Western Sahara, formerly the Spanish colony of Spanish Sahara, is a disputed territory claimed by both the Kingdom of Morocco and the Popular Front for the Liberation of the Saguia el Hamra and Rio de Oro (Polisario Front), which is an independence movement based in Algeria. The Annexation of Western Sahara by Morocco took place in two stages, in 1976 and 1979, and is considered illegal under international law. Western Sahara is listed by the United Nations (UN) as a non-decolonized territory and is thus included in the United Nations list of non-self-governing territories, which regards Spain as the de jure administering state. Under international law, Western Sahara is not a legal part of Morocco and it remains under the international laws of military occupation. Background Since the Madrid Accords of 1975, a part of Western Sahara has been administered by Morocco as the Southern Provinces. Another section, the Liberated Territories, is administered by the Polisario Front as the Sahrawi Arab Democratic Republic (SADR). Mauritania administers the western half of the Ras Nouadhibou Peninsula. A UN-monitored cease-fire has been in effect since September 1991. While no other country than the United States has ever recognized Morocco's unilateral annexation of Western Sahara, a number of countries have expressed their support for a future recognition of Moroccan sovereignty over the territory as an autonomous part of the Kingdom. There is, for instance, a de facto recognition of the Moroccan claim on the part of some countries such as the case of the United Kingdom. Although the UK Foreign and Commonwealth Office (FCO) treats the status of Western Sahara as 'undetermined', its lack of reference to its current effective partition, considering the existence of the Polisario-held areas, indicates an acceptance of Morocco as the administering power in the entire territory. Overall, the annexation has not garnered as much attention in the international community as many other disputed annexations (e.g. the Russian annexation of Crimea). In order to resolve the sovereignty issue, the UN has attempted to hold a referendum through the United Nations Mission for the Referendum in Western Sahara (MINURSO), and is holding direct talks between the Kingdom of Morocco and the Polisario Front. The UN recognizes neither Moroccan nor SADR sovereignty over Western Sahara. Moroccan settlers currently make up more than two thirds of the 500,000 inhabitants of Western Sahara.
