Marcus Antonius (in Latin: M·ANTONIVS·M·F·M·N) (c. January 14, 83 BC–August 1, 30 BC), known in English as Marc Antony, was a Roman politician and General. He was an important supporter and the best friend of Gaius Julius Caesar as a military commander and administrator, being Caesar's second cousin, once removed, by his mother Julia Antonia. After Caesar's assassination, Antony formed an official political alliance with Octavian (Augustus) and Marcus Aemilius Lepidus, known to historians today as the Second Triumvirate.
The triumvirate broke up in 33 BC. Disagreement between Octavian and Antony erupted into civil war, the Final War of the Roman Republic, in 31 BC. Antony was defeated by Octavian at the naval Battle of Actium, and in a brief land battle at Alexandria. He committed suicide, and his lover, the Queen Cleopatra of Egypt, killed herself shortly thereafter.
