14. Navassa Island (Haiti/France)
Navassa Island, located between Haiti and Jamaica, was claimed by France as part of Saint-Domingue (now Haiti) and later by Haiti. The United States also claimed the island under the Guano Islands Act in 1857. Mining operations took place between 1865 and 1898. The dispute with Haiti continues, though the U.S. continues to administer it as a National Wildlife Refuge (fws.gov).
