 When Julius Caesar was assassinated on March 15, 44 BC, Sextus' name was placed on a proscription list formed by Marcus Lepidus, Marcus Antonius, and Octavian, the members of the Second Triumvirate.The list was designed not only to fill Rome's treasury, but to help in the Second Triumvirate's war on the Cassii and Bruti families, and listed all of Caesar's other enemies and their relatives.Upon finding his name upon this list, Sextus decided to pick up where his father had left off.
