Hausa–Fulani is a term used to refer collectively to the Hausa and Fulani people of West Africa. The two are grouped together because since the Fulani War their histories have been largely intertwined. For example, when the Fulani took over Hausa city-state of Kano during the Fulani War, the new emirs ended up speaking the Hausa language instead of Fulfulde.
The Hausa–Fulani are one out of Nigeria's three major ethnic groups (alongside the Yoruba and Igbo (Ibo)). The Hausa–Fulani account for 29% of Nigeria's population.
