The Great War

The Great War, a name often applied to the Human-Covenant War, covers historical events during that conflict from 2525 up to its conclusion in 2552. As the war marked the intersection of the two civilizations' timelines, both human and Covenant-related events are listed; for prior events, Human history and Covenant history should be used. The Great War is followed by the Reconciliation Era, beginning in 2553.
