Brutus held his uncle in high regard[4] and his political career started when he became an assistant to Cato, during his governorship of Cyprus.[5] During this time, he enriched himself by lending money at high rates of interest. He returned to Rome a rich man, where he married Claudia Pulchra.[6] From his first appearance in the Senate, Brutus aligned with the Optimates (the conservative faction) against the First Triumvirate of Marcus Licinius Crassus, Gnaeus Pompeius Magnus and Gaius Julius Caesar.
[edit] Senate career
When civil war broke out in 49 BC between Pompey and Caesar, Brutus followed his old enemy and present leader of the Optimates, Pompey. When the Battle of Pharsalus began, Caesar ordered his officers to take him prisoner if he gave himself up voluntarily, and if he persisted in fighting against capture, to let him alone and do him no violence.[7] After the disaster of the battle of Pharsalus, Brutus wrote to Caesar with apologies and Caesar immediately forgave him. In his letter Brutus declared he was a strong supporter of democracy and continually pushed it throughout the letter.[citation needed] Caesar accepted him into his inner circle and made him governor of Gaul when he left for Africa in pursuit of Cato and Metellus Scipio. In 45 BC, Caesar nominated Brutus to serve as urban praetor for the following year.
