Where was Santeria mostly practiced?

Santería is primarily practiced in Cuba, where it emerged as a syncretic religion blending elements of Yoruba spirituality from West Africa with Roman Catholicism. It has also spread to other parts of the Caribbean, the United States, and various Latin American countries, largely due to migration. The religion involves rituals, offerings, and the veneration of Orishas, which are deities representing various aspects of life and nature.
