The Battle of Annual(North Eastern Morocco) was fought in 22 July 1921 between the Spanish forces and the Muslims(who lived in Rif, Northern Morocco) under the leadership of Muhammad Ibn Abdul Karim al Khattabi, and was concluded with the victory of Muslims who killed and imprisoned around 16,000 of the Spanish.

The embarrassing defeat of the Spanish forces at Annual created a political earthquake in Spain that subsequently led to General Miguel Primo de Rivera’s coup d’etat of September 13, 1923, the installation of a military dictatorship in Spain (1923–1930) and the eventual collapse of the Spanish Monarchy in April 1931.

Abdul Karim’s guerrilla tactics highly influenced revolutionary leaders like Ho Chi Minh, Mao Zedong and Che Guevara.
