Tau'ri-Goa'uld War

The Tauri-Goa'uld War (1994-2005) was a conflict fought between the Tau'ri of Earth and the Goa'uld, a conflict which saw the fall of the System Lords and the collapse of the Goa'uld Empire.

Beginnings (1994-1997)
The war started when humans from Earth travel to Abydos and run into the Supreme System Lord Ra. The team that travels to that planet lead a rebellion and Ra was ultimately killed by Colonel Jack O'Neill and Dr. Daniel Jackson who send a nuclear warhead to Ra's ship, where it explodes, killing him and leaving a power vacuum within the System Lords.

Two years later, Apophis came to Earth looking for a host for his queen Amonet. His First Prime Teal'c was with him during this and they took a female airman with them as a possible host. Another battle occurs on Abydos where Apophis took two Abydonians as possible hosts and one becomes host to Amonet, while the other becomes host to his son Klorel. SG-1 and SG-2 followed him to Chulak where Teal'c joins the side of the Tau'ri as he saw them as the only hope for freeing his people, the Jaffa. Teal'c joined SG-1 alongside Colonel O'Neill, Dr. Daniel Jackson and Captain Samantha Carter as the team's new fourth member.

Apophis' attempted attack (1998)
Around a year later, after several skirmishes with SG-1 and Earth, Apophis launched an attack on Earth with two ships in an effort to destroy it once and for all. SG-1 managed to board his ship through the Stargate and destroy both of them with C-4 and help from Bra'tac although Apophis manages to escape through the Stargate. He looses his army with this and most of his power. He later ended up escaping from Sokar and came to Earth asking for asylum hoping that Sokar would destroy it for him since he was there. He died on Earth and his body is sent through the Stargate back to Sokar, stopping Sokar's attack.

SG-1, except for Teal'c, was later captured by Hathor. She tried to trick them into believing that they were in the future in order to get information out of them, but they saw through her deception and escaped, although she recaptured them. Teal'c and Bra'tac gathered a force of Jaffa to rescue them and General Hammond joined the rescue himself. O'Neill killed Hathor and the rescue team took out her Jaffa.

Later on Earth the former System Lord Seth was tracked down and killed by Captain Carter. The System Lords also plotted another, bigger attack on Earth using their combined might so the Asgard stepped in to include Earth in the Protected Planets Treaty which would protect it from further attack by the System Lords. Yu, Cronus and Nirrti came to Earth to negotiate and despite Nirti's attempts to sabotage the peace treaty, it was passed and the Earth was saved again.

New Strategies (1998-1999)
Because of the loss of two motherships and most of his Serpent Guards, Apophis' standing among the System Lords was considerably weakened. Apophis attempted to take revenge on Teal'c by brainwashing his son Rya'c and using him to infect Earth with a deadly plague. Apophis captured Rya'c and by the time Teal'c returned to Chulak, Apophis had brainwashed him into publicly denouncing his father. For something he said, Teal'c thought his son was only playing along. SG-1 rescued him and brought him and Drey'auc back to Earth. Once there, however, they discovered Rya'c really was brainwashed and conditioned to kill himself and everyone on Earth. Teal'c had to shoot him with the zat to break the conditioning. Rya'c went to live with his mother in the Land of Light after that.

Apophis also impregnated Sha're, Daniel Jacksons wife and host of Amonet, with a boy. Known as Shifu, he was a Harcesis, a human child of Goa'uld parents who possessed all Goa'uld knowledge, and was hunted for it. He fathered it with the hopes of using the child as a future host to himself. Oma Desala cared for Shifu after Sha're's death on the planet Kheb for his infant years.

Within a year, Apophis' forces were nearly depleted, suffering losses to both Heru'ur and Sokar. Fleeing from Sokar's forces, Apophis demanded sanctuary among the Tau'ri, at the very least hoping to kill the Tau'ri with him. However, the Tau'ri soon turned Apophis over to Sokar, who sent him to Ne'tu. Apophis managed to assume the guise of Na'onak, First Prime of Bynarr, Lord of Ne'tu.

The Rise and Fall of Apophis (1999-2001)
In 1999, Sokar made his presence officially known again among the System Lords, by making Apophis a prisoner on Netu, as well as engaging in a war with Heru'ur. Within a year, however, he was prepared to launch a massive attack against the System Lords, which would have put him in control of the Goa'uld Empire.

