Cassandra, the lone survivor of Hanka who was now the adoptive daughter of Dr. Janet Fraiser, was going through some genetic changes once she reached her 16th birthday. SG-1 tracked Nirrti down to make her correct the genetic manipulation, but in return for saving Cassandra's life, Nirrti was released (5.06 "Rite Of Passage").
 
A new Goa'uld was introduced in the episode, 5.08 "The Tomb": Marduk. He had been entombed in a sarcaphagus in a ziggurat discovered by a Russian team. The Russians asked SG-1's help because their team had not reported back and no one could get inside of the ziggurat. Daniel was able to decipher the code to get inside and it was soon discovered that the Goa'uld symbiote was on the loose, taking whatever kind of host it could, including the creature buried with him in the sarcophagus meant to eat him alive and he would always remain alive with the healing capability of the sarcophagus. The original Russian team had let out the creature, with the symbiote inside of it, when they opened the sarcophagus. The symbiote took one of the Russian team members, Major Vallarin, as its new host:
 
[[Image:marduk.jpg|thumb|170px|none|[[Marduk]]]]
 
Marduk was killed when SG-1 destroyed the ziggarut with all of their C-4 right after they left the ziggarut through transporter rings that Daniel discovered there.
 
Tanith returned to plague the team once more in the episode, 5.09 "Between Two Fires". He had aligned himself with a new System Lord, but he didn't reveal who that System Lord was. He attempted to gain new weapons from the Tollan and in the process, he destroyed them.
 
It was discovered that the Russians had retrieved a Jaffa with a very mature symbiote which was in need of a host on their second mission through their stargate. This symbiote was bought by a billionaire named Adrian Conrad, who was dying of a rare condition which affects the immune system and makes the body vulnerable. He was hoping to find a way to implant himself with the symbiote, allow it to cure him, and then remove it. That didn't work and the Goa'uld took him over. We never learn the name of the Goa'uld (5.11 "Desperate Measures"):
 
[[Image:adrianconrad-goauld.jpg|thumb|170px|none|[[Adrian Conrad|Adrian Conrad as a Goa'uld Host]]]]
 
This Goa'uld was captured by Colonel Frank Simmons of the NID. Simmons kept him in a safehouse in South Dakota, putting the Goa'uld in a heavily guarded cage. Theirs was a relationship based on who could outsmart whom and what promises could be uttered and then broken. The Goa'uld was helpful, however, by providing the information necessary to successfully retrieve Teal'c out of the stargate buffer when the wormhole prematurely disengaged after Teal'c killed Tanith in a ship which crashed into the stargate in the episode, 5.14 "48 Hours".
 
The next encounter with the Goa'uld revealed the power structure of the System Lords. After Apophis and Cronus were destroyed, there was a great deal of in-fighting among the remaining System Lords for their domains. When they realized that they were destroying themselves, they called a truce and decided to meet in a neutral setting to hold a summit to define a new order. The summit was attended by the seven most powerful System Lords. One of the System Lords was unnamed and another was Lord Yu. The other five System Lords were:
{|
|valign="top"|[[Image:baal.jpg|thumb|170px|left|[[Ba'al]]]]
|valign="top"|[[Image:bastet.jpg|thumb|170px|left|[[Bastet]]]]

|-
|valign="top"|[[Image:morrigan.jpg|thumb|170px|left|[[Morrigan]]]]
|valign="top"|[[Image:olokun.jpg|thumb|170px|left|[[Olokun]]]]
|}
They discussed many issues, but one of the hottest topics of discussion was an unnamed adversary who was attacking them without revealing his identity. It wasn't until later that they discovered that Osiris was in league with this very ancient and thought to be dead Goa'uld: Anubis. Anubis was banished by the System Lords over a thousand years ago, and according to Osiris, the only System Lord remaining from that time was Yu. Anubis sent Osiris to the summit to request that he be voted back into the fold. In exchange, he promised to rid them of the Tok'ra and the Tau'ri. While the summit was taking place, Anubis had already sent Zipacna to destroy the Tok'ra base on Ravanna. That attack nearly wiped out the Tok'ra. Osiris said that before Anubis took his position with the System Lords, he would take care of the Tau'ri as well. All the System Lords at the summit, except for Yu, voted Anubis back in (5.15 "Summit Part 1" and 5.16 "Last Stand Part 2").
 
Anubis' method of getting rid of the Tau'ri and keeping the Asgard from intervening on their behalf was to attack the planet with an asteroid. This appeared to be a "natural" catastrophe, something the Asgard could do nothing about, according to the Protected Planets Treaty. SG-1 discovered that the asteroid contained naquadah after the Asgard said that they would not help, and by that time, they had to act on their own. They were able to send the asteroid through a hyperspace window through the Earth and ended up on the other side (5.17 "Failsafe").
 
A new Goa'uld was introduced in the episode, 5.18 "The Warrior". He disguised himself as a Rebel Jaffa named Kytano and acted as a charismatic leader under whom the Rebel Jaffa could organize. System Lord Yu revealed the imposter's identity to Teal'c and Teal'c challenged Kytano for his position of leadership. Kytano revealed his true identity as being the Goa'uld Imhotep. Teal'c killed him in the challenge.
 
[[Image:imhotep.jpg|thumb|170px|none|[[Imhotep]]]]
 
Another minor Goa'uld was introduced in the episode, 5.20 "The Sentinel". We never see his face, but his name is given as Svarog. He was attempting to conquer the planet named Latona, but eventually, the planet's defense system kicked in and all the aggressors vanished, presumably killed.
 
