François Grimaldi, known as "Malizia" (the Cunning), captures the fortress of Monaco by gaining entry by deception disguised as a Franciscan monk and establishing the Grimaldi family's rule.
This event marked the beginning of the Grimaldi dynasty's claim to Monaco and is commemorated on the country's coat of arms, which features two monks brandishing swords. François Grimaldi only held Monaco for four years when he was expelled by the Genoese. It was his cousin Rainier I, and later Rainier's descendants, who solidified the Grimaldi family's long-term rule over Monaco, which continues to this day.
