The traditional date of the founding of Yoff is 1430. Although they were conquered by the Kingdoms of Jolof (Diolof) and Cayor, and later the French in the 19th century, and were incorporated into modern Senegal, since 1815 they have had a special legal autonomy as a special kind of "theocratic republic".
Lebou society empahasizes piety and respect for elders. Lebou families include not only living people but also associated ancestral spirits. The Lebou are noted for their public exorcism dances and rituals, often attended by tourists.
In addition to Yoff, other Lebou centres are nearby Oakam and Ngor.
