Lucretia

Lucretia (died c.508 B.C.) is a semi-legendary figure in the history of the Roman Republic. According to the story, told mainly by two turn-of-the-millenium historians, the Roman Livy and the Greek historian Dionysius of Halicarnassus (who lived in Rome at the time of the Roman Emperor Caesar Augustus), her rape by the king's son and consequent suicide were the immediate cause of the revolution that overthrew the monarchy and established the Roman Republic.
