The Sahrawi Arab Democratic Republic (SADR) is a partially recognised state that claims sovereignty over the entire territory of Western Sahara, a former Spanish colony. SADR was proclaimed by the Polisario Front on February 27, 1976 in Bir Lehlu, Western Sahara. The SADR government currently controls about 20-25% of the territory it claims.
It calls the territories under its control the Liberated Territories or the Free Zone. Morocco controls and administers the rest of the disputed territory and calls these lands its Southern Provinces. The SADR government considers the Moroccan-held territory occupied territory, while Morocco considers the much smaller SADR held territory to be a buffer zone.
