Regifugium
The 'Flight of the King', which Romans linked to the expulsion of Tarquin.
Background
The Regifugium, "Flight of the King", fell on 24 February, near the end of the old Roman year. Romans of Ovid's day connected it with the expulsion of Tarquin the Proud, the last king, in what they dated to 509 BC tradition.
Ovid devotes a long passage to the story: the rape of Lucretia by the king's son Sextus Tarquinius, her suicide after telling her family, and Lucius Junius Brutus swearing over her body to drive out the royal family per Ovid and Livy; legend. Modern scholars doubt the connection with the festival; the Regifugium may have been a rite in which the rex sacrorum performed a sacrifice in the Comitium and then hurried away disputed; per Plutarch.
The Lucretia story placed a woman's violation and death at the founding of the Republic, and Roman writers used it to teach what they saw as female virtue and the evils of tyranny. Hatred of the name "king" remained a powerful force in Roman politics for centuries, which is why Caesar's enemies could use it so effectively against him.
