The Fula people or Fulani or Fulɓe (; ; ; ; ; ) are one of the largest ethnolinguistic groups in Africa, numbering approximately 40 million people in total. They are one of the most widely dispersed and culturally diverse of the peoples of Africa. The Fulani are bound together by the common language of Fulfulde, as well as by some basic elements of Fulbe culture, such as The pulaaku , a code of conduct common to all Fulani groups. A significant proportion of their number, (an estimated 13 million), are nomadic, making them the largest pastoral nomadic group in the world. Spread over many countries, they are found mainly in West Africa and northern parts of Central Africa, but also in Sudan and Egypt.
