The Regifugium, on February 24, is one of the most enigmatic observances of the Roman calendar. Its name means “flight of the king,” and for the ancients it recalled the expulsion of Rome’s last king. Modern scholars are less sure.
- Date: February 24
- Protagonist of the rite: the rex sacrorum, the “king of sacrifices”
- Place: the Comitium, in the Roman Forum
- Tradition: expulsion of Tarquin the Proud, 509 BC according to the traditional chronology

The rite in the Comitium
According to the ancient sources, the rex sacrorum, the priest who inherited the religious duties of the kings, performed a sacrifice in the Comitium and then ran off, almost as if fleeing. Plutarch mentions it in the Roman Questions as a gesture the Romans linked to the end of the monarchy.
The legend of Tarquin
Ovid, in the Fasti, ties the date to the expulsion of Tarquin the Proud after the outrage against Lucretia, the story that opens the Republic in the traditional chronology. It should be read as a foundation myth: modern historians debate how much of it is historical and how much is later reconstruction.

What scholars think
A more cautious modern reading sees the Regifugium as a rite of purification and of the turn of the year, close to the Lupercalia and the Terminalia: the sacred king symbolically drives away disorder before the new cycle. There is no consensus, and anyone who presents it as established fact is oversimplifying.
