Sextus Pompeius Magnus Pius, in English Sextus Pompey (67 BC – 35 BC), was a Roman general from the late Republic (1st century BC). He was the last focus of opposition to the Second Triumvirate. His father was Gnaeus Pompeius Magnus (Pompey the Great). Shakespeare had him as a major character in his play Antony and Cleopatra (1606–07).
Sextus Pompeius was the youngest son of Pompey the Great (Gnaeus Pompeius Magnus) by his third wife, Mucia Tertia. His older brother was Gnaeus Pompeius. Both boys grew up in the shadow of their father, one of Rome's best generals and an originally non-conservative politician who drifted to the more traditional faction when Julius Caesar became a threat.
When Caesar crossed the Rubicon in 49 BC, thus starting a civil war, Sextus' older brother Gnaeus followed their father in his escape to the East, as did most of the conservative senators. Sextus stayed in Rome in the care of his stepmother, Cornelia Metella. Pompey's army lost the Battle of Pharsalus in 48 BC and Pompey himself had to run for his life. Cornelia and Sextus met him in the island of Lesbos and together they fled to Egypt. On the arrival, Sextus watched his father being killed by treachery on September 29 of the same year. After the murder, Cornelia returned to Rome, but in the following years Sextus joined the resistance against Caesar in the African provinces. Together with Metellus Scipio, Cato the Younger, his brother Gnaeus and other senators, they prepared to oppose Caesar and his army to the end.
