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 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. After Truth learned the location of the human homeworld, he secretly amassed a fleet of over five hundred warships, entirely commanded by the Jiralhanae, at the command-and-control station Unyielding Hierophant. However, this station and fleet was destroyed by a group of SPARTAN-IIs who learned of its purpose; putting a temporary halt to Truth's plan.[3]

Soon after, 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, and 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 still 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 forces, 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 Delta Halo, Truth's move remained a secret from the rest of the Covenant. Regret, who would arrive at Delta Halo some time before High Charity and the rest of the Covenant, would serve yet another purpose for Truth; the final stage in his plan.[3]

Conflict erupts

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' 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 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 fleets to the Jiralhanae. Once enough Jiralhanae were in place, Truth instigated the war by secretly ordering the assassination of many 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 Halos and the Great Journey. Their disillusionment changed their goal from reforming the purity of the Covenant to actively fighting against it.

During the original conflicts aboard High Charity, the species of the Covenant took distinct sides. Loyalists followed the Prophets and included Jiralhanae, Kig-yar, and Yanme'e. Separatists primarily consist of the Sangheili, with Mgalekgolo and most Unggoy also breaking away initially.

Sangheili-human alliance

The shaky alliance between the separatists and their former foes, the humans, 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, 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.[4] 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 death of the Prophet of Truth.

The devastated 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 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.

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 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 war against the Arbiter and his allies for collaborating with humanity.[5]

With Truth dead, High Charity destroyed, and the Ark essentially lost after Installation 04B's firing, the remaining loyalist forces remained active in at least some form, rebuilding their tattered strength to continue their war of conquest.[6] 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.[7]

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.
