Western Sahara War in the context of "Moroccan-occupied Western Sahara"

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.

The Sahrawi refugee camps (Arabic: مخيمات اللاجئين الصحراويين; Spanish: Campamentos de refugiados saharauis), also known as the Tindouf camps, are a collection of refugee camps set up in the Tindouf Province, Algeria, in 1975–76 for Sahrawi refugees fleeing from Moroccan forces, who advanced through Western Sahara during the Western Sahara War. With most of the original refugees still living in the camps, the situation is among the most protracted in the world.

The limited opportunities for self-reliance in the harsh desert environment have forced the refugees to rely on international humanitarian assistance for their survival. However, the Tindouf camps differ from the majority of refugee camps in the level of self-organization. Most affairs and camp life organization are run by the refugees themselves, with little outside interference.

The Western Sahara conflict is an ongoing conflict between the Sahrawi Arab Democratic Republic (SADR) and the Kingdom of Morocco. The conflict originated from an insurgency by the Polisario Front against Spanish colonial forces from 1973 to 1975 and the subsequent Western Sahara War against Morocco between 1975 and 1991. Today the conflict is dominated by unarmed civil campaigns of the Polisario Front and their self-proclaimed SADR state to gain fully recognized independence for Western Sahara.

The conflict escalated after the withdrawal of Spain from the Spanish Sahara in accordance with the Madrid Accords. Beginning in 1975, the Polisario Front, backed and supported by Algeria, waged a 16-year-long war for independence against Mauritania and Morocco. In February 1976, the Polisario Front declared the establishment of the Sahrawi Arab Democratic Republic, which was not admitted into the United Nations, but won limited recognition by a number of other states. Following the annexation of Western Sahara by Morocco and Mauritania in 1976, and the Polisario Front's declaration of independence, the UN addressed the conflict via a resolution reaffirming the right to self-determination of the Sahrawi people. In 1977, France intervened as the conflict reached its peak intensity. In 1979, Mauritania withdrew from the conflict and territories, leading to a stalemate through most of the 1980s. The Polisario Front and the Moroccan government reached a cease-fire agreement after several more engagements between 1989 and 1991. At the time, most of the Western Sahara remained under Moroccan control, while the Polisario controlled some 30% of the territory in its capacity as the Sahrawi Arab Democratic Republic. At present, these borders are largely unchanged.

The Green March was a strategic mass demonstration in November 1975, coordinated by the Moroccan government and military, to force Spain to hand over the disputed, autonomous semi-metropolitan province of Spanish Sahara to Morocco. The Spanish government was preparing to abandon the territory as part of the decolonization of Africa, just as it had granted independence to Equatorial Guinea in 1968. The native inhabitants, the Sahrawi people, aspired to form an independent state. The demonstration of 350,000 Moroccans advanced several kilometers into the Western Sahara territory. Morocco later gained control of most of the former Spanish Sahara, which it continues to hold.

The Green March was condemned by the international community, notably in the United Nations Security Council Resolution 380. The march was considered an attempt to bypass the International Court of Justice's Advisory opinion on Western Sahara that had been issued three weeks earlier. Morocco gained control of most of the former Spanish Sahara, which it still holds to this day. The refusal of the Sahrawi people to submit to the Moroccan monarchy gave rise to the Western Sahara conflict, still unresolved today, and whose main episode was the Western Sahara War.

Sahrawi refugees refer to the refugees of the Western Sahara War (1975–1991) and their descendants, who are still mostly populating the Sahrawi refugee camps in Tindouf, Algeria.

Sahrawi nationalism (Arabic: القومية الصحراوية) is a political ideology that seeks self-determination of the Sahrawi people, the indigenous population of Western Sahara. It has historically been represented by the Polisario Front. It came as a reaction against Spanish colonialist policies imposed from 1958 on, and subsequently in reaction to the Mauritanian and Moroccan invasions of 1975.

Its main opposing ideologies have been Spanish colonialism (Spanish Sahara, 1884–1975), Mauritanian irredentism (Tiris al-Gharbiyya, 1975–1979) and Moroccan irredentism (Southern Provinces, 1975-present).
