Espiritismo (Portuguese and Spanish for "Spiritism") is a term used in Latin America and the Caribbean to refer to the popular belief that evolved and less evolved spirits can affect health, luck and other aspects of human life. The phenomenon and broad range of beliefs defined as "Espiritismo" originated with the ideas of Spiritism defined by Allen Kardec. His Spiritism would become popular in Latin America and influence existing religions as well as forming Africanized traditions of Espiritismo itself. It would become especially prominent in Brazil, Cuba, and Puerto Rico. Scientific White Table Espiritismo would develop from a loose understanding of Kardec's philosophy. During the Ten Years' War in Cuba much of the population was in panic and grieving from the loss of loved ones. White Cubans were able to alleviate some of their emotional pain by turning to Espiritismo which allowed them to commune with dead loved ones. White espiritistas would ask their Congolese slaves to guide them in Espiritismo de Cordon ceremonies. In the early 1800s, Espiritismo would gain popularity in Puerto Rico because of the populace's rejection of Spanish hegemony and Spiritism's condemnation by the colonial Catholic Church. Originally brought to the country from Puerto Ricans studying in Europe the White Table Espiritismo practiced by the upperclass would help evolve a more creolized Indigenous Espiritismo among the underclass. Researcher Marta Moreno Vega suggests Puerto Rican Espiritismo became popular as a way to mimic ancestor veneration in Kongo religion. Espiritismo in Cuba would eventually mix with other local African elements and produce Espiritismo Cruzao which would gain in popularity in the early 1900s. By the Cuban Revolution espiritista practices became banned and pushed underground but still retain a presence in Cuban society to this day. Cuban Americans and Puerto Rican Americans residing in New York and New Jersey began to meld the beliefs of Santeria and Espiritismo which became Santerísmo.
