 As all three had been partisans of Caesar, their main targets were opponents of the Caesarian faction.The most notable victims were Marcus Tullius Cicero, who had opposed Caesar and excoriated Antony in his "Philippicae," and Marcus Favonius, a follower of Cato and an opponent of both triumvirates.The proscription of Caesar's legate Quintus Tullius Cicero (Marcus Tullius Cicero's younger brother) seems to have been motivated by the perceived need to destroy Cicero's family.
