According to Roman tradition, Lucretia (/luːˈkriːʃə/ loo-KREE-shə, Classical Latin: [ɫʊˈkreːtia]; died c.  510 BC), anglicized as Lucrece, was a noblewoman in ancient Rome. Sextus Tarquinius (Tarquin) raped her and her subsequent suicide precipitated a rebellion that overthrew the Roman monarchy and led to the transition of Roman government from a kingdom to a republic. After Tarquin raped Lucretia, flames of dissatisfaction were kindled over the tyrannical methods of Tarquin's father, Lucius Tarquinius Superbus, the last king of Rome. As a result, the prominent families instituted a republic, drove the extensive royal family of Tarquin from Rome, and successfully defended the republic against attempted Etruscan and Latin intervention.There are no contemporary sources of Lucretia and Tarquin’s rape of her. Information regarding Lucretia, how and when Tarquin raped her, her suicide, and the consequence of this being the start of the Roman Republic, come from the accounts of Roman historian Livy and Greco-Roman historian Dionysius of Halicarnassus approximately 500 years later. Secondary sources on the establishment of the republic reiterate the basic events of Lucretia's story, though accounts vary slightly between historians. The evidence points to the historical existence of a woman named Lucretia and an event that played a critical part in the downfall of the monarchy. However, specific details are debatable and vary depending on the writer. According to modern sources, Lucretia's narrative is considered a part of Roman mythohistory. Much like the rape of the Sabine women, Lucretia's story provides an explanation for historical change in Rome through a recounting of sexual assault against women by men. Source: Wikipedia (en)