In the episode, 5.21 "Meridian", we learn that the Goa'uld Thanos (his name was revealed in the Season Seven episode, 7.14 "Fallout") experimented with a very powerful mineral called naquadria on the planet Kelowna 10,000 years ago. Evidence indicated that he nearly blew the planet to bits with his research. The Kelownans discovered their stargate and this research about 15 years prior to when SG-1 made contact with them. The Kelownans were attempting to create a bomb in preparation of a world war. During one of the experiments with the extremely dangerous and radiactive power core, an accident occurred while Daniel was touring the facility with the government's ethical advisor, Jonas Quinn. In order to prevent the entire planet from being destroyed from the impending blast, Daniel exposed himself to the radiactive core and dismantled it before it went critical. Daniel's body died from the radiation poisoning, but he escaped permanent death by becoming an Ascended Being with the help of Oma Desala.
 
Finally, at the close of Season Five, the Goa'uld Anubis is revealed in the episode, 5.22 "Revelations":
 
[[Image:anubis.jpg|thumb|170px|none|[[Anubis]]]]
 
Osiris and Anubis captured Thor of the Asgard and probed his mind for every bit of Asgard knowledge they could. This probing left Thor in a coma, but the three remaining members of SG-1 were able to save him.
 
===Seasons Six and Seven===
 
RECAP: Goa'uld who are alive at the beginning of this period are:
* Adrian Conrad's Goa'uld - Colonel Frank Simmons of the NID hid him away in a safe house in South Dakota, USA.
* Anubis - A strange-looking hooded figure who was recently voted back into the System Lord fold by six of the seven most powerful System Lords. Only System Lord Yu objected to his return.
* Ba'al - He was a major player at the summit and spoke as if he were the strongest of the seven there.
* Bastet
* Kali
* Klorel
* Morrigan
* Olokun
* Osiris - In service to Anubis.
* Zipacna - Also, in service to Anubis.
 
At the start of this period, Anubis had again attempted to rid the galaxy of the Tau'ri—this time by attacking the stargate. He was using a weapon which bombarded the stargate with enough energy to make it go critical. The resulting explosion would wipe out the entire world. The SGC was able to strap the stargate to the X-302, take it far into space through a hyperspace window, and allow it to explode far from Earth. Once again, Anubis' plan to destroy the Tau'ri failed (6.01 "Redemption Part 1" and 6.02 "Redemption Part 2").
 
The next group of Goa'uld encountered by SG-1 were clones of the one which Adrian Conrad had implanted into himself. They were immature and were only able to take over their hosts during the nighttime while their hosts slept. During the night, they were busy building a Goa'uld spacecraft in a warehouse in the "sleepy" town of Steveston, Oregon. The NID was aware of this and let it continue because they wanted access to the technology. The Goa'uld, however, were planning on infiltrating the NID and the SGC once they discovered that they were being watched. They didn't know that the genetic engineer who created them built into them a kill switch in which they would die when exposed to a certain antibiotic. The townspeople were given the antibiotic not knowing what had truly happened to them and the unfinished spaceship was taken to Area 51 for study (6.05 "Nightwalkers").
 
A woman was discovered buried in the ice of the Antarctic, not far from where the second stargate was found (1.18 "Solitudes"). As it turns out, she was carrying the plague which wiped out the Ancients and she exposed SG-1 to it. She had healing powers, but each time she used them, she grew weaker until she finally succumbed. The only person left to be cured was Jack. He was given the opportunity to receive a Tok'ra symbiote named Kanan to cure himself and to provide a temporary host so that Kanan could reveal important information he had gathered on his last mission before his own host was killed. Jack was cured by the Tok'ra, but the Tok'ra took advantage of Jack by hijacking his body to go and rescue his lover from Ba'al's hidden fortress. They were captured and Kanan left Jack's body. Ba'al repeatedly tortured Jack for information about the Tok'ra, killed him, and then revived him in the sarcophagus. As an Ascended Being, Daniel came to Jack's rescue by nudging Teal'c with an idea while Teal'c was deep in kel-no-reem. Teal'c was able to get System Lord Yu to attack Ba'al's fortress because Ba'al had been working on anti-gravity technology in secret. Jack was able to escape with Kanan's lover, Shallan, who decided to stay with the Tok'ra in honor of Kanan (6.04 "Frozen" and 6.06 "Abyss").
 
SG-1 helped the Tok'ra in an undercover operation in which they would purposefully get themselves captured and brought into the presence of the Goa'uld Khonsu, who actually happened to be a Tok'ra spy. Khonsu had a Jaffa named Her'ak in his service who killed him and took SG-1 hostage for himself, revealing that he was in service to Anubis. This Jaffa later became Anubis' First Prime. SG-1 was able to escape from Her'ak before they were presented to Anubis (6.08 "The Other Guys").
 
Anubis learned of the Tok'ra's hidden base in the Risa System and attacked it. The Tok'ra did not know that there was an Ashrak in their midst when they escaped to the Alpha Site, already the home to Rebel Jaffa and some SGC personnel. The Ashrak attempted to set the Jaffa and Tok'ra off on each other, but they united instead when the Ashrak's presence was revealed (6.09 "Allegiance").
 
