Marcus Antonius, commonly known in English as Mark Antony (Latin: ) (April 20, 83 BC – August 1, 30 BC), was a Roman politician and general. As a military commander and administrator, he was an important supporter and loyal friend of his mother's cousin Julius Caesar. After Caesar's assassination, Antony formed an official political alliance with Octavian (the future Augustus) and 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 and his lover Cleopatra committed suicide shortly thereafter. His career and defeat are significant in Rome's transformation from Republic to Empire.
