Marcus Antonius - Triumvir of Res publica Romana from 27th of November 43 BC to 31st of December 33 BC
Marcus Antonius was a politician and general who played a critical role in transforming the Roman Republic from an oligarchy into an Empire.

As a supporter of Julius Caesar, he served as one of his generals during the conquest of Gaul and the Civil War. After Caesar's death in 44 BC, Antonius joined forces with Lepidus and Octavian to form the 2nd Triumvirate.

Relations among the triumvirs were strained. Lepidus was expelled in 36 BC, and in 31 BC a civil war erupted, as the Roman Senate declared war on Cleopatra and proclaimed Antonius a traitor. After the Battle of Actium, Antonius and Cleopatra fled to Egypt, where they committed suicide.
