While the members of the Senate's aristocratic faction, or optimates, seethed, the minions of the so-called First Triumvirate maintained their stranglehold on Roman politics.
Augustus worked to restore the Senate’s prestige, improved food security for the lower classes, and relinquished control of the army when he resigned his consul post.
By around 50 BC, these leaders had become so powerful that they no longer listened to the commands of consuls and ignored the recommendations of the Senate.
On the other side were the Senatorial optimates, allied with the assassins of Caesar or the so-called republicans, led by the silver-tongued old statesman Cicero.
