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.
Sadducees
The Sadducees (; Hebrew: "Ṣĕdûqîm") were a sect or group of Jews that was active in Judea during the Second Temple period, starting from the second century BCE through the destruction of the Temple in 70 CE. The sect was identified by Josephus with the upper social and economic echelon of Judean society. As a whole, the sect fulfilled various political, social, and religious roles, including maintaining the Temple. The Sadducees are often compared to other contemporaneous sects, including the Pharisees and the Essenes. Their sect is believed to have become extinct some time after the destruction of Herod's Temple in Jerusalem in 70 CE, but it has been speculated that the later Karaites may have had some roots in—or connections with—Sadducaic views.
