Some slaves brought traditional beliefs and practices, especially related to Islam and in some instances magic, with them from Africa. No organized African religious practices are known to have taken place in the Thirteen Colonies, but Muslims practiced Islam surreptitiously or underground throughout the era of the enslavement of African people in America. The story of Abdulrahman Ibrahim Ibn Sori, a Muslim prince from West Africa who spent 40 years as a slave in the United States from 1788 onwards before being freed, demonstrates the survival of Muslim belief and practice among enslaved Africans in America.
