Tensions came to a head when the king's son, Sextus Tarquinius, raped Lucretia, wife and daughter to powerful Roman nobles. Lucretia told her relatives about the attack, and committed suicide to avoid the dishonour of the episode. Four men, led by Lucius Junius Brutus, and including Lucius Tarquinius Collatinus, Publius Valerius Poplicola, and Spurius Lucretius Tricipitinus incited a revolution that deposed and expelled Tarquinius and his family from Rome in 509 BC.
