Synopsis
The Grunt Rebellion is an event in the history of the empire of the Covenant. It occurred when the growing Grunt population put pressure on the Jackal population which they shared their habitat with. Apparently, the overwhelming Grunt population forced many of the Jackals to relocate, killing many of their eggs and forcing the Jackal birth rate to decline. In an effort to exact revenge, one of the Jackals poisoned the Grunts' infusion resources, which escalated the conflict between the two species. After the Prophets failed to respond to it (Due to the High Council rejecting the Minister of Fortitude's request to have further investigation done), it escalated into a short, but aggressive conflict, forcing the High Council to elect an Arbiter, but the conflict only ended when the Grunt's homeworld was almost glassed by the Covenant fleet.
