Treaty of Péronne (1641)
The Treaty of Péronne was signed on September 14, 1641, in Péronne, France between Honoré II, Prince of Monaco and King Louis XIII 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 may lose in 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.

He had long been scheming with Richelieu to exchange the Spanish for a French protectorate, and in 1641 the treaty of Péronne regulated for the next century and a half the relations of Monaco and France. A French garrison was to occupy the fortress, but the Prince was to preserve his sovereign rights, to be included in all French treaties, and be compensated for the property which he will lose in Spain by grants of lands in France. The fortress was captured by means of a surprise, the French garrison established, and the Prince created Duc de Valentinois - a title which still runs in the family - and received with the greatest honours at the French Court.
