VOODOO AND SHAMANS
Voodoo is a derivative of the world?s oldest known religions which have been around in Africa since the beginning of human civilization. Some conservative estimates these civilizations and religions to be over 10 000 years old.This then identifies Voodoo as probably the best example of African syncretism in the Americas. Although its essential wisdom originated in different parts of Africa long before the Europeans started the slave trade, the structure of Voodoo, as we know it today, was born in Haiti during the European colonization of Hispaniola.
Ironically, it was the enforced immigration of enslaved Africans from different ethnic groups that provided the circumstances for the development of Voodoo.
European colonists thought that by desolating the ethnic groups, these could not come together as a community. However, in the misery of slavery, the transplanted Africans found in their faith a common thread.
They began to invoke not only their own Gods, but to practice rites other than their own. In this process, they comingled and modified rituals of various ethnic groups.
The result of such fusion was that the different religious groups integrated their beliefs, thereby creating a new religion: Voodoo.
"The word "voodoo" comes from the West African word "vodun," meaning spirit."
