Ahmad al-Tijani (1737–1815) was born in Aïn Madhi in present-day Algeria and died in Fes, Morocco. He founded the Tijānī order in the 1780s; sources vary as to the exact date between 1781[1] and 1784.[2] Tijānīs, speaking for the poor, reacted against the then-dominant conservative, hierarchical Qadiriyyah brotherhood, focusing on social reform and grassroots Islamic revival.
