On 1 January 42 BC, nearly two years after the assassination of Julius Caesar on 15 March 44 BC, but before the final victory of the Second Triumvirate over the conspirators who had taken his life, the Roman Senate recognised Caesar as a divinity. He was therefore referred to as "Divus Iulius" ("the divine Julius"), and his adopted son Octavian styled himself "Divi filius" ("son of the deified one, son of the god"). The fuller form, "divi Iuli filius" ("son of the divine Julians"), was also used.
