Propaganda played an important role in Octavian (l. 63 BCE - 14 CE) and Mark Antony's (l. 83 – 30 BCE) civil war, and once victorious at the Battle of Actium (31 BCE), Octavian returned home to become the first Roman emperor. The decade preceding their civil war was a decisive one. In 43 BCE, Octavian, Antony, and Lepidus (l. 89/88 – 13/12 BCE) formed the Second Triumvirate to "restore order to the state" and declare war on Julius Caesar's assassins. During these pivotal years, Antony was away in the East, preparing for his invasion of Parthia. Octavian mostly stayed in and near Italy, strengthening his image and solidifying his authority among the Roman Senate and people.
