Santería, also known as Regla de Ocha, Regla Lucumí, or Lucumí, is an Afro-Caribbean religion that developed in Cuba during the late 19th century. It arose amid a process of syncretism between the traditional Yoruba religion of West Africa, Catholicism, and Spiritism. There is no central authority in control of Santería and much diversity exists among practitioners, who are known as creyentes ("believers").
