The Pact of Misenum was a treaty to end the naval blockade of the Italian Peninsula during the war between the Second Triumvirate and Sextus Pompey. Signed in 39 BC, the triumvirs allowed Sextus Pompeius to retain his control of Sicily and Sardinia and also granted him control of Corsica and the Peloponnesus. They also promised him a future augurate and consulship for 33 BC. In exchange, Pompeius agreed to end his blockade of Italy, supply Rome with grain and halt his piracy.[1]
The pact later fell apart when one of the triumvirs, Mark Antony, refused to cede control of Achaea. Pompeius then resumed hostilities against the triumvirs before being defeated in 36 BC at the naval Battle of Naulochus by Marcus Vipsanius Agrippa.
