Quintus Sertorius (c. 126 BC – 73 or 72 BC) was a Roman general and statesman who led a large-scale rebellion against the Roman Senate on the Iberian Peninsula. Defying the regime of Sulla, Sertorius became the independent ruler of Hispania for most of a decade until his assassination.
Sertorius first became prominent during the Cimbrian War fighting under Gaius Marius, and then served Rome in the Social War. After Lucius Cornelius Sulla blocked Sertorius' attempt at the plebeian tribunate c. 88 BC, following Sulla's consulship, Sertorius joined with Cinna and Marius in the civil war of 87 BC. He led in the assault on Rome and restrained the reprisals that followed. During Cinna's repeated consulships he was elected praetor, likely in 85 or 84 BC. He criticised Gnaeus Papirius Carbo and other Marians' leadership of the anti-Sullan forces during the civil war with Sulla and was, late in the war, given command of Hispania.
