Haitian Voodoo is an established religion that originated in Haiti. Voodoo was established by African slaves brought to Haiti in the 1500's and who still tried to follow their traditional African beliefs. Practitioners are described as Vodouisants.
The principal belief in Haitian Voodoo is that deities called Loa service a god called Bondyè, This supreme being does not deal with humans, and it is to the Loa that Voodoo practitioners direct their worship.

For example, the northern area of Haiti has been influenced by numerous Kongo practices.
