It originated in West Africa and is practiced in various forms across different countries, such as Benin, Togo, and Haiti. Vodou incorporates elements of traditional African beliefs, animism, and syncretism with Catholicism. It involves the veneration of ancestral spirits, deities (loa), and the belief in their influence over human affairs.
