The Sicilian revolt against the Second Triumvirate of the Roman Republic ended when the fleet of Sextus Pompey, the rebel leader, was defeated at the Battle of Naulochus.

The Bellum Siculum was an Ancient Roman civil war waged between 42 BC and 36 BC by the forces of the Second Triumvirate and Sextus Pompey, the last surviving son of Pompey the Great and the last leader of the Optimate faction. The war consisted of mostly a number of naval engagements throughout the Mediterranean Sea and a land campaign primarily in Sicily that eventually ended in a victory for the Triumvirate and Sextus Pompey's death. The conflict is notable as the last stand of any organised opposition to the Triumvirate.

The Second Triumvirate was an extraordinary commission and magistracy created at the end of the Roman republic for Mark Antony, Lepidus, and Octavian to give them practically absolute power. It was formally constituted by law on 27 November 43 BC with a term of five years; it was renewed in 37 BC for another five years before expiring in 32 BC. Constituted by the lex Titia, the triumvirs were given broad powers to make or repeal legislation, issue judicial punishments without due process or right of appeal, and appoint all other magistrates. The triumvirs also split the Roman world into three sets of provinces.

The Roman Republic was the era of classical Roman civilisation beginning with the overthrow of the Roman Kingdom and ending in 27 BC with the establishment of the Roman Empire following the War of Actium. During this period, Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world.

Sextus Pompeius Magnus Pius, 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.
