Western Sahara is the last territory in Africa recognised by the United Nations as non-self-governing.
Spanish colonial occupation was ended in 1975 by the struggle of the Polisario Front. However, independence was denied by a secret agreement between Spain and Morocco for a Moroccan invasion.
Since the invasion about half the Saharawi population have lived in refugee camps on the border with Algeria while the remainder living under Moroccan occupation are becoming outnumbered by Moroccan settlers.
