Monaco National Day
Thursday, November 19, 2026
In 1861, Sovereign. Power Recognized. Monaco's sovereignty was officially recognized by the Treaty of Paris, laying the foundation for a National Day observance
History
Monaco National Day on November 19 commemorates the signing of the Treaty of Paris in 1861, which recognized Monaco's full sovereignty as an independent principality. The Grimaldi family has ruled Monaco since 1297, when Francesco Grimaldi seized control of the rock fortress. For centuries, Monaco's sovereignty was recognized by various European powers, but the 1861 treaty with France established formal independence and defined Monaco's borders. Prior to this, Monaco was closely associated with France through various arrangements. November 19 marks the day when Monaco's independence was internationally recognized, allowing the principality to develop as a sovereign state. The celebration reflects Monaco's unique status as one of the world's smallest and oldest sovereign nations, ruled continuously by the Grimaldi family for over 700 years.
