Both Zarma and Hausa areas were greatly influenced by the 18th- and 19th-century Fula led Sufi brotherhoods, most notably the Sokoto Caliphate (in today's Nigeria). Modern Muslim practice in Niger is often tied to the Tijaniya Sufi brotherhoods, although there are small minority groups tied to Hammallism and Nyassist Sufi orders in the west, and the Sanusiya in the far northeast.
