Voodoo

Voodoo is an African-American religion practised in the Caribbean and the Southern states of North America, combining elements of Roman Catholic beliefs with traditional African magical and religious rites, and characterized by sorcery and spirit possession. Voodoo was brought in the colonies by African slaves (Angelique's Descent). 
The word "voodoo" is generally used as a synonymous for black magic used by witches and warlocks. Especially when they use dolls to control their victims. Quentin Collins invoked the "Voodoo Gods" and makes a clay voodoo doll to attack Barnabas Collins (718).
==Voodoo in Secondary Dark Shadows Media==
Voodoo has a predominant role in the novel Angelique's Descent written by Lara Parker. In the novel, Angelique is taught Voodoo magic by an enslaved African priest, and she is worshipped as the reincarnation of a Voodoo goddess of love and beauty by the slaves working at a plantation in Martinique.
In the 1991 revival series of Dark Shadows, Countess Natalie du Prés mentions to Barnabas Collins that Angelique's mother was as a woman skilled in Voodoo, but it is only in the novel written by Lara Parker that Angelique's voodoo background is amply described.
