The Sahrawi Arab Democratic Republic (SADR) is a partially recognized state that claims sovereignty over the territory of Western Sahara. It was proclaimed by the Polisario Front in 1976, following Spain's withdrawal from the region. The SADR seeks independence for the Sahrawi people and operates from refugee camps in Algeria. The SADR is recognized by some countries and is a member of the African Union. However, its sovereignty is disputed by Morocco, which claims the territory as part of its national borders. The ongoing conflict has led to a protracted struggle for self-determination for the Sahrawi people.
