Antony was a supporter of Julius Caesar , and served as one of his generals during the conquest of Gaul and the Civil War . Antony was appointed administrator of Italy while Caesar eliminated political opponents in Greece , North Africa , and Spain . After Caesar 's death in 44 BC , Antony joined forces with Marcus Aemilius Lepidus , another of Caesar 's generals , and Octavian , Caesar 's great-nephew and adopted son , forming a three-man dictatorship known to historians as the Second Triumvirate . The Triumvirs defeated Caesar 's murderers , the Liberatores , at the Battle of Philippi in 42 BC , and divided the government of the Republic between themselves . Antony was assigned Rome 's eastern provinces , including the client kingdom of Egypt , then ruled by Cleopatra VII Philopator , and was given the command in Rome 's war against Parthia
