United Nations Mission for the Referendum in Western Sahara in the context of "Sahrawi people"

Western Sahara is a non-self-governing territory in North-western Africa undergoing decolonization. It has a surface area of 272,000 square kilometres (105,000 sq mi). Western Sahara is the last African colonial state yet to achieve independence and has been dubbed "Africa's last colony". With an estimated population of around 600,000 inhabitants, it is the most sparsely populated territory in Africa and the second most sparsely populated territory in the world, consisting mainly of desert flatlands.

Spain previously colonized the territory as the Spanish Sahara until 1976, when it attempted to transfer its administration to Morocco and Mauritania while ignoring an International Court of Justice's verdict that those countries had no sovereignty over Western Sahara. A war erupted and the Polisario Front—a national liberation movement recognized by the United Nations as the legitimate representative of the people of Western Sahara—proclaimed the Sahrawi Arab Democratic Republic (SADR) with a government-in-exile in Tindouf, Algeria. Mauritania withdrew its claims in 1979, and Morocco secured de facto control of most of the territory, including all major cities and most natural resources. A UN-sponsored ceasefire agreement was reached in 1991, though a planned referendum monitored by the UN's MINURSO mission has since stalled.

The Popular Front for the Liberation of Saguia el-Hamra and Río de Oro, better known by its acronym Polisario Front, is a Sahrawi nationalist liberation movement seeking to end the occupation of Western Sahara through the means of self-determination and armed resistance.

Tracing its origin to a Sahrawi nationalist organization known as the Movement for the Liberation of Saguia el Hamra and Wadi el Dhahab, the Polisario Front was formally constituted in 1973 with the intention of launching an armed struggle against the Spanish occupation which lasted until 1975, when the Spanish decided to allow Mauritania and Morocco to partition and occupy the territory. The Polisario Front proclaimed the Sahrawi Arab Democratic Republic (SADR) on 27 February 1976, and waged a war to drive out the two armies. It forced Mauritania to relinquish its claim over Western Sahara in 1979 and continued its military campaign against Morocco until the 1991 ceasefire, pending the holding of a UN-backed referendum which has been consistently postponed ever since. In 2020 the Polisario Front declared the ceasefire over and resumed the armed conflict.

Laayoune or El Aaiún (Arabic: العيون, al-ʕuyūn [alʕujuːn], Hassaniyya: [ˈləʕjuːn] , lit. 'The Springs') is the largest city of the disputed territory of Western Sahara, with a population of 271,344 in 2023. The city is the de jure capital of the Sahrawi Arab Democratic Republic, though it is under de facto Moroccan administration as occupied territory. The modern city is thought to have been founded by the Spanish captain Antonio de Oro in 1938. From 1958, it became the administrative capital of the Spanish Sahara, administered by the Governor General of Spanish West Africa.

In 2023, Laayoune is the capital of the Laâyoune-Sakia El Hamra region administered by Morocco, it is still under the supervision of MINURSO, a UN mission.

Clashes between military forces belonging to the Kingdom of Morocco and the self-proclaimed Sahrawi Arab Democratic Republic (SADR), represented at the United Nations by the Polisario Front, broke out in the disputed region of Western Sahara in November 2020. It was the latest escalation of an unresolved conflict over the region, which is largely occupied by Morocco, but 20–25% is administered by the SADR. The violence ended a ceasefire between the opposing sides that had held for 29 years in anticipation of a referendum on self-determination that would have settled the dispute. Despite the establishment of the United Nations Mission for the Referendum in Western Sahara in 1991, the referendum was never held.

Tensions between Morocco and the Polisario Front deepened in mid-October 2020 when Sahrawi peaceful protesters blocked a controversial road connecting Moroccan-occupied Western Sahara to sub-Saharan Africa. The protesters camped on the road near the small village of Guerguerat, which passes through a 5-kilometre-wide buffer strip monitored by the UN. Despite the controversy, the route had grown in economic importance, such that the protest stranded about 200 Moroccan truck drivers on the Mauritanian side of the border. According to the MINURSO, both Morocco and Polisario deployed forces near the area in late October, with Mauritanian forces reinforcing their positions along its border with Western Sahara.

United Nations Security Council resolution 690, was adopted unanimously on 29 April 1991. After recalling resolutions 621 (1988) and 658 (1990) and noting a report by the Secretary-General on the situation in Western Sahara, the Council approved the report and decided to establish the United Nations Mission for the Referendum in Western Sahara (MINURSO) in accordance with the Secretary-General's recommendations. The Mission was to implement the Settlement Plan for a referendum of self-determination for the people of Western Sahara.

The Council called upon Morocco and the Polisario Front to co-operate with the Secretary-General and the Mission, expressing its full support to him and the Organisation of African Unity for their efforts. It also decided that the transitional period will begin no later than sixteen weeks after the General Assembly approves the budget of MINURSO. In May 1991, the General Assembly approved the budget.

The Settlement Plan (Arabic: خطة التسوية, romanized: Khiṭṭah al-Taswiyah; Spanish: Plan de Arreglo) was an agreement between the ethnically Sahrawi Polisario Front and Morocco on the organization of a referendum, which would constitute an expression of self-determination for the people of Western Sahara, leading either to full independence, or integration with the Kingdom of Morocco. It resulted in a cease-fire which remained effective until 2020, and the establishment of the MINURSO peace force to oversee it and to organize the referendum. The referendum never occurred.

The Moroccan Western Sahara Wall or the Berm, also called the Moroccan sand wall (Arabic: الجدار الرملي, romanized: al-jidār ar-ramliyya, lit. 'sand wall'), is an approximately 2,700 km-long (1,700 mi) berm running south to north through Western Sahara and the southwestern portion of Morocco. It separates the Moroccan-occupied areas (the Southern Provinces) on the west from the Polisario-controlled areas (Free Zone, nominally Sahrawi Arab Democratic Republic) on the east. The main function of the barriers is to prevent a Sahrawi state, keeping independence-seekers away from the region's natural resources, located in the Moroccan-occupied part of the territory.

According to maps from the United Nations Mission for the Referendum in Western Sahara (MINURSO) or the United Nations High Commissioner for Refugees (UNHCR), in many places the wall extends several kilometers into internationally recognized Mauritanian territory.
