The Fulani and Hausa people have taken some influences from each other's cultures. Upon the success recorded in the 1804 Fulani War of Usman dan Fodio, many of Fulɓe subsequently joined the ruling classes of the Northern Nigerian Emirate. They dress and speak like their Hausa neighbours and live in the same form (see Hausa–Fulani). The Fulɓe who didn't settle during this period and their descendants, however, still keep an obvious distinct identity from that of the Hausa and other surrounding groups of the region. This Hausa–Fulani interaction is uncommon outside the eastern subregion of West Africa.
