The term was first coined by the Spanish to describe the way West African slaves combined Roman Catholic traditions with aboriginal religious rites. The faith focuses on trances for communicating with ancestors and often involves animal sacrifice. Santeria is practiced in the Caribbean and in some major American cities with significant Caribbean populations. It shares some characteristics with Voodoo, another syncretistic religion in the Caribbean that also traces its roots to West Africa. Santeria is known by several other names, including Lukumi. The name Santeria is actually considered a pejorative by some but has come into common usage, even among some followers, and is acceptable to use. Uppercase Santeria in all references.
