Civil war resulted, and Caesar's victory in the war put him in an unrivalled position of power and influence.Īfter assuming control of government, Caesar began a programme of social and governmental reforms, including the creation of the Julian calendar. Caesar refused the order, and instead marked his defiance in 49 BC by crossing the Rubicon with the 13th Legion, leaving his province and illegally entering Roman Italy under arms. With the Gallic Wars concluded, the Senate ordered Caesar to step down from his military command and return to Rome. These achievements granted him unmatched military power and threatened to eclipse the standing of Pompey, who had realigned himself with the Senate after the death of Crassus in 53 BC. Caesar became the first Roman general to cross both the Channel and the Rhine, when he built a bridge across the Rhine and crossed the Channel to invade Britain. Caesar's victories in the Gallic Wars, completed by 51 BC, extended Rome's territory to the English Channel and the Rhine.

Their attempts to amass power as Populares were opposed by the Optimates within the Roman Senate, among them Cato the Younger with the frequent support of Cicero. In 60 BC, Caesar, Crassus, and Pompey formed a political alliance that dominated Roman politics for several years. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire. Gaius Julius Caesar (13 July 100 BC – 15 March 44 BC), known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose.
