Spanish decolonization of Western Sahara was the process by which Spain relinquished formal control over the territory known as Spanish Sahara, leading to competing claims by Morocco and Mauritania and the emergence of the Polisario Front as a liberation movement. The withdrawal culminated in the Madrid Accords of 1975 and triggered a protracted conflict, international legal disputes before the International Court of Justice and repeated United Nations mediation efforts including the deployment of MINURSO.
From the 1884 Berlin Conference onward, Spain established a colonial presence in the western Sahara Desert as Spanish Sahara, administering the territory alongside possessions such as Spanish Guinea and Spanish Morocco. Colonial administration centered on settlements like El Aaiún and Dakhla and relied on institutions including the Civil Guard and the Spanish Army while exploiting phosphate deposits at Bouehrmim and fisheries off the Atlantic Ocean. During the interwar period and post-World War II decolonization waves, United Nations General Assembly resolutions on non-self-governing territories increasingly targeted Spanish authority in Spanish Sahara, provoking tensions with Madrid and prompting petitions from Sahrawi leaders to bodies such as the UN Visiting Mission to Spanish Sahara.
Sahrawi nationalism coalesced in the 1960s and early 1970s with organizations including the Harakat Tahrir currents and ultimately the foundation of the Polisario Front in 1973 by figures like El-Ouali Mustapha Sayed and Mahfoud Leybay. The Polisario Front conducted guerrilla operations against Spanish outposts and later against Moroccan and Mauritanian forces, drawing support from states like Algeria and Libya and linking with transnational networks including the Organisation of African Unity. Sahrawi leaders appealed to international law bodies including the International Court of Justice and the United Nations Committee on Decolonization, while cultural projects invoked Sahrawi identity in places such as Smara and La Güera.
Legal debates pivoted on the 1975 advisory proceedings at the International Court of Justice, where claimants including King Hassan II of Morocco and representatives of Mauritania presented historical claims involving precolonial ties to territories such as Sijilmasa and tribal affiliations from Ribat al-Fath. The ICJ delivered an advisory opinion acknowledging some legal ties but affirming the principle of self-determination for the Sahrawi people, a stance reflected in United Nations resolutions and calls for a referendum administered by UN organs like the UN Mission for the Referendum in Western Sahara (later MINURSO). Competing diplomatic maneuvers involved actors such as the European Community, the Arab League, and the Organisation of Islamic Cooperation.
Amid internal turmoil in Spain after the Death of Francisco Franco and the Green March organized by Morocco, Madrid negotiated the Madrid Accords with delegations from Morocco and Mauritania in November 1975, represented by officials including Juan Carlos I's Spanish government envoys. The accords arranged withdrawal of Spanish administrative apparatus from El Aaiún and other cities and a tripartite transitional arrangement that Spain argued would end its obligations under mandates such as those derived from the League of Nations. The Polisario Front rejected the accords, and Sahrawi representatives such as Brahim Ghali maintained claims to self-determination and rejected partition.
Following the Madrid Accords, Morocco advanced into northern sectors including Smara and Boujdour while Mauritania occupied southern regions around Tiris al-Gharbiyya; both deployed units drawn from formations like the Royal Moroccan Armed Forces and the Mauritanian Army. The Polisario Front launched sustained guerrilla campaigns, employing tactics adapted to desert warfare and supported by logistics from Algeria and ideological backing from states such as Libya under Muammar Gaddafi. Battles and incidents unfolded near locales such as Amgala and along routes to Nouadhibou, prompting international concern and interventions including OAU mediation attempts and support from the Soviet Union and non-aligned states.
A 1991 ceasefire brokered with United Nations mediation established MINURSO to monitor the truce and prepare for a referendum on status; key figures included James Baker who proposed settlement plans such as the Baker Plan. Disagreements persisted over voter eligibility lists tied to Spanish colonial records and tribal registers, involving administrative archives in El Aaiún and contentious repatriation and identification claims. Morocco proposed autonomy under its sovereignty while the Polisario Front insisted on independence, producing a stalemate examined in UN Security Council resolutions and periodic diplomatic efforts by envoys from states including France and United States administrations.
The decolonization process produced a protracted humanitarian crisis with large Sahrawi refugee populations in camps near Tindouf administered by Algeria and aid from agencies like United Nations High Commissioner for Refugees and International Committee of the Red Cross. Human rights organizations such as Amnesty International and Human Rights Watch documented allegations of abuses in Sahrawi-administered and Moroccan-administered territories, while resource disputes over fisheries and phosphates at sites like Bouehrmim implicated corporations and states including Spain and France. The political stalemate affected regional bodies such as the African Union and influenced bilateral relations among Spain, Morocco, Algeria, and Mauritania, leaving questions of decolonization, self-determination, and territorial sovereignty unresolved and continuing to feature in diplomacy involving actors like the European Union and the United States.