Realizing how dangerous that would be, the Tok'ra planned to destroy Netu. SG-1 arrived attempting to rescue Jacob Carter from Netu and to destroy the planet. After a first failed attempt, Teal'c sent the Tel'tak to Vorash, where Aldwin sent a bomb to Netu. When the bomb was activated and sent to Netu, the core would overload and destroy the moon 12 minutes later. Meanwhile Apophis led a rebellion on Netu after killing his former master, Bynarr. He tortured SG-1, trying to learn information to make Sokar spare his life. While he greatly enjoyed torturing SG-1, all he learned was that the Tok'ra were based on Entac. Planning to kill Sokar once he was in his presence, Apophis ringed aboard Sokar's mothership. However, Sokar had already conquered Entac, and there were no Tok'ra there. Sokar ordered Apophis to be killed, but soon Netu's core began to destabilize. Apophis killed Sokar's guards and rigned to Delmak, Sokar's homeworld. There, he claimed that he had killed Sokar, and took Sokar's forces for his own, while SG-1 and the Tok'ra were able to escape. Sokar's mothership was destroyed in Netu's explosion, killing Sokar.

Less than a year later, the SGC learned of Apophis' survival, after he launched an attack on Chulak, searching for the Harcesis, and later launched an attack on Kheb. He also built a new flagship, more powerful than the standard Ha'tak, and began to build a new type of mothership. The later was destroyed when SG-1 sabotaged the construction facility.

Apophis later came close to forge an alliance with his former enemy Heru'ur, but the Tok'ra and SG-1 were able to sabotage it, hoping to start a war between the two and decimating their power. However, Apophis had brought a cloaked fleet with him, and was able to destroy Heru'ur's mothership, killing him. Absorbing Heru'ur's forces into his own, Apophis was easily the most powerful System Lord within the Goa'uld Empire. With Apophis' fleet on the way to attack the Tok'ra base on Vorash, Samantha and Jacob Carter devised a bold trap: they intended to cause Vorash's sun to supernove, hoping to destroy most of Apophis' fleet and hopefully even Apophis himself. The plan worked, but Apophis survived, capturing Teal'c in the process. Apophis' mothership and a ha'tak that SG-1 had acquired after they had killed Cronus was thrown to another galaxy, one which the Replicators were in.

The Replicators destroyed Apophis' mothership, though Apophis was able to escape along with a bodyguard and Teal'c, who had been brainwashed into believing he was his First Prime (very similarly to how he had brainwashed Rya'c earlier). Apophis and his forces were able to take over the ha'tak, but a single Replicator had managed to sneak aboard. The Replicators took control of the Ha'tak, flying to Delmak at incredible speeds. Though SG-1 and Jacob were able to escape, taking Teal'c with them, Apophis was trapped in the pel'tac. SG-1 was able to disable the sublight drives, causing an uncontrolled re-entry into Delmak. Apophis was killed in the crash.

His death, following the death of Cronus a few days earlier, caused the System Lords to enter into a war that the Tok'ra hoped would last for years. However, it helped Tanith and Zipacna become formidable players in the "new order" forged. Worse, it also accelerated events which resulted in the return of Anubis.

The Return of Anubis and Reign of Ba'al (2001-2005)
With the three dominant System Lords dead, the remaining System Lords began a fierce war among themselves to dominate the others. However, they also began to experience a new threat among themselves, as one enemy attacked using only ships, and never with Jaffa. The System Lords eventually called the High Council to deal with the issue. The recently returned Osiris also arrived, revealing the identity of their enemy&mdash;Anubis. Osiris sent gave the others two options: restore Anubis to the state of System Lord, or place themselves at the "mercy" of Anubis. Despite the objections of Lord Yu, Anubis was restored to his former status in promising for destroying Earth.

What they didn't know was that Anubis had achieved Ascension, only to be cast down by the Others, leaving him unable to use significant powers, but with a great deal of knowledge of Ancient technology.

At the same time, Anubis ordered Zipacna to launch an attack on Revanna, seeking the symbiote poison. This objective failed, but resulted in wiping out virtually all the Tok'ra on the base. After the deaths of Apophis and Cronus, Anubis began to make his presence felt among the Goa'uld again. He brought in many underlords to serve him, such as discredited Goa'ulds like Osiris and Thoth, and newer Goa'ulds such as Zipacna and Tanith. He used his advanced shield technology to force the Tollans into providing new phasing weapons for him so he could bomb the SGC, but the Tollan Narim destroyed them, causing Anubis to annihilate Tollana.

