One of this man's few tactical mistakes was putting the queen Arsinoe ("Ar-SIN-o-way") IV on display, moving spectators to sympathy with those whom he had conquered. Once he became ruler, he gave himself the title of "Father of the Fatherland" and increased the Senate to nearly 900 members. Although this ruler had been ordered to divorce his wife after the triumph of Sulla, this man remained with her until her death. This ruler defeated Pompey at the Battle of Pharsalus, whom he was part of the First Triumvirate with, along with Crassus. For 10 points, name this ruler of the Roman Empire who was murdered on the Ides of March.
