The country is subdivided into 15 provinces and one special municipality (Isla de la Juventud). These were formerly part of six larger historical provinces: Pinar del Río, Habana, Matanzas, Las Villas, Camagüey and Oriente. The present subdivisions closely resemble those of the Spanish military provinces during the Cuban Wars of Independence, when the most troublesome areas were subdivided. The provinces are divided into municipalities.
