There are the Fulani proper, also referred to as the Fulɓe, including the Pullo (also called the Rimɓe (singular)) and the Dimo, meaning "noble". There is the artisan caste, including blacksmiths, potters, griots, genealogists, woodworkers, and dressmakers. They belong to castes but are "free people". Then there are those castes of captive, slave or serf ancestry: the Maccuɗo, Rimmayɓe, Dimaajo, and less often Ɓaleeɓe, the Fulani equivalent of the Tuareg Ikelan known as Bouzou (Buzu)/Bella in the Hausa and Songhay languages respectively. The Fulani rulers and merchants were, like many other ruling ethnic groups of Africa, also involved in the trans-Atlantic slave trade, sourcing the enslaved people through raids and from captives they took by waging war. Many Fulani were enslaved and raided by ethnic groups who adhere to Traditional African religions.
