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.
