Voodoo is a syncretic religion that originated in West Africa and evolved in the Americas, particularly in Haiti, where it became intertwined with elements of Catholicism. It involves a complex system of beliefs and practices centered on the worship of spirits known as 'Loa,' ancestor veneration, and the use of rituals to heal, protect, and bring about desired changes in one's life. The spread of Voodoo was significantly influenced by the Atlantic Slave Trade, as enslaved Africans brought their spiritual practices to the New World.
