Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
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.
