usman dan fodio and the sokoto caliphate

By the late eighteenth century in Nigeria, many Muslim scholars and teachers had become disenchanted with the insecurity that characterized the Hausa states and Borno. Some clerics (mallams) continued to reside at the courts of the Hausa states and Borno, but others, who joined the Qadiriyah brotherhood, began to think about a revolution that would overthrow existing authorities. Prominent among these radical mallams was Usman dan Fodio, who with his brother and son, attracted a following among the clerical class.
