These religions are still alive and well in West Africa. They are recognizable in their descendents, which were adapted to the poverty and enforced Christianization of those who practiced them. Depending on the particular part of the new continent the slaves lived on, their religion became camouflaged and otherwise altered. As with most other non-mainstream religions, persecution was a very real threat and in many places still is. Until very recently, it was extremely difficult for an outsider to learn anything accurate, because secrecy and misdirection were so important in preserving the religions for so long.
