Tangier International Zone

From 1925 to 1956 (except Spain's 1940-45 occupation) Tangier and its district were run under a treaty statute by France, Britain and Spain, later joined by Italy and others: an international administrator, a nominated assembly, a Mixed Court and a free-trade regime.

The Convention of 18 December 1923, revised in 1928, left the Zone under the Sultan of Morocco's nominal sovereignty, represented by a Mendoub, and made it permanently neutral and demilitarised. An administrator carried out decisions of an International Legislative Assembly of foreign members nominated by consulates plus Muslim and Jewish Moroccans named by the Mendoub; a Committee of Control of consuls could veto its enactments. A Mixed Court replaced consular jurisdiction. Customs duties applied only to goods consumed in the Zone, and a free money market and light taxation drew banking, gold trading and smuggling. The regime ended after Moroccan independence.

Outcomes & controversies

Tangier became a free port and financial haven, with prosperity after 1945 resting on banking, gold trading and contraband. A 1957 observer judged the regime unjust: run by and for about 60,000 foreigners, with little regard for about 120,000 Moroccans.

Post-mortem

The regime rested on consent among the powers and on Morocco's protectorate status. After Moroccan independence, a conference of the powers and Morocco met in October 1956, recognised the abolition of the international regime and restored full Moroccan sovereignty over Tangier.
