Sertorius

Quintus Sertorius (c. 123–72 BC) was a politician and a soldier of the Roman Republic who turned rebel after being outlawed. He fought in four major wars; the Cimbrian War, the Social War, Sulla's second civil war and the Sertorian War against the faction led by Lucius Cornelius Sulla. During the Second Civil War he was part of the popular faction of Cinna and Marius and upon their demise he was proscripted (outlawed). Sertorius was a brilliant military commander which was shown most clearly during the Sertorian War (80-72 BC) in the Iberian peninsula. There he defeated his opponents on many occasions and, at one stage, even gained control over the entire peninsula. He was never decisively defeated and remained a thorn in the Republic's side until his assassination in 72 BC.
