Spiritism or Kardecism is a reincarnationist and spiritualist doctrine established in France in the mid-19th century by writer and educator Hippolyte Léon Denizard Rivail. Kardec considered his doctrine to derive from a Christian perspective. He described a cycle by which a spirit supposedly returns to material existence after the death of the old body in which it dwelled, as well as the evolution it undergoes during this process. Kardecism emerged as a new religious movement in tandem with spiritualism, the notions and practices associated with spiritual communication disseminated throughout North America and Europe since the 1850s.

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, the Roman Catholic form of Christianity, and Spiritism. There is no central authority in control of Santería and much diversity exists among practitioners, who are known as creyentes ("believers").
