 With the passage of the "lex Titia" on 27 November 43 BC, the Second Triumvirate was officially formed, composed of Antony, Octavian, and Caesar's loyal cavalry commander Lepidus.It formally deified Caesar as Divus Iulius in 42 BC, and Caesar Octavian henceforth became "Divi filius" ("Son of the divine").Because Caesar's clemency had resulted in his murder, the Second Triumvirate reinstated the practice of proscription, abandoned since Sulla.
