Western Sahara is on the United Nations list of Non-Self-Governing Territories, meaning that in the UN's eyes, the territory has not been decolonized.
The Kingdom of Morocco and the Sahrawi Arab Democratic Republic (SADR) presently dispute the control of the territory, Morocco claiming the Sahara as an integral part of the kingdom, while the SADR is a government in exile, controlling a minority of the territory. The rest is controlled and the entirety claimed by Morocco.