[[Image:ashrak2.jpg|thumb|170px|none|[[Ashrak|Ashrak in the service of Anubis]]]]
 
Adrian Conrad's Goa'uld attempted to steal the latest advancement in Tau'ri technology, the X-303 battle cruiser, later named ''Prometheus''. Colonel Frank Simmons was also in league with him and they were successful at getting the spaceship out of its subterranean bay and into hyperspace, ending at a location out in the middle of nowhere. Adrian Conrad was killed in a fight and the symbiote jumped into Colonel Simmons, who was subsequently killed by Jack when Simmons attempted to kill him and Teal'c. Fortunately, Thor of the Asgard detected their presence and was able to lead them home (6.11 "Prometheus" and 6.12 "Unnatural Selection").
 
Nirrti was discovered on a planet by the Russian SG team and SG-1 and the Russian team returned to the planet to help the people gain their freedom. She was continuing her genetic research in order to produce the perfect host and was using the people of the planet as her guinea pigs, telling them that she was attempting to cure them from a disfiguring disease. The disfiguring was actually the result of her manipulations. The people learned the truth about her and were able to free themselves of her by killing her, using the powers that she had given them through the manipulations. They discovered how to reverse the DNA alterations with her machine before killing her and they promised SG-1 that they would destroy the machine once all of their people were restored (6.16 "Metamorphosis").
 
SG-1 was invited to be on the ''Prometheus'' when it got taken out for a test of the hyperdrive engines powered by naquadria, a mineral known to be unstable. The engines failed and they had to eject the core before it destroyed them. They ended up at a planet Tagrea, which Jonas knew had a stargate, but the Tagreans were not aware of it. SG-1 learned that the planet had belonged to the Goa'uld Heru'ur but had been abandoned by him when their resources ran out. In defiance, the people buried the stargate and eliminated all records of Heru'ur's existence. SG-1 found the stargate and established a relationship with the Tagreans (6.20 "Memento").
 
The Goa'uld Mot was in the service of Ba'al and he regularly visited the planet P4S-237 to receive a tribute of naquadah. Unknown to the people of the planet, Lord Mot was hoarding the naquadah in a plan to overthrow Ba'al himself. It had been known that Ba'al had stopped receiving the naquadah and had assumed that the mines were no longer productive. Lord Mot revealed to SG-1 of his plans to overthrow Ba'al, who was currently under Anubis in strength. Mot was killed by one of the people of the planet (6.21 "Prophecy"):
 
[[Image:mot.jpg|thumb|170px|none|[[Mot]]]]
 
Anubis was the next Goa'uld heard from at the end of Season Six in the episode, 6.22 "Full Circle". An amazing number of significant events occurred in this episode, but the ones of importance concerning the Goa'uld include:
* Daniel, as an Ascended Being, recruited SG-1 to help save Abydos when he learned that Anubis was searching there for the Eye of Ra, a component which when joined with other Eyes would create a superweapon.
* Daniel discovered a tablet which told of what became of the Ancients: some of them learned to ascend and became known as "The Others" and the rest died from the plague. He also learned from the tablet that the Ancients left behind a city which was said to have a vast store of weapons which could be used to gain power in the galaxy if Anubis discovered its location. This city has been since referred to as the Lost City of the Ancients. Daniel realized the importance of finding the Lost City before Anubis did and told Jack to give the Eye of Ra to Anubis so that they would be granted safe passage and could get off of the planet alive with the tablet.
* Daniel learned that Anubis was once a Goa'uld with a human host, but had somehow learned how to ascend. The Others tried to kick him out of their plane of existence, but were not successful, so Anubis was left as some form of energy, stuck between the corporeal and the ascended forms.
* Daniel informed the rest of the System Lords where Anubis was and about the superweapon and the System Lords, including Yu and Ba'al, attacked him in orbit over Abydos.
* Significant damage was done, but Anubis was the victor and he turned his attention to using his new superweapon on Abydos as a test.
* Daniel attempted to buy more time for SG-1 to get off of the planet through the stargate by confronting Anubis.
* SG-1 got off of the planet with the tablet, but Daniel was forcibly removed from Anubis' presence before he was able to wipe Anubis from existence. It was not revealed who removed Daniel since it could have been either Oma Desala or The Others.
* Anubis used the superweapon and destroyed Abydos, killing everyone with the blast, but Oma Desala helped all of the Abydonians ascend.
 
At the start of Season Seven, Daniel Jackson is returned to human form and left on the planet Vis Uban to be discovered by his friends (7.01 "Fallen Part 1"). His memories were buried either by choice or as a punishment for his actions against Anubis on Abydos. SG-1 convinced him to return home with them and as soon as he was there, he started to remember who he was. It was not long after this that he got involved with SGC's plan to destroy Anubis' superweapon that he used on Abydos and on the other System Lords, making Anubis more and more powerful. The plan worked and soon Anubis was without his superweapon, and with the help of the System Lords under the leadership of Ba'al, he was without his magnificent ship as well. Anubis, however, was able to escape (7.02 "Homecoming Part 2").
 
