Before 1727 Whydah was an independent kingdom; after that date it became a province of the Kingdom of Dahomey.

In both conditions it was a great center of the serpent cult; and, being situated on the coast, became (like Badagry) a considerable center also for the European export of slaves to the New World.

These facts have undoubtedly given Whydah a great importance in the development of Haitian voodoo.
