Voodoo is animism or spiritism. That is, all aspects of the natural world are seen as having spiritual identity immune to physical death. Animism includes belief in a person's spirit surviving the death of the body. Ancestors' 'spirits' are called upon for inspiration, protection or other influences over the material world. The roots of voodoo in the Americas come from the Fon, Ewe, and Yoruba people of Africa.. The word vodún is the Fon-Ewe word for spirit.
