Sextus Pompey

Sextus Pompeius Magnus Pius (c. 67 – 35 BC), also known in English as Sextus Pompey, was a Roman military leader who, throughout his life, upheld the cause of his father, Pompey the Great, against Julius Caesar and his supporters during the last civil wars of the Roman Republic.

Sextus Pompey formed the last organized opposition to the Second Triumvirate, in defiance of which he succeeded in establishing an independent state in Sicily for several years.
