The ethnogenesis of the Fulani people may have begun as a result of interactions between an ancient West African population and North African populations such as Berbers or Egyptians. Their West African roots may be in and around the valley of Senegal River. They likely reflect a genetic intermix of people with West African, North African, and Arabian origins, and have been a part of many ruling dynasties particularly in the Sahel and West Africa. Speculations about their origins started in the era of European conquest and colonization.
