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). The island has been divided since the signing of the Treaty of Concordia in 1648, which today remains as one of the oldest treaties still in effect.

The Treaty of Concordia allows freedom of movement between both parts of the island, which has promoted a common sentiment among the island's inhabitants, although this is also the reason why some see a formal unification as unnecessary. Other arguments against unification of the island are that neither France nor the Netherlands would allow it and that both sides would require full independence to achieve it.
