Lucretia or Lucrece (Latin: Lucretia; died ) was a legendary Roman matron whose fate played a vital role in the transition from a Roman Kingdom into a Roman Republic. While there were no contemporary sources, accounts from Roman historian Livy (Livius) and Greek-Roman historian Dionysius of Halicarnassus from the time of Emperor Caesar Augustus (around the start of the Common Era) agreed that there was such a woman and that her suicide after being raped by an Etruscan king's son was the immediate cause of the anti-monarchist rebellion that overthrew the monarchy.
