The Green March was a strategic mass demonstration in November 1975, coordinated by the Moroccan government, to force Spain to hand over the disputed, autonomous semi-metropolitan province of Spanish Sahara to Morocco.

The demonstration of some 350,000 Moroccans advanced several kilometers into the Western Sahara territory, escorted by nearly 20,000 Moroccan troops, meeting very little response by the Sahrawi Polisario Front.

Nevertheless, the events quickly escalated into a fully waged war between Morocco and the militias of the Polisario, the Western Sahara War, which would last for 16 years. Morocco later gained control over most of the former Spanish Sahara, which it continues to hold.
