Western Sahara (/ (
Arabic: الصحراء الغربية aṣ-Ṣaḥrā’ al-Gharbīyah,
Berber languages: Taneẓroft Tutrimt,
French: Sahara Occidental) is a
disputed territory in the
Maghreb region of
North Africa, partially controlled by the self-proclaimed
Sahrawi Arab Democratic Republic and partially Moroccan-
occupied, bordered by
Morocco proper to the north,
Algeria to the northeast,
Mauritania to the east and south, and the
Atlantic Ocean to the west. Its surface area amounts to 266,000 square kilometres (103,000 sq mi). It is one of the
most sparsely populated territories in the world, mainly consisting of desert flatlands. The population is estimated at just over 500,000,
 of which nearly 40% live in
Laayoune, the largest city in Western Sahara.
Spain until the late 20th century, Western Sahara has been on the
United Nations list of non-self-governing territories since 1963 after a Moroccan demand.
 It is the most populous territory on that list, and by far the largest in area. In 1965, the
UN General Assembly adopted its first resolution on Western Sahara, asking Spain to decolonise the territory.
 One year later, a new resolution was passed by the General Assembly requesting that a referendum be held by Spain on self-determination.
 In 1975, Spain relinquished the administrative control of the territory to a joint administration by Morocco (which had formally claimed the territory since 1957)
 and Mauritania.
 A war erupted between those countries and a
Sahrawi nationalist movement, the
Polisario Front, which proclaimed the
Sahrawi Arab Democratic Republic (SADR) with a
government in exile in
Tindouf, Algeria. Mauritania withdrew its claims in 1979, and Morocco eventually secured de facto control of most of the territory, including all the major cities and natural resources. The United Nations considers the Polisario Front to be the legitimate representative of the Sahrawi people, and maintains that the Sahrawis have a right to
United Nations-sponsored ceasefire agreement in 1991, two thirds of the territory (including most of the Atlantic coastline - the only part of the coast outside the
Moroccan Western Sahara Wall is the extreme south, including the
Ras Nouadhibou peninsula) has been administered by the Moroccan government, with tacit support from France and the United States, and the remainder by the SADR, backed by Algeria.
 Internationally, countries such as
Russia have taken a generally ambiguous and neutral position on each side's claims, and have pressed both parties to agree on a peaceful resolution. Both Morocco and Polisario have sought to boost their claims by accumulating formal recognition, essentially from African, Asian, and Latin American states in the developing world. The Polisario Front has won formal recognition for SADR from
37 states, and was extended membership in the
African Union. Morocco has won support for its position from several African governments and from most of the
Muslim world and
 In both instances, recognitions have, over the past two decades, been extended and withdrawn according to changing international trends.
As of 2017member state of the United Nations has ever officially recognized Moroccan
sovereignty over parts of Western Sahara.
 However, a
number of countries have expressed their support for a future recognition of the Moroccan annexation of the territory
as an autonomous part of the Kingdom. Overall, the annexation has not garnered as much attention in the
as many other disputed annexations (e.g.
the Russian annexation of Crimea).
