The history of the Grimaldi dynasty dates back to January 8, 1297. That's when Francois Grimaldi, disguised as a Franciscan monk, seized the fortress towering over the Monaco rock with his troops, in the port of Hercule.
Marquis of Baux, Count of Polignac, Sir of Matignon, Duke of Mayenne, Baron of Massy, Count of Torigni... These and other titles belong to just one person - the reigning prince of Monaco.
