Civil war

Civil war, armed conflict between rival factions within a single state, is a recurring cause of imperial decline. Succession disputes, regional rebellions and rivalry among generals drained resources, divided armies and invited foreign intervention. Examples include the late Roman Republic's civil wars, the fitnas that divided the Rashidun and Umayyad caliphates, the dynastic wars of the Seleucid Empire and the Kongo Empire's civil wars after 1665.
