Treaty of Péronne (1641)

The Treaty of Péronne was signed on September 14, 1641, in Péronne, France between Honoré II, Prince of Monaco, and Louis XIII, King of France. Based on the terms of the treaty, Prince Honoré permitted Monaco to become a French protectorate in return for guarantees entailing the preservation of his rights as sovereign. Moreover, Honoré wanted to be included in all French treaties and be given grants of land in France as compensation for any privately-owned territories he might lose in Habsburg Spain. Overall, the treaty led to the removal of the Spanish garrison in Monaco by the French and ultimately regulated the relations between France and Monaco for 150 years.
