(I've removed some of the idealistic nonsense about the Schism from the pre-343 Industries era. The human-Sangheili alliance was not a simple case of, "Everybody forgave each other, shook hands, and went home happy.")

Even long before the start of the Great Schism, the [[Prophet of Truth|High Prophet of Truth]] had plans of replacing the Sangheili with the Jiralhanae, as he saw them as more willing and unquestioning pawns, while he distrusted the Sangheili, doubting their reliability and loyalty. However, he kept these schemes strictly to himself, and waited until the time was right.

Soon after, the [[Prophet of Regret|High Prophet of Regret]] made a move Truth did not expect: having discovered a significant [[Forerunner]] [[The Portal|artifact]] on Earth on his own, but unaware of the fact it was humanity's homeworld, he took [[Fleet of Sacred Consecration|a fleet]] of fifteen ships to Earth.

After the Prophet of Regret was killed by [[John-117]], the two remaining [[Hierarchs]], most notably the Prophet of Truth, reorganized Covenant society. Claiming that the Sangheili could no longer protect the Prophets due to Regret's death, they replaced the [[Sangheili]] with the [[Jiralhanae]] as the Prophets' [[Covenant Honor Guard|protectors]]. The Sangheili viewed this as a violation of the principle that the Covenant had been founded upon and threatened to resign from the [[High Council]]. They also argued that if Truth had not withdrawn the [[Type-52 Troop Carrier|Phantoms]] that had been en route to Regret's location, the Prophet's death would have been prevented and the "Demon" would have been killed instead.

However, Truth further demoted the Sangheili by giving command of their [[Covenant fleet]]s to the Jiralhanae. Once enough Jiralhanae were in place, Truth instigated the war by secretly ordering the assassination of many [[councilor|ruling]] Sangheili. Truth also freed all of the Jiralhanae prisoners and pardoned them after release. This was perceived as a Jiralhanae insurrection against the Covenant to the Sangheili, the [[Mgalekgolo]] and many [[Unggoy]]. Loyalist factions were led to believe it was a Sangheili revolt. After the assassination of the Sangheili councillors, war broke out on High Charity, with the two sides polarizing quickly. However, this was at first a debate over orthodoxy and leadership. The true split occurred when the Sangheili discovered the truth about the [[Halo Array|Halos]] and the [[Covenant religion|Great Journey]]. Their disillusionment changed their goal from reforming the purity of the Covenant to actively fighting against it.

The shaky alliance between the [[Covenant separatists|separatists]] and their former foes, the [[human]]s, was forged entirely out of necessity. The UNSC forces were on the defensive, and they had two common enemies that wished for their extinction: the Covenant and the Flood. The alliance of circumstance was forged in the control room of [[Delta Halo (level)|Delta Halo]], when Johnson and the Arbiter were coerced to unite in order to prevent Tartarus activating Delta Halo and firing the Halo Array, which would have killed every sentient being in the galaxy, including himself and the rest of his race, while he, and the rest of the Covenant Loyalist's, still believed the array would only start the Great Journey.<ref>'''[[Halo 2]]''', campaign level, ''[[The Great Journey]]'' Final Cutscene</ref> However, the Arbiter persuaded the rest of the Sangheili to join the humans. While the two factions experienced some friction because their alliance is based on the ''the enemies of my enemies are my friends'' concept instead of good political relationships they learned to work with one another for their mutual survival.

The devastated [[United Nations Space Command|UNSC]] [[fleet]] in [[Earth]]'s space were glad to accept the help of the superior separatist warships. The Sangheili understanding of enemy equipment and Covenant's combat tactics proved invaluable in the [[Battle of Installation 00]], where a fleet three times larger than that sent by the Sangheili was completely destroyed by the smaller force. Recurrently the heroes of battle, the Arbiter and the [[John-117|Master Chief]] fought alongside one another many times in the desperate and long conflict. Together the two made an incredible team and the [[Prophet of Truth]] was finally killed by the Arbiter with the Master Chief deactivating the Halo Array.
On November 17, the devastated [[UNSC Home Fleet]] attempted a last-ditch assault on the Prophet of Truth's Forerunner [[dreadnought]], which had integrated with the artifact that Regret had discovered nearly a month prior. This attack failed and a [[Unidentified Flood-captured battlecruiser|Flood-controlled battlecruiser]] crashed in [[Voi]] only moments after Truth's fleet entered the portal generated by the artifact. However, the separatist [[Fleet of Retribution]], led by [[Shipmaster]] [[Rtas 'Vadum]], arrived in pursuit of the cruiser; as the fleet glassed the city and its environs, the Sangheili and UNSC agreed to follow Truth beyond the portal.


