A single engagement, the , took place beyond the galactic disc itself, and is widely regarded by historians as one of the most decisive battles of the war.
The war was instigated by the Covenant, whose discovered that humans were directly descended from the Forerunners, a hyper-advanced extinct species whom the Covenant venerated. In order to keep the Covenant intact, war was declared against humanity, and over the next decades the Covenant repeatedly defeated humanity across hundreds of colony worlds, slowly moving closer to Earth itself and leaving only dead worlds in its path.

The official end of hostilities came on March 3, 2553, when the Covenant Separatists and the UNSC signed the Interim Coalition Agreement aboard UNSC Aegis Fate.

The war, the most deadly and damaging in the modern histories of both Humanity and the Covenant, cost the lives of nearly twenty five billion sentient beings, with a staggering twenty three billion of these being Human deaths.
