Louisiana Voodoo (French: Vaudou louisianais, Spanish: Vudú de Luisiana, Louisiana Creole: Voudou Lalwizyàn), also known as New Orleans Voodoo, is an African diasporic religion and magic tradition that originated in Louisiana. It arose through a process of syncretism between the traditional religions of West Africa, the Roman Catholic form of Christianity, and Haitian Vodou. No central authority is in control of Louisiana Voodoo, which is organized through autonomous groups.
Historical records reveal the names of various deities who were worshiped in Voodoo. Prominent among them were Blanc Dani, the Grand Zombi, and Papa Lébat. These were venerated at altars, where sacrifices were made to them. Spirits of the dead also played a prominent role in historical Voodoo, with some contemporary practitioners regarding the religion as a form of ancestor worship. Historical accounts suggest that in the 19th century, the saints played a prominent role, although amid the 20th-century revival, the veneration of deities from other African diasporic religions became common. The production of charms, which are known as gris-gris, plays an important part.
From the early 18th century, enslaved West Africans—the majority of them Bambara and Kongo—were brought to the French colony of Louisiana. There, their traditional religions would have syncretized with the Roman Catholic beliefs of the French. This continued as Louisiana came under Spanish control and was then purchased by the United States in 1803. In the early 19th century, many migrants fleeing the Haitian Revolution arrived in Louisiana, bringing with them Haitian Vodou, which contributed to the formation of Louisiana Voodoo. Although the religion was never banned, its practice was restricted through a range of laws regulating when and where black people could gather. Practiced secretly, it spread up the Mississippi River to Missouri. During the 19th century, practitioners such as Marie Laveau, attracted considerable attention. By the early 20th century, the public practice of Voodoo had heavily declined. After the 1960s, the New Orleans tourist industry increasingly used references to Voodoo to attract visitors, while a Voodoo revival took place, the practitioners of which often drew heavily on other African diasporic religions such as Haitian Vodou and Cuban Santería.
Although originating among African diasporic communities in New Orleans, Louisiana Voodoo has included white participants since at least the 19th century, and some contemporary Voodoo groups have a majority-white membership. The religion has long faced opposition from non-practitioners, who have characterized it as witchcraft and devil-worship, and many sensationalist portrayals of the religion have featured in popular culture.