Ba'al gained more power after this leveling of Anubis (7.04 "Orpheus" and 7.09 "Avenger 2.0"), but Anubis was not one to be put down for long. Soon, he was building a vast army of Kull Warriors who were the product of genetic engineering. These warriors were implanted with a Goa'uld symbiote which was programmed to be completely loyal to Anubis. This loyalty was something that Anubis knew he could not depend upon from his Jaffa. Anubis was using his knowledge gained from being one of the ascended to create these Kull Warriors by animating their laboratory-grown inanimate tissue with a device similar to the sarcophagus. This technology was once that of the Ancients and it came to be known as Telchak's Device. Telchak was the Goa'uld who discovered the technology a long time ago and developed the first sarcophagus from it. Daniel and fellow civilian scientist Dr. Bill Lee were able to find the Telchak Device in Honduras using the research notes left behind by Daniel's grandfather, Nicholas Ballard (7.11 "Evolution Part 1" and 7.12 "Evolution Part 2"). Along with the Tok'ra, Major Carter was able to develop a weapon to counteract the Kull Warrior's life-giving energy (7.16 "Death Knell").
 
[[Image:kullwarriorfull.jpg|thumb|170px|none|[[Kull Warrior]]]]
 
In the episode, 7.10 "Birthright", we are introduced to another Goa'uld. His name is Moloc, but we don't see his face. He started a ritual among his Jaffa that all female babies were to be burned as soon as they were born. He could do this for a few hundred years before it would negatively affect his Jaffa population. Many of his priestesses started a new colony in secret where they would rescue the babies and raise them there. A major problem from this showing of mercy was that eventually the girls would need symbiotes to live (Moloc's Jaffa were genetically engineered to need a symbiote at puberty). The leader of the group, Ishta, would take her female warriors out on raids and kill Moloc's male Jaffa for their symbiotes. SG-1 was able to introduce them to tretonin so that they would no longer kill their brethren, many of whom were wanting freedom from the Goa'uld as much as they.
 
Because Ba'al had led the System Lords to destroy Anubis while he was testing out naquadria while hovering over the capital city of Kelowna (the nation on the planet with the same name), Ba'al took an interest in the mineral himself. He sent a Goa'uld to the planet and had it take one of the local scientists, Kianna Cyr, as a host, gaining secrets through her position. Naquadria was created as a result of Thanos' experiments and the Kelownans mined the mineral to power their bomb (this is the same bomb research that killed Daniel in Season Five). They tested the bomb and started a chain reaction that would lead to the planet's destruction when the conversion of the vein of naquadria reached the planet's core. The unnamed Goa'uld decided it wanted the naquadria for itself so that it could harness its power instead of Ba'al, but its plans backfired and it ended up dead in the process. Before it died, however, it saved both the planet and Kianna Cyr (7.14 "Fallout").

Osiris, still working under Anubis, knew that the Tau'ri were searching for the Lost City of the Ancients and that Daniel had once been ascended. The assumption was that he knew of the location of the Lost City, but it was buried in his subconscious. Using modified memory devices, Osiris visited Daniel as he slept and invaded his dreams with false images of his time with Sarah Gardner and his attempt to decipher a tablet. This tablet was supposed to help Daniel recall his memory of where the Lost City was located, if he ever knew. Daniel realized what was happening and with the rest of his team set a trap to capture Osiris the next time he visited. Daniel wanted to remember where the Lost City was, but soon the morning was upon him and he still had not remembered. They were successful at capturing Osiris and the Tok'ra removed him from Sarah. It was not revealed what the Tok'ra did to the symbiote, but it can be fairly assumed that Osiris is dead (7.15 "Chimera").


In the episode, 7.19 "Resurrection", a rogue NID cell created a human-Goa'uld hybrid named Anna. She was given the genetic memory of the Goa'uld named Sekhmet who had been in service to Ra (Sekhmet is also said to be the mother of Nefertum, the Goa'uld of 3.19 "New Ground"). It was determined that the Germans had uncovered a canopic jar with the Sekhmet symbiote and that jar reached the possession of Dr. Keffler, son of a convicted Nazi war criminal. Dr. Keffler used Anna as a medium to access the Goa'uld genetic memory and his treatment of her was repulsively inhumane. He didn't see her as a person, but merely as a way to get to the information. The entire staff of the lab died in this episode, including Dr. Keffler and Anna, but nothing was said of what became of the Goa'uld symbiote. Most likely it is dead, since it doesn't have to be alive in order for one to cultivate its DNA.

Continuing on the search of the Lost City, the SGC remained only one step ahead of Anubis. When the SGC was discovered to have a presence on the planet P3X-666, Anubis sent ships to attack them. In the battle, Dr. Janet Fraiser was killed (7.17 "Heroes Part 1" and 7.18 "Heroes Part 2"). The SGC gained another step ahead upon discovering an Ancient's Repository of Knowledge on the planet P3X-439, but once Anubis was attacking, Jack decided to take the download once again (he had done in previous in the Season Two episode, 2.16 "The Fifth Race"). Eventually, the knowledge he gained helped them locate an Ancient outpost in Antarctica and Jack was able to activate a weapon which destroyed all of Anubis' attacking fleet he had sent to Earth (including Anubis himself). Although the weapon was powerful, Daniel concluded that the outpost in Antarctica was not the actual Lost City of the Ancients because the outpost was not big enough to match the description of the city. Jack placed himself in a stasis pod at the outpost when he realized that he was about to die because the knowledge of the Ancients was overloading his system (7.21 "Lost City Part 1" and 7.22 "Lost City Part 2").

