The Servian constitution creates the comitia centuriata (assembly of centuries), tying military obligation to political rights. He also expands Rome's boundaries with the Servian Wall and creates the four urban tribes. His reforms lay the constitutional foundations that will persist through the Republic.
534 BC – 509 BCTarquinius Superbus — the last kingLucius Tarquinius Superbus (Tarquin the Proud), seventh and final king of Rome, rules by terror. He murders his father-in-law Servius Tullius, abolishes the Senate's power, and rules as a tyrant in the Greek mould. His son Sextus rapes the noblewoman Lucretia, who kills herself after naming her assailants. Her kinsman Lucius Junius Brutus leads the aristocratic revolt that expels the Tarquins in 509 BC, ending the monarchy forever.
