 After the Green March pressure and the Madrid Accords of 1975, Spain unilaterally disengaged itself leaving the territory to Morocco and Mauritania, who split the territory, giving two thirds to the former, in a movement that was not recognized by the UN.The Polisario Front rejected this illegal move and declared in Bir Lehlou, the Sahrawi Arab Democratic Republic (SADR) as the state representing an independent Western Sahara.In 1979, Mauritania signed a peace treaty with the Polisario front, and Morocco annexed the part formerly controlled by Mauritania.
