The Brutii were the founders of the Roman Republic, with Lucius Junius Brutus leading the 507 BC revolution that overthrew the Kingdom of Rome and established the Roman Senate and republic. The Brutii were based in Bruttium and Apulia in southern Italy, with their capital at Tarentum. Brutii warriors were the ones responsible for the conquest of the Greek Cities and Pontus in Asia Minor in the 200s BC, and they had a large support base in the eastern parts of the republic. 44 BCE, when Marcus Junius Brutus the Younger and Gaius Cassius Longinus stabbed Julius Caesar to death and renewed the civil war, the Brutii went to war with the House of Julii. Their doom came at the Battle of Philippi in 42 BC, where their leaders and their soldiers were killed by Gaius Octavius.
