What happened at the Crossing of the Rubicon

The Rubicon was a small river in northern Italy marking the boundary of the province Caesar governed. Roman law forbade a general from bringing troops into Italy proper. When the Senate, urged on by Pompey and his allies, ordered Caesar to relinquish his command, he chose defiance instead. In January 49 BCE he led the Thirteenth Legion, part of his larger army, across the river into Italy. The act was treason under Roman law and made armed conflict unavoidable. Ancient writers say Caesar declared the die was cast. The ensuing civil war ended senatorial rule and paved the way for Caesar's dictatorship and, later, the empire.
