With the signing of the Madrid Accords, Spain abandons Western Sahara.

The Madrid Accords, formally the Declaration of Principles on Western Sahara, was a treaty between Spain, Morocco, and Mauritania setting out six principles which would end the Spanish presence in the territory of Spanish Sahara and arrange a temporary administration in the area pending a referendum.

Western Sahara is a non-self-governing territory in North-western Africa undergoing decolonization. It has a surface area of 272,000 square kilometres (105,000 sq mi). Western Sahara is the last African colonial state yet to achieve independence and has been dubbed "Africa's last colony". With an estimated population of around 600,000 inhabitants, it is the most sparsely populated territory in Africa and the second most sparsely populated territory in the world, consisting mainly of desert flatlands.
