Black Judaism
Black Judaism is the collective term used to describe sects of Judaism predominantly practiced by the members of the African communities, both within the African Continent and outside Africa (such as North America). It is theologically characterized by the selective acceptance of the Judaic faith (in some cases such selective acceptance has historical circumstances), and that the belief system of Black Judaism is significantly different from the mainstream sects of Judaism. In addition, although Black Judaic communities adopt Judaic practices such as Jewish holidays and Jewish prayers, they are generally not recognized by the mainstream Jewish societies as legitimately Jewish.
African-American culture
There are 150,000 African Americans in the United States who practice Judaism. Some of these are members of mainstream Jewish groups like the Reform, Conservative, or Orthodox branches of Judaism; others belong to non-mainstream Jewish groups like the Black Hebrew Israelites. The Black Hebrew Israelites are a collection of African-American religious organizations whose practices and beliefs are derived to some extent from Judaism. Their varied teachings often include, that African Americans are descended from the Biblical Israelites.
