Hasidic dynasties are spiritual and social groups within the Hasidic Judaism movement, which originated in the 18th century in Eastern Europe. Each dynasty is led by a Rebbe, a spiritual leader who provides guidance and teachings to their followers. These dynasties often have unique customs, traditions, and interpretations of Jewish law. The most well-known Hasidic dynasties include the Chabad-Lubavitch, Satmar, and Breslov. Each dynasty has its own distinct practices and philosophies, contributing to the rich diversity within Hasidic communities. Followers often maintain close-knit relationships, emphasizing community, prayer, and the study of Torah.