Finally, Anubis felt secure enough to challenge the Asgard. His shields and modifications to staff cannons allowed him to fight the Asgard in limited numbers. He captured the commander of the ship sent to stop him, Thor. Using a mind probe, Anubis became determined to find out all of the Asgard's secrets. But SG-1 rescued him and three arriving O'Neill-class ships forced him to retreat. But not before Anubis gained knowledge of Asgard beaming and hologram technology. Convinced he no longer needed to fear them, Anubis used a Stargate destroyer in an attempt to destroy Earth. He appeared to the SGC as a hologram, pronouncing their doom. But Colonel Jack O'Neill used the prototype X-302 to transport the Beta Gate into space and simultaneously, the attacking weapon was also destroyed by Rebel Jaffa. Fearing the reprisals of the System Lords, Anubis built a new mothership carrying a powerful superweapon. He traveled to Abydos to obtain the Eye of Ra, one of the remaining Eyes he had yet to collect. SG-1 found the artifact before he could claim it. An Ascended Daniel Jackson bargained with Anubis for the Eye in exchange for Abydos' safety, mainly because the System Lords had him cornered. But once the Goa'uld received his prize, his vessel single-handedly destroyed an entire fleet of System Lord motherships with the combined powers of the Eyes. He then planned to annihilate Abydos, knowing that Jackson would try to stop him and Oma would interfere, preventing Daniels actions. Without resistance, he destroyed the planet, but not before its population ascended, also with the help of Oma Desala. Months later, SG-1, with the help of a de-ascended Jackson, plotted to destroy Anubis' mothership. Jackson and Jonas Quinn located a critical weakness while O'Neill and Samantha Carter used an F-302 to bypass its shields and strike, allowing the System Lords to destroy the vessel. Unfortunately, only half of the plan was completed, for Yu, due to age-induced senility, called off the attack. Anubis, despite his loss, gained a new prize in the form of a captured Jonas. Probing his mind, Anubis learned the location of his homeworld Langara and its naquadriah deposits. With his ship appearing over the capital Kelownan city, Anubis took control of the planet and began to strip it for naquadriah to rebuild his planet destroyer. But his research proved insufficient, for naquadriah proved too unstable to compensate. His Jaffa managed to locate a crystal containing research on the mineral that would have allowed him to use the naquadriah but it was retrieved by SG-1. Worse for him, the System Lords, under Baal's command, destroyed his ship, forcing him to flee.

Sensing the threats of the Jaffa Rebellion, Anubis began researching a way to create a new footsoldier. Using the technology of the Ancients' healing device and Jonas Quinn's memories of Egeria, Anubis engineered an army of nearly unstoppable Kull warriors. The Kull warriors were far superior to the Jaffa, and Anubis quickly regained much lost ground. When he learned of an Ancients' repository of knowledge on P3X-439, he sent a force to secure it. However, Jack O'Neill managed to download the knowledge into his mind. Believing the Tau'ri possessed Ancient technology and the location of Atlantis, he attacked Earth with his fleet. He communicated with the United States president, demanding his surrender, with the latter promising a fight to the bitter end. Anubis later tried to trick SG-1 into thinking he got to Atlantis first, but O'Neill, with the Ancient knowledge, easily saw through the illusion. Anubis was apparently destroyed by the drone weapons that SG-1 found in the Antarctic outpost buried under the ice of Antarctica.

However, his formless essence survived the explosion of his mothership. He hitched a ride on a Russian space craft, possessing the body of a cosmonaut and returning to Earth. Leaping from person to person he made his way to Stargate Command, where he managed to escape through the Stargate in the body of the dying Russian officer Alexi Vaselov&mdash;but he found himself frozen near the gate on an ice-covered planet, trapped.

The End of the War (2005)
Being half-ascended, Anubis returned, and became the power behind Ba'al's rise to power. When the Replicators began their invasion of the Milky Way, Anubis ordered his fleet to attack them head on, allowing the Replicators to acquire materials. When the Rebel Jaffa took Dakara, Anubis ordered Ba'al to take the fleet to reclaim the planet at all costs. Knowing that Anubis intended to use the superweapon on Dakara to destroy all life in the Milky Way galaxy, Ba'al worked with Samantha and Jacob Carter to modify the weapon to destroy the Replicators. Undaunted, Anubis took the remaining Kull warriors in an attempt to carry out his plan.

