The Army of Liberation (Moroccan Arabic: Jish Etteḥrir جيش التحرير, Berber: Aserdas Uslelli) was an organisation of various loosely united militias fighting for the independence of Morocco from the French-Spanish occupation.
It was founded sometime in 1955 as an attempt to organise the various factions of rural Moroccan armed resistance that swept the country as a result of the assassination of Farhat Hachad and the exile of king Mohamed ben Youssef.Abdelkrim El Khattabi played an important role in the instigation of the army, through commanders such as Abbas Messaadi and Sellam Ameziane.
In 1956, units of the Army, which started to move its staff from North Spanish Morocco, began infiltrating Ifni and other enclaves of Spanish Morocco, as well as Spanish Sahara (today Western Sahara), to claim them as part of Morocco. Initially, they received important backing from the Moroccan government. In the Spanish Sahara, the Army rallied Sahrawi tribes along the way, and triggered a large-scale rebellion. In early 1958, the Moroccan king reorganized the Army of Liberation units fighting in the Spanish Sahara as the "Saharan Liberation Army", also known as the Southern Liberation Army (Armée de Libération du Sud), sometimes abbreviated as ALS. The ALS had prestigious leaders such as Abderrahmane Youssoufi, Fqih Basri and Bensaid Aït Idder.
The revolt in the Spanish Sahara was put down in 1958 by a joint French and Spanish offensive, known as Operation Ecouvillon or Operation Ecouvillon-Teide. Upon their retreat, the guerrilla fighters were, surprisingly, hindered by the regular Moroccan Army, which allowed Spanish and French forces to neutralize them. The King of Morocco then signed an agreement with the Spanish, where Spain returned the province of Tarfaya (until that agreement, part of Spanish Sahara) to Morocco. Part of the Army of Liberation was absorbed into the Moroccan armed forces.
