Vindex

Gaius Julius Vindex was a Roman governor in the province of Gallia Lugdunensis (modern Brittany, Normandy and the area around Paris) who rebelled against the Emperor Nero in 67 AD. Although he was defeated and killed by the loyal general Lucius Verginius Rufus in 68, Vindex' rebellion was the start of a series of uprisings against the tyrannical emperor which resulted in Nero's deposition and suicide that summer, and the civil war of the Year of the four emperors.