He devised a trap to draw the fleet the Free Jaffa Nation had assembled after the Battle of Dakara. Bra'tac and Teal'c proposed that they unify the Jaffa by attacking Tartarus, Anubis' stronghold and the planet where he was manufacturing the Kull warriors. However, Anubis had already abandoned the planet, and his army began an assault on Dakara. When he entered a midpoint between ascension and human existence to mock Oma Desala, he found Daniel Jackson, also at the midway point. He took the persona of Jim, a patron in the Astral Diner, mocking Oma and subtly pointing Jackson in the direction of Oma as the cause of Anubis' ascension. When Jackson realized that Jim was Anubis, he attempted to attack the System Lord, but lacked the power to even touch him. By this point, the Kull warriors had secured control of Dakara, and Anubis was in place to destroy life in the Milky Way. However, he was stopped by Oma Desala.

Inspired by Daniel's actions, she engaged Anubis in eternal struggle. Neither one can win, which prevents Oma from helping others to ascend, but Anubis would be forced to concentrate on fighting her back, also preventing him from ever harming the galaxy again. With a cry of rage and fear, Oma ascends Anubis to the higher planes and attacks him (because Oma would have been prevented from attacking a lower being,) ending his reign of terror over the galaxy and leading to the fall of the Goa'uld Empire.

Aftermath (2005-2008)
With the defeat at Dakara, the Goa'uld's image as gods were utterly destroyed. The Jaffa began rebelling en mass, heading to Dakara to pledge allegiance to the new Free Jaffa Nation.

Bereft of power, and a fugitive of the Free Jaffa Nation, Ba'al fled to Earth, and took control of the Trust. To throw off the Free Jaffa, Ba'al created a series of clones and allowed one of them to be captured and killed by Gerak. Ba'al also attempted to a new plan of conquest: by stealing Stargates and cutting them off from the rest of the network, he intended to activate the Dakara superweapon and destroy all life in the galaxy, causing the Ori, who had recently learned of human life in the Milky Way, to lose interest in the galaxy. SG-1 sabotaged his efforts.

Eventually, Ba'al learned of the Sangraal. Desiring a weapon that could neutralize the Ancients and the Ori, Ba'al began searching for the Sangraal. He was forced to work with SG-1 and Adria, the leader of the Ori Army. However, the Ori found the planet they were on and took the Sangraal. SG-1 later sent it through to the Ori Home Galaxy.

Hoping to end the Ori invasion, Ba'al captured Adria and took here as a host. He also killed his clones, hoping to cover his tracks. Lieutenant Colonel Cameron Mitchell killed Ba'al during the capture of Adria, and the symbiote placed in her was soon removed.

Despite these deaths, both the real Ba'al and at least one clone survived. The clone was ultimately tracked down through its tracking device and the Tok'ra planned to remove the symbiote from the host to kill it. The symbiote was successfully extracted from the Ba'al clone and died, finally killing the last Ba'al. His host survived the extraction, however, and Vala offered to help him cope. Also the real Ba'al is killed by an alternate Mitchell in 1939 before he can change time, killing the last remaning System Lord. (see - Alternate Timeline)

Alternate Timeline
''Ba'al travelled back to 1939 and sends the ship carrying the Stargate to America to the North Pole and heads out into the galaxy to create his own empire. Mitchell doesn't exist, Carter was dead here and the Stargates were never found. Carter, Mitchell and Daniel end up here due to being in transit in the Stargate at the time of the changes and are thus protected from them. Daniel loses his leg due to frostbite and the team are not allowed to travel through the Stargate and set things right and are forced to lead normal lives for a year. The gate in the Antarctic was found, but was not figured out how to use. Meanwhile the Russians find and take the Gate from the North Pole. Ba'al launches an attack with Teal'c as his First Prime and Vala (as Qetesh) as his queen. He commanded all of the System Lords and with their combined forces, comes after Earth believing to be unaware of the Goa'uld as he doesn't know SG-1 was there.

He attempted to present an air of benevolence to the President by calling him on the phone and setting up a time to meet face to face, but was killed by Qetesh before he could finish. He also had the Gate in Antartica and the weapons platform destroyed under Qetesh's forcing before his death leaving Earth with no real defences. Qetesh planed to use the time travel device to gain power herself, but was thwarted by Daniel, Teal'c, Carter, Mitchell and two other Jaffa who got to Praxyon before she did through the Gate that the Russians found and use the time travel device to set things right, but as Teal'c dies, he killed her with a grenade. The timeline was erased when Mitchell, in 1939, sets an ambush and killed Ba'al and his soldiers before they can change time.''