===Season Eight===
===Other===


RECAP: Goa'uld assumed to be alive and active at the beginning of this period:
* [[Jack O'Neill|Col./Brig. Gen. Jack O'Neill]]
* Ba'al - He was an active Goa'uld during Season Seven, even though we never saw him.
* [[Daniel Jackson|Dr. Daniel Jackson]]
* Bastet - She was mentioned in the Season Seven episode, 7.02 "Homecoming Part 2".
* Kali
* Klorel
* Moloc - Introduced in the Season Seven episode, 7.10 "Birthright".
* Morrigan
* Olokun - He was mentioned in the Season Seven episode, 7.16 "Death Knell".
* Zipacna
 
Season Eight started right off the block with more information about the state of Goa'uld affairs and introduced two new System Lords:

|valign="top"|[[Image:amaterasu.jpg|thumb|170px|left|[[Amaterasu]]]]
|}
After Earth's successful destruction of Anubis' attacking fleet, the System Lords took advantage of Anubis' defeat and agreed to divide the spoils evenly among themselves. Ba'al, however, decided to take more than his share, including reprogramming Anubis' Kull Warriors to be loyal to him, and the other System Lords were wanting Earth to help them even the playing field by eliminating Ba'al with the same weapon we used to defeat Anubis. They sent three System Lords to represent their interests: Camulus, Amaterasu, and Yu (along with his First Prime Oshu). Negotiations between the SGC and the System Lords did not go well and so the System Lords decided to send a ship to test out Earth's defenses. Ba'al destroyed that ship before it reached Earth and the System Lords were asked to leave. Camulus, however, asked for asylum because his army was no more and he had nothing with which to fight. He felt that he could offer more help staying on Earth. The other System Lords looked upon him as a traitor to his kind (8.01 "New Order Part 1" and 8.02 "New Order Part 2").

==Alliances==
 
* The Goa'uld serve only their own interests, but some of them have joined together in an organization of System Lords to exert supremacy in the galaxy.
 
==Enemies==
 
* [[Asgard]] - The Asgard have a Protected Planets Treaty signed with the System Lords which attempts to keep the Goa'uld in check. The terms of this treaty are not revealed in detail and it seems to be absolutely worthless.
* [[Giant Aliens]] - We don't know why these aliens have declared the Goa'uld their enemy, but they have.
* [[Ma'chello]] - He was a thorn in their side for many years and could not be caught. He died in the SGC infirmary, but he left behind many of his Goa'uld-killing inventions as if placing carefully-concealed mine fields.
* [[Rebel Jaffa]] - The movement of the Jaffa was started by Teal'c and their numbers are growing stronger. Anubis attempted to replace his untrustworthy Jaffa with the genetically-engineered Kull Warriors.
* [[Reetou]] - The Reetou wish to eliminate the Goa'uld race entirely. Some rebel factions of their race have gone so far as to attempt to eliminate all potential hosts, including those humans on Earth.
* [[Replicators]] - The Replicators are everyone's enemy because they don't play political games at all—they just consume everything they can to reproduce and this includes the advanced technology that the Goa'uld possess.
* [[Tau'ri]] - It seems the war with the Goa'uld began as soon as the Goa'uld Ra set foot on Earth seeking a new kind of host for his dying race. Even though the ancient Egyptians were successful at banishing him, many of the removed humans of Earth have become slaves of the Goa'uld, including the Jaffa who were genetically altered to carry the Goa'uld symbiotes in pouches.
* [[Tok'ra]] - Their movement was started by the Goa'uld Egeria who first opposed Ra (Tok'ra means ''against Ra''). They work through subterfuge and have been doing so for thousands of years. Because their numbers have dwindled significantly, they have had to regroup and return to their old ways without keeping an alliance with the Tau'ri.

A Goa'uld Symbiote
A Goa'uld Host's eyes glow

Summary

The Goa'uld are aquatic parasitic creatures that evolved into intelligent, but extremely evil, beings. A symbiote, as it is also known as, invades a host, usually human, through the back of the neck (some have been known to go through the front) and blends into the host's biological structure, attaching itself into the brain and thus gaining access to the host's knowledge and voluntary muscular system. The term "Goa'uld" is applied to both the symbiote itself and the blended host, since the host of a Goa'uld is prevented from exerting his own personality after the blending.

The Goa'uld have existed for a very long time, but they have been most successful in exerting their power since they took humans as hosts (their first hosts, the Unas, evolved on the same planet, P3X-888). The First World, Earth, was found by the Goa'uld Ra 10,000 years ago. He was searching for a new type of host for his dying race. He found that the human body made a very good host and was easily maintained through the use of the sarcophagus, a device capable of rapid healing, even from death.

Since Ra's visit to Earth, the Goa'uld have favored human beings as hosts and have taken groups of people from Earth to other planets suitable for them. They found the network of Stargates left behind by the Ancients to be a most useful tool, since the planets on which these Stargates were found were very Earth-like and would make perfect human-sustaining environments. The Goa'uld would visit these planets and take the most beautiful and healthy people to become new hosts. Teal'c described the visits as "harvests", to which Daniel replied, "You know, I wish you wouldn't say 'harvest'. We're talking about human beings, not brussel sprouts." Teal'c's responded to this by saying, "That is how the Goa'uld perceive it."

The Goa'uld perceive humans as "brussel sprouts" because they have genetic memory that gives them great knowledge. With each generation, however, access to this extraordinary knowledge produced a "god complex" and they became increasingly evil. To ensure their supremacy, they scavanged the galaxy for the latest technological advances. If a world began to show technological progress, the Goa'uld destroyed it or took it over and forced the inhabitants into slavery. Usually, this slavery included mining the precious mineral naquadah on which much of the Goa'uld's technology depended. When the mines ran dry, the Goa'uld usually abandoned the planets, leaving the people to fend for themselves. In some cases, the people were successful in overthrowing their oppressors and buried the Stargate to prevent the Goa'uld's return. The burying of the Stargate, however, did not always guarantee that the world would be free from the Goa'uld threat indefinitely, since the Goa'uld possessed starships capable of traveling exceedingly fast through hyperspace windows.