Later, when the Chief destroyed the Flood-controlled ''[[High Charity]]'' and the Ark was severely damaged when he fired the new Halo ring created above the Ark which also destroyed the Flood. [[Shipmaster]] [[Rtas 'Vadum]] stated that Truth's fleet was destroyed at the battle over the Ark. Had any of them survived on the Ark or in the ruins of their fleet, they were either taken by the Flood or killed when the unfinished [[Installation 04B]] fired and destroyed itself and heavily damaged the Ark.

The joint Sangheili-UNSC fleet arrived at the Halo Array's control center, [[Installation 00]], on December 11. During the [[Battle of Installation 00|ensuing battle]], the separatist fleet completely destroyed their Covenant counterpart, despite the latter's three-to-one numerical superiority. Separatist forces later helped SPARTAN-117 disable the shield generators protecting the installation's [[Citadel]], in which the Prophet of Truth was hiding. The Master Chief and the Arbiter entered the Citadel and fought through what remained of Truth's personal guard. After reaching the control panel they discovered that the Hierarch had been infected by the Flood; as the Prophet slipped in and out of lucidity, 'Vadam stabbed him in the back. The Flood-controlled High Charity was destroyed shortly thereafter, effectively dissolving the Covenant.


The Arbiter's presence at memorial services for the Master Chief indicated that in the wake of victory, Sangheili and humans remained friendly to one another as they both had made tremendous sacrifices in order to stop Truth and his forces, as well as the Gravemind and the Flood. However, the peace between the two species remained on shaky ground, with many Sangheili insurgents, rallied together by the [[Servants of the Abiding Truth]], still despising humanity and even openly inciting [[Sangheili civil war|war]] against the Arbiter and his allies for collaborating with humanity.<ref>'''Halo: The Thursday War'''</ref>

Template:Battle Infobox The Great Schism,[1] also known as the Great Betrayal among the Sangheili,[2] was a major conflict between the forces loyal to the Covenant and an association of separatists, which split apart between October 2552 and November 2552. During the Schism, three major factions fought for victory: humans and their Sangheili-led separatist allies; the remnants of the Covenant, led by the San 'Shyuum and the Jiralhanae; and the Flood, which took over the Covenant holy city of High Charity in an effort to assimilate the other warring factions.

History

Background

"We are strong, Kig-Yar. That is why we sit at the right hand of the Prophets."
— Thel 'Vadamee

"One day that shall pass."
— Reth

Even long before the start of the Great Schism, the High Prophet of Truth had plans of replacing the Sangheili with the Jiralhanae, as he saw the latter as more willing and unquestioning pawns, while he distrusted the Sangheili, doubting their reliability and loyalty. However, he kept these schemes strictly to himself and waited until the time was right to implement them. After Truth learned the location of the human homeworld, he secretly amassed a fleet of over five hundred warships, commanded entirely by Jiralhanae, at the command-and-control station Unyielding Hierophant. In September, this station and the fleet were destroyed by a group of SPARTAN-IIs who learned of its purpose shortly before the invasion could commence. This put a temporary halt to Truth's plans.[3]

On October 20, the High Prophet of Regret made a move Truth did not expect: having discovered a significant Forerunner artifact on Earth on his own, but unaware of the fact it was humanity's homeworld, he took a fleet of fifteen ships to Earth. Immediately after Truth learned of this, he sent the remnants of the fleet he had amassed to Earth; he gave his Jiralhanae troops orders to forcibly overtake the Sangheili in command of the remaining forces on and above Earth. When Regret retreated from Earth, his Sangheili-led ships in orbit continued to engage the UNSC, but now without a leader. Only moments after, the Jiralhanae forces within the fleet and on the ground killed any remaining Sangheili, as Truth had ordered. They continued to hold New Mombasa until the reinforcements sent by Truth arrived. As High Charity and the rest of the Covenant fleet were now on their way to the newly discovered Halo Installation 05, Truth's scheme remained secret from the rest of the Covenant. Regret, who would arrive at Delta Halo weeks before High Charity and the rest of the Covenant, would serve yet another purpose for Truth: the final stage in Truth's plan.[3]

Conflict erupts

After the Prophet of Regret was killed by SpartanJohn-117 on November 2, the two remaining Hierarchs reorganized Covenant society. Claiming that the Sangheili could no longer protect the Prophets due to Regret's death, they replaced the Sangheili with the Jiralhanae as the Prophets' protectors. The Sangheili viewed this as a violation of the principle that the Covenant had been founded upon and threatened to resign from the High Council.

However, Truth further demoted the Sangheili by giving command of their fleets to the Jiralhanae. Once enough Jiralhanae were in place, Truth instigated a pogrom by secretly ordering the assassination of many Sangheili Councilors. Truth also freed all Jiralhanae prisoners and pardoned them after release. This was perceived as an insurrection against the Covenant to the Sangheili, as well as many Mgalekgolo and Unggoy. Loyalist factions were led to believe it was a Sangheili revolt. After the assassination of the Councilors, war broke out on High Charity, with the two sides polarizing quickly. However, this was at first a debate over orthodoxy and leadership. The true split occurred when the Sangheili discovered the truth about the Halos and the Great Journey. Their disillusionment changed their goal from reforming the purity of the Covenant to actively fighting against it the following day. Around this time, Truth left the Prophet of Mercy to die at the hands of the Flood, solidifying his place as the autocrat of the Covenant.

