Voodoo is far different from the frightening primal and darkly twisted religion that is portrayed in popular culture. It is an over-arching term for the different types of tribal religions developed by Africans as their religions were affected by the influence of Christianity while in Africa and as they were forced to adjust their practices while in slavery. There are three main types of Voodoo: West African, Haitian, and Louisiana. West African is considered by many to be the purist form of voodoo, while Haitian and Louisiana voodoo are much more hybrid. It is important to note that Voodoo is not the same as Hoodoo, though many people use the terms inter-changeably (and often in a derogatory fashion). Hoodoo is little more than folk magic, using the techniques of the Congo people but lacking any of the important religious elements of it.
