What significant event occurred in 42 BC involving Cassius and Brutus?

In 42 BC, Cassius and Brutus, key figures in the assassination of Julius Caesar, faced defeat at the Battle of Philippi against the forces of the Second Triumvirate, which included Octavian and Mark Antony. Following their defeat, both Cassius and Brutus chose to commit suicide rather than face capture or further disgrace. This event marked the end of the Liberators' civil war and highlighted the dramatic shifts in power within the Roman Republic after Caesar's assassination. Their suicides are often seen as a testament to their beliefs in honor and the Roman ideals of bravery in defeat, solidifying their roles as tragic figures in history.
