Marble sculpture of Emperor Augustus, born Gaius Octavius on 23 September 63 BC in Rome. In 43 BC his great-uncle, Julius Caesar, was assassinated and in his will, Octavius, known as Octavian, was named as his heir. He fought to avenge Caesar and in 31 BC defeated Antony and Cleopatra at the Battle of Actium. He was now undisputed ruler of Rome. Instead of following Caesar's example and making himself dictator, Octavian in 27 BC founded the principate, a system of monarchy headed by an emperor holding power for life. His powers were hidden behind constitutional forms, and he took the name Augustus meaning 'lofty' or 'serene'. Nevertheless, he retained ultimate control of all aspects of the Roman state, with the army under his direct command.
