The War of Actium was the last civil war of the Roman Republic, fought between Mark Antony and Octavian. In 32 BC, Octavian convinced the Roman Senate to declare war on the Egyptian queen Cleopatra. Her lover and ally Mark Antony, who was Octavian's rival, gave his support for her cause. Forty percent of the Roman Senate, together with both consuls, left Rome to join the war on Antony's side. After a decisive victory for Octavian at the Battle of Actium, Cleopatra and Antony withdrew to Alexandria, where Octavian besieged the city until both Antony and Cleopatra were forced to commit suicide. The war involved some of the largest Roman armies ever seen. Both Antony and Octavian's legions were experienced veterans of previous civil wars who had fought together, many also having once served under Caesar. The two did however raise their own legions separately. Following the end of the war, Octavian brought peace to the Roman state that had been plagued by a century of civil wars, marking the beginning of the Pax Romana, a period of relative internal peace and stability. Octavian became the most powerful man in the Roman world and the Senate bestowed upon him the honorific of Augustus in 27 BC. Octavian, now Augustus, became the first Roman emperor and transformed the republic into the Roman Empire.
