The Tangier International Zone was a 373 km2 (144 sq mi) international zone centered on the city of Tangier, Morocco, then under French and Spanish protectorate, under the joint administration of France, Spain, and the United Kingdom (later Portugal, Italy, Belgium, the Netherlands, Sweden, and the United States), that existed from 1924 until its reintegration into independent Morocco in 1956.
The zone was governed in accordance with the Tangier Protocol, although the Sultan of Morocco retained nominal sovereignty over the zone and jurisdiction over the native population.
