Second Triumvirate

The Second Triumvirate is the name historians give to the official political alliance of Octavian (later known as Augustus), Marcus Aemilius Lepidus, and Mark Antony, formed on 26 November 43 BC with the enactment of the Lex Titia, the adoption of which marked the end of the Roman Republic. The Triumvirate existed for two five-year terms, covering the period 43 BC – 33 BC.

Unlike the earlier First Triumvirate, the Second Triumvirate was an official, legally established institution, whose overwhelming power in the Roman state was given full legal sanction and whose imperium maius outranked that of all other magistrates, including the consuls.
