Voodoo
Another word for voodoo is vodu, used in Haiti where the creole language is based on the French language. African voodoo often has animal sacrifice (the animal is killed for the spirits), but this is not common in Haiti.  Voodoo in Haiti and America has also added some Catholic ideas that were not known in African voodoo. The use of Catholic saints/iconography may have developed as a means of adaptation, and survival, but also as a safety precaution.
