Introduction
Western Sahara is a disputed territory on the northwest coast of Africa, bordered by Morocco, Algeria, and Mauritania. With a population of over 500,000, it remains one of the most enduring unresolved conflicts in international relations, rooted in decolonization and competing claims over sovereignty and self-determination.
The Parties to the Conflict

1. Morocco:
Morocco considers Western Sahara an integral part of its southern provinces and currently controls about 80% of the territory, including major cities, coastlines, and natural resources.
2. Polisario Front:
A nationalist liberation movement representing the Sahrawi people, seeking full independence. It controls roughly 20% of the territory, often referred to as the “Liberated Territories,” with support and refuge in Algeria.
Territorial Division
Morocco has constructed a fortified sand wall known as the “Berm,” which separates the Moroccan-controlled areas from the Polisario-controlled zones.
- Moroccan zone: sometimes called the “useful triangle” due to its economic value
- Polisario zone: referred to as the “Free Zone” or “Liberated Territories”
Origin of the Conflict
The roots of the conflict lie in decolonization:
- 1956: After gaining independence, Morocco claimed Western Sahara (then Spanish Sahara) as part of its historical territory.
- 1960s–1970s: Spain maintained colonial control over the territory.
- 1973: The Polisario Front was formed to end Spanish rule and secure independence.
- 1975: Spain withdrew following the Madrid Accords, transferring administrative control to Morocco and Mauritania.
- 1975–1979: Polisario fought both Morocco and Mauritania; Mauritania later withdrew its claim in 1979.
- 1976: Polisario declared the Sahrawi Arab Democratic Republic (SADR).
Armed Conflict and Ceasefire
- 1973–1991: Armed struggle between Morocco and Polisario, mainly guerrilla warfare.
- 1991: A ceasefire was brokered by the United Nations, which established MINURSO to organize a referendum on self-determination.
- The referendum has not been held due to disagreements over voter eligibility and political conditions.
Current Situation
- Morocco controls most of Western Sahara and proposes autonomy under its sovereignty.
- The Polisario Front insists on a referendum that includes the option of full independence.
- Tensions occasionally flare despite the ceasefire framework, and the political process remains stalled.
Key Issues in International Relations
The Western Sahara conflict highlights several core IR themes:
- Decolonization and unfinished colonial legacies
- Self-determination vs. territorial integrity
- Regional rivalry, especially between Morocco and Algeria
- Challenges of global governance, particularly the limits of UN peacekeeping and mediation
Conclusion
The case of Western Sahara remains a complex and unresolved dispute shaped by historical claims, nationalist aspirations, and geopolitical interests. Despite decades of UN involvement, a lasting solution has yet to be achieved, making it a significant example of the difficulties in balancing sovereignty and the right to self-determination in the international system.