At the front lines of the original conflict aboard High Charity, the species of the Covenant took distinct sides. Loyalists followed the Prophets and included all but a few Jiralhanae,[4] most Kig-Yar and Yanme'e, some Unggoy, and a minority of the Mgalekgolo. Separatists forces consisted of the Sangheili, most Mgalekgolo, and many Unggoy.

Sangheili-human alliance

The shaky alliance between the separatists and their former foes, the humans, was forged entirely out of necessity. Both sides had two common enemies that wished for their extinction: the Covenant and the Flood. This alliance of circumstance was forged in the control room of Installation 05, when Sergeant Major Avery Johnson and Arbiter Thel 'Vadamee united to prevent Tartarus from activating Delta Halo and firing the Halo Array.[5] The Arbiter persuaded many Sangheili, (though far from all of them),[6] to ally with the humans.

The death of the Prophet of Truth.

On November 17, the devastated UNSC Home Fleet attempted a last-ditch assault on the Prophet of Truth's Forerunner dreadnought, which had integrated with the artifact that Regret had discovered nearly a month prior. This attack failed and a Flood-controlled battlecruiser crashed in Voi only moments after Truth's fleet entered the portal generated by the artifact. However, the separatist Fleet of Retribution, led by Shipmaster Rtas 'Vadum, arrived in pursuit of the cruiser; as the fleet glassed the city and its environs, the Sangheili and UNSC agreed to follow Truth beyond the portal.

The Ark

The joint Sangheili-UNSC fleet arrived at the Halo Array's control center, Installation 00, on December 11. During the ensuing battle, the separatist fleet completely destroyed their Covenant counterpart, despite the latter's three-to-one numerical superiority. Separatist forces later helped SPARTAN-117 disable the shield generators protecting the installation's Citadel, in which the Prophet of Truth was hiding. The Master Chief and the Arbiter entered the Citadel and fought through what remained of Truth's personal guard. After reaching the control panel they discovered that the Hierarch had been infected by the Flood; as the Prophet slipped in and out of lucidity, 'Vadam stabbed him in the back. The Flood-controlled High Charity was destroyed shortly thereafter, effectively dissolving the Covenant.

Shipmaster 'Vadum evacuated the remaining separatist and human forces after the holy city's destruction. Seemingly, only his flagship, Shadow of Intent, remained. Any remaining Covenant forces were killed when Halo Installation 04B was activated and the Ark was severely damaged by the debris; the activation also ended the immediate threat of the Flood. The Master Chief, the Arbiter, and the AI Cortana had escaped on the frigate Template:UNSCship, which was split in half when their escape portal closed too early.

After the Human-Covenant War

Though 'Vadam sought a lasting peace with humanity, many of the Sangheili were not willing to suddenly end their war with humanity. Many Sangheili insurgents, rallied together by the Servants of the Abiding Truth, incited war against the Arbiter and his allies for collaborating with humanity.[7] With Truth dead, High Charity destroyed, and the Ark nearly destroyed after Installation 04B's firing, some of the remaining loyalist forces tried to rebuild their tattered strength to continue their war of conquest.[8] Even though the Jiralhanae eventually collapsed into various civil wars, they still posed enough of a threat that Sangheili commanders kept up the offensive against them for at least another six years, even as they continued to lose irreplaceable warships and the war continued with no end in sight.[9] Jul 'Mdama, a former member of the Servants of the Abiding Truth, eventually reformed the Covenant, with the Sangheili again serving as its leadership caste.

Trivia

  • A "schism" is a division within a religious sect or denomination. The term "Great Schism" is sometimes used to describe real-world internal religious debates, most notably the East-West Schism, which led to the establishment of the Eastern Orthodox Church, and the Western Schism, which caused a split within the Roman Catholic Church.
  • In Halo: Contact Harvest, the Prophet of Truth foreshadows the Great Schism, noting that if the Sangheili ever separated from the Covenant, the entire government would collapse.[citation needed]
  • According to the Bestiarum, the Unggoy were too indecisive to continue the rebellion and the true political motivation of the Mgalekgolo, if any, remained a mystery.
  • In Halo 3: ODST, it is implied that the Office of Naval Intelligence was aware of internal conflict within the Covenant from early on. During the level Tayari Plaza which takes place on October 20, Buck asks Dare about the Sangheili bodies lying around the city, as they appear to have been killed by the Jiralhanae; Dare responds that said information is classified.
