Vodou developed among Afro-Haitian communities amid the Atlantic slave trade of the 16th to 19th centuries. It arose through the blending of the traditional religions brought to the island of Hispaniola by enslaved West Africans, many of them Yoruba or Fon, and the Roman Catholic teachings of the French colonialists who controlled the island. Many Vodouists were involved in the Haitian Revolution of 1791 to 1804 which overthrew the French colonial government, abolished slavery, and established modern 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.
