(M. Junius) Brutus was a Republican; and he was also the nephew of (M. Porcius) Cato, who was one of Caesar's opponents during the end of the Republic. (Cato opposed Caesar's run for the position of consul, but his uncompromising attitude when it came to the integrity of the senate backfired, alienating people who could have been allies and turning them into allies of Caesar, thus allowing Caesar to win the election). Brutus was also the first person to take advantage of Caesar's clemency after the Battle of Pharsalus in 48 BC. After being pardoned (for being a Republican), he was appointed as a praetor in 44 BC along with Cassius (a fellow Republican). In the end, Brutus was one of the sixty men involved in Caesar's assassination on the Ides of March (March 15) in 44 BC.
