Summary
In 1975, King Hassan II of Morocco organized a massive nonviolent march of 350,000 Moroccans into the Western Sahara to claim the territory for Morocco. The march, known as the Green March, lasted four days and pushed ten kilometers into the region before being called back. It led to the Madrid Accords, which gave Morocco joint control over the territory and eventually full control after Spain withdrew.
Background
Morocco had claimed the Spanish Sahara (Western Sahara) since its independence in 1956, based on historical allegiances and the discovery of phosphate mines. Spain was under UN pressure to decolonize and faced guerrilla warfare from POLISARIO, making it willing to relinquish control by 1975.
What happened
On October 16, 1975, the International Court of Justice ruled that the people of Spanish Sahara should have self-rule, opposing Morocco’s claim. [source: nv-database] That night, King Hassan II announced a ‘Green March’ to reclaim the territory, mobilizing 350,000 volunteers, including 306,500 civilians and 43,500 government officials [source: nv-database]. On October 31, King Hassan deployed troops to the border to prevent external interference, while volunteers gathered in Tarfaya [source: nv-database]. On November 6, the march began, with participants carrying pictures of the king, the Qur’an, and flags of Morocco, Jordan, the US, and Saudi Arabia [source: nv-database]. Spanish troops were ordered not to attack to avoid a massacre [source: nv-database]. The march continued for four days until November 9, advancing ten kilometers into Western Sahara, after which King Hassan called the volunteers back unharmed [source: nv-database]. On November 14, the Madrid Accords gave Spain, Morocco, and Mauritania joint control until Spain’s full withdrawal in 1976 [source: nv-database]. The region remains disputed, with many Sahrawi living in refugee camps in Algeria [source: nv-database].
Key people & organizations
- King Hassan II
- POLISARIO
Tactics used
The nonviolent invasion created a dilemma for Spain, which could not attack unarmed civilians without international condemnation, while the massive scale and religious symbolism of the march demonstrated popular support and pressured Spain into negotiations. [source: nv-database]
Outcome
Verdict: partial.
The march did not immediately achieve Moroccan control but led to the Madrid Accords and eventual Moroccan takeover, though the native Sahrawi people’s right to self-determination remains unresolved, making the outcome partial. [source: nv-database]
Lessons
- A massive nonviolent invasion can create a strategic dilemma for an occupying power, forcing negotiations.
- Religious and national symbols can mobilize large numbers of participants and build legitimacy.
- Even in conflicts involving territorial conquest, nonviolent action can be effective when combined with military deterrence.