In the process of building their power, the Goa'uld made allies and enemies. As far as allies go, however, any arrangements made between the Goa'uld were usually short-lived and only lasted as long as a specific purpose was served, this purpose most often being to maintain the balance of power.

Since opening the Stargate on Earth, Stargate Command (SGC) was plunged into the middle of the galactic power struggle. Their first trip through the Stargate sent them to Abydos, a planet peopled by the descendants of Ancient Egyptians. The Abydonians slaved in the naquadah mines and worshipped Ra as their god for thousands of years. Col. Jack O'Neill and Dr. Daniel Jackson helped free the people by destroying Ra and his starship in orbit. Ra was the most powerful and feared of all the Goa'uld System Lords. After his death, the balance of power was forever changed and, subsequently, those who had hoped to overthrow the Goa'uld were given a fighting chance.

The struggle for the balance of power among the System Lords lasted nine years (since the death of Ra), until only the System Lord Ba'al remained of any great significance. His role, however, was reduced greatly when the Rebel Jaffa convinced the remaining Jaffa armies that the Goa'uld were not gods and they took the temple on the planet Dakara that was deep in Ba'al's territory. Ba'al lost his army, his territory, and his ships in the final battle among the Goa'uld, Rebel Jaffa, Tau'ri, Tok'ra, and Replicators over the planet Dakara.

Although not all of the Goa'uld are dead, the great power that they enjoyed for thousands of years no longer remains.

This series of articles covers each Goa'uld personality that the SGC has encountered since Daniel Jackson reopened the Stargate (Stargate: The Movie):

Alliances

It is in the nature of the Goa'uld to serve only their own interests and basically operate on their own. However, within the race, there were some alliances formed when one group of Goa'uld wished to overthrow another.

System Lords

The Goa'uld formed a feudal system of galactic rule in which the most powerful were known as System Lords. These System Lords created a High Council that exerted itself whenever one of their own began to gain too much power. The High Council was also a means by which the System Lords could unite to defeat a common enemy. They took votes on requests for a seat on the Council, but this vote did not have to be unanimous (5.16 "Last Stand Part 2"). They also required a fully-assembled Council in order to vote to stop any action they had originally agreed upon (8.02 "New Order Part 2"). The number of members of the High Council varied as System Lords came and went, but the latest estimate the SGC had indicated that the Council had around a dozen members (8.01 "New Order Part 1"). The last of the High Council died at the hands of the Replicators (8.16 "Reckoning Part 1").

  • When the System Lords saw the humans of Earth, called the Tau'ri, as a threat after SG-1 eliminated several of their most powerful within a very short period of time, their attention was directed toward Earth as a possible planet for conquest or destruction. The Asgard found out about this and decided to add Earth to their list of protected planets in the Protected Planets Treaty they had with the Goa'uld System Lords. In this agreement, the Goa'uld promised that they would not destroy Earth because they feared the Asgard's supreme weaponry. Three System Lords came to Earth to represent the interest of the High Council and to negotiate with Thor of the Asgard. (3.03 "Fair Game")
  • The System Lords called a summit of the High Council after the defeats of Cronus and Apophis, both of which SG-1 had helped accomplish (4.21 "Double Jeopardy" and 5.01 "Enemies Part 2", respectively). The seven most powerful System Lords met in this summit to create a new order because they had created too many losses among their own power bases fighting amongst themselves in their attempt to gain the control of the vacated domains of the two former System Lords. They also needed to deal with a common enemy, Anubis, who had once been among them but had been banished for crimes that were unspeakable even for the Goa'uld. Anubis was quickly gaining power and the High Council decided to permit him to rejoin them as a fellow-System Lord rather than fight him as an enemy. Before he took his position on the High Council, Anubis promised to get rid of the Tok'ra and the Tau'ri since he wasn't bound by the Protected Planets Treaty. (5.15 "Summit Part 1" and 5.16 "Last Stand Part 2")
  • Anubis failed in annihilating the Tok'ra and the Tau'ri and most likely never gained his seat back on the Council, even though he had been voted back in. When he was collecting weapons enhancement technology, called Eyes, to create a powerful superweapon on his mothership, the System Lords, led by Yu who had opposed his readmission, attacked Anubis in orbit over Abydos. The System Lords were not able to defeat him and after losing several ships, they retreated. Anubis destroyed Abydos as a demonstration of his power and as a reminder to SG-1 not to challenge his position again, since it had been Daniel, as an Ascended Being, and SG-1 who had attempted to protect Abydos and prevent his rise in power. (6.22 "Full Circle")
  • The SGC involved the High Council of the System Lords once again in opposing Anubis by baiting him with the possible location of the Lost City of the Ancients that was supposed to have a powerful weapons cache that would guarantee the possessor of galactic supremacy. The System Lords, under the leadership of Yu, was supposed to assemble over the planet Vis Uban after the SGC eliminated his superweapon. But, because Lord Yu was showing senility, his First Prime Oshu asked that Ba'al lead the combined fleet against Anubis. Ba'al did this and Anubis' mothership was destroyed in the skies of Kelowna (Jonas Quinn's homeworld), but Anubis escaped. (7.01 "Fallen Part 1" and 7.02 "Homecoming Part 2")
  • After Anubis was defeated through the use of the powerful weapon left behind by the Ancients on Earth in their Antarctic Outpost, the System Lords sent three representatives to Earth to discuss regaining the balance of power by eliminating Ba'al who had been taking more than his fair share of Anubis' domain. As a test of Earth's strength and that of the Asgard, the System Lords sent a ship to provoke Earth into using the Ancient weapon, but Ba'al destroyed the ship before it made it to Earth. The System Lords did not get their demonstration of the weapon and were sent home to continue their struggle against Ba'al. (8.01 "New Order Part 1" and 8.02 "New Order Part 2")
  • Ba'al's rise in power meant that many of the System Lords either died or capitulated. Eventually, only three System Lords remained: Lord Yu and two others. They were massacred on their summit space station by Replicator Carter, so that only Ba'al remained in power. (8.16 "Reckoning Part 1")
  • Ba'al's total dominance, however, was kept in check by Anubis, who had himself regained much of his power after his defeat over Antarctica. These two System Lords joined forces in order to defeat the Replicators and the Rebel Jaffa, but they suffered a major blow with the destruction of their fleets in orbit over the planet Dakara, located deep within Ba'al's territory. Ba'al assisted the Tau'ri and Tok'ra in destroying the Replicators using the weapon left behind by the Ancients on Dakara, and Anubis discovered his betrayal and promised he'd live only to see the entire galaxy destroyed. Anubis was stopped in remaking the galaxy in his "grand design" by Oma Desala who engaged him in an eternal battle on the ascended plane. Ba'al remained, but his fleets, territory, and armies were no longer his. The System Lords are now no longer. (8.17 "Reckoning Part 2", 8.18 "Threads")

