Mark Antony was amassing political support, but Octavian still had opportunity to rival him as the leading member of the faction supporting Caesar.
Mark Antony had lost the support of many Romans and supporters of Caesar when he initially opposed the motion to elevate Caesar to divine status.
He was born at Ox Head, a small property on the Palatine Hill, very close to the Roman Forum.
He was given the name Gaius Octavius Thurinus, his cognomen possibly commemorating his father's victory at Thurii over a rebellious band of slaves.
The Triumvirate was eventually torn apart by the competing ambitions of its members.
Lepidus was driven into exile and stripped of his position, and Antony committed suicide following his defeat at the Battle of Actium by Octavian in 31 BC.
Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia; expanding possessions in Africa; expanding into Germania; and completing the conquest of Hispania.
