List of Roman civil wars and revolts

But with the Crisis of the Roman Republic (134–44 BC), a period of considerable political instability began.

Political instability returned to the Empire with the Crisis of the Third Century (235–284 AD), which saw at least 26 civil wars in just 50 years as usurpers sought the imperial throne.

The overthrow of the last Western Roman emperor in AD 476 by the Germanic king Odoacer marked the final civil war or revolt, as well as the end of the Western Roman Empire.

For example, historians Lange & Vervaet suggest that the crisis after Caesar's assassination might be better understood as an internal emergency.

Conversely, some revolts on this list may be properly considered to be civil wars, but were not referred to as such by Roman chroniclers.
