Guerra de Ifni
Spain attempted to retain control of its colonies throughout Franco's rule. During the Algerian War (1954–62), Madrid became the base of the "Organisation armée secrète" (OAS), a right-wing French Army group which sought to preserve French Algeria. Despite this, Franco was forced to make some concessions. When French Morocco became independent in 1956, he surrendered Spanish Morocco to Morocco, retaining only a few enclaves (the "Plazas de soberanía"). The year after, Mohammed V invaded Spanish Sahara during the Ifni War (known as the "Forgotten War" in Spain). Only in 1975, with the Green March, did Morocco take control of all of the former Spanish territories in the Sahara.
