Pompey fled to Egypt, but he was betrayed and killed when he came ashore.
Marius and his ally Lucius Cornelius Cinna were in control of the city when Caesar was nominated as the new Flamen Dialis high priest of Jupiter and he was married to Cinna's daughter Cornelia.
Pompey filled the city with soldiers, a move which intimidated the triumvirate's opponents. Not long after, Caesar secured the governorship of Gaul modern-day France and Belgium. These attempts proved ineffective in obstructing Caesar's legislation.
He made allies with powerful men such as the general Pompey the Great and the wealthy Crassus. He knew he needed a great military victory to win lasting glory beyond politics, so he set out to conquer the long-defiant Gauls—Celts who lived in modern-day France.
Caesar continually strove for more power to govern, with as little dependence as possible on honorary titles or the Senate. It is improbable that Caesar deliberately sought monarchical power until after he had crossed the Rubicon in 49 bce, though sufficient power to impose his will, as he was determined to do, proved to mean monarchical power.
