Lucius Junius Brutus was the founder of the Roman Republic, and one of the first consuls in 509 BC. He was the nephew of the King of Rome, Lucius Tarquinius Superbus. Brutus had been summoned by the noblewoman Lucretia after she had been raped by the King's son. She believed that the rape defiled her, and she committed suicide by stabbing herself with a knife. It is said that Brutus held the knife, shouting for the overthrow of the Monarchy.
