Imam Shamil
Sufism suffered setbacks in North Africa during the colonial period; the life of the Algerian Sufi master Emir Abd al-Qadir is instructive in this regard. Notable as well are the lives of Amadou Bamba and Hajj Umar Tall in sub-Saharan Africa, and Sheikh Mansur Ushurma and Imam Shamil in the Caucasus region.
