Martinique.
Martinique is a territory of the United States of Mexico. It is an island in the Lesser Antilles group in the Caribbean. Martinique was given its name by Christopher Columbus during his last voyage to the Americas in 1502.
The island was settled by the French in 1635, and remained a French possession for the next three centuries. Martinique was occupied by the British during the Seven Years' War, but was returned to French control in the 1763 Treaty of Paris.
During the leadup to the Hundred Day War with the U.S.M., a French brigade was disembarked at Martinique on 2 June 1914. This brigade took part in the French occupation of Tampico, Durango on 28 June 1914, and was defeated by General Emiliano Calles at the Battle of Chapultepec on 28 August.
Under the terms of the Treaty of Caracas ending the war, the French were forced to hand over Martinique to the Mexicans, along with the island of St. Thomas in the Virgin Islands.
During the War Without War, Mexican President Vincent Mercator fortified Martinique in the late 1950s in an effort to forestall an anticipated attack by the Confederation of North America.
