Treaty of Voi

The Treaty of Voi was the peace treaty ratified by the United Nations Space Command and the Sangheili-led Covenant Separatists that ended the state of war between these two sovereign powers, marking the formal cessation of the 28-year-long Human-Covenant War. Signed into effect at the eponymous African city of Voi on March 3, 2554, the Treaty of Voi confirmed the armistice between the UNSC and Sangheili forces and inaugurated a new era of political, economic, and military collaboration between the UNSC and the Sangheili-led remnants of the Covenant, under which "foundry worlds" such as Dashan were anointed together by both governments, and joint colony worlds such as Calliope were established. Thereafter, both the UNSC and Sangheili militaries also embarked on a genocidal campaign to sanitize Jiralhanae space, leading to the fall of Doisac and the formation of the Jiralhanae Demilitarization Assistance Force — the joint UNSC/Sangheili military armada responsible for continued reconnaissance for Jiralhanae renegade fleets in the Covenant Borderlands and stability operations on occupied Jiralhanae worlds.
The Treaty of Voi would be grievously challenged scarcely five months after its ratification in August 2554, with the outbreak of the Memory Crisis in the Carinae-312 System, which for over a month set into motion an inflammatory state of conflict between UNSC forces and those of the Sangheili — hundreds of thousands of UNSC and Covenant forces were killed in open theater warfare on Carinae-312D until that conflict too was defused.
