The overthrow of the Roman monarchy was an event in ancient Rome that took place between the 6th and 5th centuries BC where a political revolution replaced the then-existing Roman monarchy under Lucius Tarquinius Superbus with a republic. The details of the event were largely forgotten by the Romans a few centuries later; later Roman historians presented a narrative of the events, traditionally dated to c. 509 BC, but it is largely believed to be fictitious by modern scholars.
The traditional account portrays a dynastic struggle in which the king's second son, Sextus Tarquinius, rapes a noblewoman, Lucretia.[1] Upon revealing the assault to some Roman noblemen, she kills herself. The Roman noblemen, led by Lucius Junius Brutus, obtain the support of the Roman aristocracy and the people to expel the king and his family and create a republic. The Roman army, supporting Brutus, forces the king into exile. Despite a number of attempts by Lucius Tarquinius Superbus to reinstate the monarchy, the Roman people are successful in establishing a republic and thereafter elected two consuls annually to rule the city.
Many modern scholars dismiss this narrative as fictitious. There does not exist, however, any concrete evidence for or against it. Various scholars have dismissed aspects of the traditional story, from the historicity of almost all of its major characters to the overthrow's entire existence.
