Although some minor rebellions took place afterward, the Gallic Wars concluded with the battle of Alesia in 52 BCE, and a Roman victory. The result of the Wars was the vast expansion of the Roman Republic with the annexation of Gaul and a tremendous boost in Julius Caesar’s political career. Following the Gallic Wars, a Civil War broke out in Rome from 50 to 48 BCE. Coming off of his victory against the Gauls, Caesar was ordered to disband his army and return to Rome in 50, but he refused. Pompey, the consul who ordered Caesar's return, subsequently accused him of treason. Caesar then rallied his remaining troops and formed a single legion, with which he would start a civil war against Pompey, who fled south, knowing that although he may outnumber Caesar's thirteenth, he could never hope to defeat his more seasoned troops. Caesar finally caught up to Pompey at Pharsalus, and a battle ensued, ending with the defeat of Pompey and the appointment of Julius Caesar as dictator of Rome.
