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.
Judaism
Over a long time, Jews formed distinct ethnic groups in several different geographic areas—amongst others, the Ashkenazi Jews (of central and Eastern Europe), the Sephardi Jews (of Spain, Portugal, and North Africa), the Beta Israel of Ethiopia, and the Yemenite Jews from the southern tip of the Arabian Peninsula. Many of these groups have developed differences in their prayers, traditions and accepted canons; however, these distinctions are mainly the result of their being formed at some cultural distance from normative (rabbinic) Judaism, rather than based on any doctrinal dispute.
