Muḥammad bin ‘Abd al-Karīm al-Khaṭṭābī, better known as Abd el-Krim (Arabic: عبد الكريم; 1882 or 1883 – 6 February 1963), was a Moroccan political and military leader and the president of the Republic of the Rif. He and his brother M'Hammad led a large-scale revolt by a coalition of Riffian tribes against the Spanish and French Protectorates of the Rif and the rest of Morocco. His guerrilla tactics, which included the first-ever use of tunneling as a technique of modern warfare, directly influenced Ho Chi Minh, Mao Zedong and Che Guevara. He also became one of the major figures of Arab nationalism, which he actively supported.
