The Ceddo, also spelled Cedo, Tieddo, or Tyeddo, were a class of warrior-slaves in pre-colonial Senegambian societies, particularly Jolof, Cayor, Baol and Waalo. Up until the mid 19th century, they were a powerful political and social group closely aligned with the traditional monarchs of the region against the rise of Islam and colonialism. In modern-day Senegal the word retains negative connotations, and can describe the societies in which the ceddo operated or the followers of traditional African religions generally.[1]
