The Sand War grew out of disputed borders inherited from French colonial administration. Morocco claimed portions of the Tindouf and Bechar regions, areas it argued had historically belonged to the Sharifian state before France detached them and attached them to colonial Algeria.
When Algeria became independent in 1962, the new government rejected any revision of the colonial borders, setting the stage for confrontation along an undemarcated frontier.
Skirmishes escalated into open conflict on 25 September 1963, with intense fighting around the oasis towns of Tindouf and Figuig. Both armies engaged over several weeks in difficult desert terrain.
A ceasefire was agreed on 29 and 30 October 1963 in Bamako, Mali, halting the fighting. A formal agreement followed on 20 February 1964 under the auspices of the Organisation of African Unity, providing for withdrawal of forces.
The Bamako framework mandated a ceasefire and the withdrawal of forces to earlier positions, with the OAU establishing a commission to address the dispute. The colonial-era borders were ultimately left largely unchanged.
The episode left Morocco with a grievance over territory it considered historically its own, and it hardened Algerian determination to defend the principle that colonial borders should not be reopened.
The Sand War is often seen as the opening chapter of a lasting Moroccan-Algerian rivalry. The mistrust it generated would later color Algeria's posture on the Western Sahara question after 1975.
Understanding the Sand War helps explain why the Sahara dispute became entangled with broader regional competition rather than remaining a purely bilateral decolonization matter between Morocco and Spain.
It was fought from 25 September to 30 October 1963, with a formal agreement following on 20 February 1964.
It concerned disputed borders in the Tindouf and Bechar regions that Morocco claimed had historically belonged to the Sharifian state.
A ceasefire was reached in Bamako, Mali, on 29-30 October 1963, formalized under OAU auspices in February 1964.
