Unification of Saint Martin
The unification of Saint Martin (Dutch: Eenwording van Sint Maarten; French: Unification de Saint-Martin) is the proposed unification of the small island of Saint Martin, located in the Caribbean Sea. Currently, it is divided into Sint Maarten (the southern portion of the island, one of the constituent countries within the Kingdom of the Netherlands) and the Collectivity of Saint Martin (the northern portion of the island, an integral part of France).