Linvris

The Linvris was a group of nine Goa'uld who opposed the System Lords. They never gained much power and were killed by inventions left behind by Ma'chello, a man who had been placed on top of the System Lords' most wanted list because he had become a major threat to their existence. (3.04 "Legacy")

Enemies

Asgard

The Asgard had a Protected Planets Treaty signed with the System Lords that attempted to keep the Goa'uld in check. The terms of this treaty were not revealed in great detail and it seemed to be absolutely worthless once the System Lords gained more advanced technology to overpower even the Asgard. After the defeat of the System Lords and Replicators, the Asgard withdrew for a time to address their cloning issues. After realizing that their generations upon generations of extending their lives through cloning had produced a rapidly degenerating disease, the Asgard decided to end their lives in an act of mass suicide. They gave Earth all of their knowledge and advanced technology before their homeworld Orilla exploded during an attack by the Ori. They destroyed their world to prevent their advancements from falling into enemy hands (10.20 "Unending").

  • The Asgard added Earth to the Protected Planets Treaty (3.02 "Fair Game"). This agreement did not bind the Goa'uld who were not part of the High Council and stated that the Asgard could not use their technology to save a protected planet if it was threatened by natural causes. These two points were used against Earth when Anubis attempted to destroy Earth by sending a naquadah-rich asteroid on a collision course (5.17 "Failsafe") and sending a build-up of energy through the Stargate (6.01 "Redemption Part 1" and 6.02 "Redemption Part 2").
  • While attempting to protect a planet that had a valuable Asgard genetic research facility, Thor's ship was destroyed and he was taken prisoner by Osiris and Anubis. Neither one of these Goa'uld were bound by the Treaty, evidently. Anubis used a mind probe on Thor that gave him access to all of the Asgard's technological and strategic knowledge and, with this knowledge, Anubis became the most powerful Goa'uld System Lord. (5.22 "Revelations")
  • Anubis attempted to destroy Earth a third time by sending an attack fleet composed of over thirty vessels. SG-1 found a powerful weapon built by the Ancients in an outpost they had in Antarctica. After Anubis' destruction, the System Lords sent three of their representatives to Earth to ask for help in destroying Ba'al who was greedily taking more than his fair share of Anubis' domain. These representatives stated that Ba'al intended to go after the planets of the Protected Planets Treaty (27 planets, including Earth) because he believed that the Asgard no longer exercised power in the galaxy. (8.01 "New Order Part 1")

Giant Aliens

The Giant Aliens are associated with Toltec and Aztec mythology and it was Nicholas Ballard, Daniel's grandfather, who had discovered them back in the 1970's when he came across a crystal skull in a temple in Belize that transported him to the aliens' planet. SG-1 happened upon this same planet and eventually, reunited Nick with his "Giant Aliens". The aliens invited Nick to stay with them so that they could exchange culture and knowledge, after Daniel answered the riddle, "The enemy of my enemy is my friend," by stating that the Goa'uld were their enemies as well. The history of why the Goa'uld and the Giant Aliens were enemies was not revealed. (3.21 "Crystal Skull")

Ma'chello

Ma'chello's life was dedicated in eliminating the Goa'uld by inventing various weapons against them. The Goa'uld took his wife as a host and attempted to have him taken as well in order to preserve his knowledge. He escaped before being implanted. He died in the SGC infirmary, but he left behind many of his Goa'uld-killing inventions as if placing carefully-concealed mine fields. (2.18 "Holiday" and 3.04 "Legacy")

