Vodou developed among Afro-Haitian communities amid the Atlantic slave trade of the 16th to 19th centuries. Its structure arose from the blending of the traditional religions of those enslaved West and Central Africans, among them Yoruba, Fon, and Kongo, who had been brought to the island of Hispaniola. There, it absorbed influences from the culture of the French colonialists who controlled the colony of Saint-Domingue, most notably Roman Catholicism but also Freemasonry.
Many Vodouists were involved in the Haitian Revolution of 1791 to 1804 which overthrew the French colonial government, abolished slavery, and transformed Saint-Domingue into the republic of Haiti. The Roman Catholic Church left for several decades following the Revolution, allowing Vodou to become Haiti's dominant religion. In the 20th century, growing emigration spread Vodou abroad. The late 20th century saw growing links between Vodou and related traditions in West Africa and the Americas, such as Cuban Santería and Brazilian Candomblé, while some practitioners influenced by the Négritude movement have sought to remove Roman Catholic influences.
