Tarquinus Superbus, also known as Tarquin the Proud, was the last king of Rome, ruling from 535 to 509 BCE. He is often remembered for his tyrannical reign and the oppressive rule that led to widespread discontent among the Roman people. His rule marked the end of the Roman Kingdom and the beginning of the Roman Republic. His reign ended when he was overthrown following the tragic incident involving Lucretia, a noblewoman who was assaulted by his son, Sextus Tarquinius. This event sparked a revolt led by Lucius Junius Brutus, resulting in the expulsion of Tarquinus Superbus and the establishment of a republican government in Rome.