Rebel Jaffa

The movement of the Jaffa to end the tyranny of the Goa'uld was started by Teal'c, and their numbers began to grow once he made the call to fight against the false gods (3.01 "Into The Fire Part 2"). The Jaffa were genetically-altered humans of Earth who were engineered to carry the Goa'uld symbiotes to maturity in an abdominal pouch to improve the symbiote's chances of successfully blending with a host (1.03 "The Enemy Within"). Without the Jaffa, a symbiote had a one-in-two chance of success (6.10 "Cure"). The Jaffa's entire immune system depended on the symbiote's natural healing capabilities. The symbiotes gave the Jaffa long lives and good health, but the Jaffa depended on the symbiotes for their very survival. The Goa'uld used the strong Jaffa as soldiers and the others served them in their temples. Teal'c knew that the Goa'uld were not gods, as the Jaffa were taught since birth, but parasites. The Rebel Jaffa who answered his call built their numbers and hoped one day to free all of their brethren. At one time, they took sanctuary at the SGC's Alpha Site (6.09 "Allegiance"), but decided to strike out on their own after the Alpha Site had been discovered by Anubis and destroyed (7.16 "Death Knell"). It was most likely because of the Rebel Jaffa that Anubis replaced his Jaffa with the genetically-engineered Kull Warriors (7.11 "Evolution Part 1" and 7.12 "Evolution Part 2"). Ultimately, in the fateful encounter over the skies of the planet Dakara, the Jaffa won their freedom when the Goa'uld System Lords Ba'al and Anubis were defeated and the remaining army of Kull Warriors were destroyed (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads"). The struggle to form a strong, independent nation began at the same place where the Jaffa were created by the Goa'uld — on Dakara (8.18 "Threads"). After the Ori destroyed Dakara, the Free Jaffa Nation splintered as they struggled for their own survival (10.07 "Counterstrike").

Reetou

The Reetou are an insect-like alien species that are 180 degrees out of phase with the humans of Earth, so they are invisible to the naked eye. The Goa'uld attempted to destroy the Reetou and as a result, Reetou rebel forces believed that the only way to get rid of the Goa'uld was to eliminate all possible hosts. It was this extreme reasoning that led this group of Reetou to attempt to destroy Earth. (2.20 "Show and Tell")

Replicators

The Replicators were everyone's enemy because they didn't play political games at all—they just consumed everything they could to reproduce and this included the advanced technology that the Goa'uld possessed. The Replicators were primarily the enemy of the Asgard, but they were instrumental in the spectacular demise of Apophis before they evolved into human form (5.01 "Enemies Part 2"). Replicator Samantha Carter led the Replicators against the Goa'uld and nearly destroyed them, but she and all of her "brethren" were destroyed through the joint effort among the Goa'uld, Rebel Jaffa, Tau'ri, and Tok'ra (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2").

Tau'ri

The Tau'ri, humans of the First World (Earth), became an enemy of the Goa'uld as soon as Ra landed his spaceship in Eygpt seeking a new kind of host for his dying race in 8000 B.C. Like Ra, many of the Goa'uld who took the humans as hosts took on the identity of other gods of Earth, including those from Babylonian, Canaanite, Celtic, Chinese, Egyptian, Greek, Hindu, Japanese, and Roman mythologies (the word "Goa'uld" means "god"). Since the Tau'ri reopened the Stargate on Earth and organized Stargate Command (SGC), they gave the Goa'uld reason to seriously consider that their days were numbered as the most powerful force in the galaxy. The Goa'uld System Lords were finally defeated after eight years of war, and they no longer posed the threat that they once did for thousands of years (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads", 8.19 "Moebius Part 1").

Tok'ra

The Tok'ra were started over 2000 years ago by the Goa'uld Egeria who first opposed Ra (Tok'ra means against Ra) and his enslaving of the humans he took through the Stargate (4.04 "Crossroads"). All the Tok'ra are descendants of Egeria and, therefore, inherited her Goa'uld genetic memory and her desire to have a truly symbiotic relationship with the host. The Tok'ra do not use the sarcophagus, but instead, take new hosts when the host is about to die (most human hosts of the Tok'ra live to be close to 200 years old). They worked against the Goa'uld through subterfuge. Because they are of the same race as the Goa'uld, there was no way for the Goa'uld to tell the difference between one of their own and a Tok'ra, and the Tok'ra used this to their advantage by infiltrating the ranks of the System Lords and assuming the role of a minor Goa'uld in the System Lord's service. (2.11 "The Tok'ra Part 1" and 2.12 "The Tok'ra Part 2") The Tok'ra moved their underground bases of operations continuously, but, at one point, they took residence at the SGC's Alpha Site (6.09 "Allegiance"). Their stay on the Alpha Site was short because they were at a greater risk of being discovered with both the Tau'ri and Rebel Jaffa living there. Because of their dwindling numbers (Egeria was banished thousands of years ago and did not produce any more Tok'ra offspring), they decided to return to their underground bases (7.16 "Death Knell"). Egeria was discovered in stasis on one of Ra's former planets and died soon thereafter, basically guaranteeing the end of the Tok'ra once the last one dies (6.10 "Cure"). Despite this, the Tok'ra continued to oppose the Goa'uld and fought for the freedom of their slaves, human and Jaffa alike (6.19 "Changeling"). The Tok'ra lived to see the defeat of the Goa'uld System Lords (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2", 8.18 "Threads"), but their lives are close to an end because they do not use a sarcophagus to extend their lives, living only for about two thousand years (8.18 "Threads").
