The Toucouleurs or Tukulor (or ) are a group distinct from but related to the Fula. The difference between the Fulbe and the Tukulors is that the latter are a traditionally sedentary group, with farming and fishing as their main activities. Tukulors also live in West Africa, and Fulanis live in Central African countries as well, such as Chad and Cameroon. The north of Senegal (where they constitute 15% of the population) in the Senegal River valley, and Mauritania is their background, but over the past three centuries some of them emigrated to Mali.
