A Hasidic sect is a group within Judaism that follows the teachings of Hasidism, a spiritual revival movement founded in the 18th century by Rabbi Israel Baal Shem Tov. Hasidic Jews emphasize mysticism, joy in worship, and a close-knit community, often led by a Rebbe, or spiritual leader. Each Hasidic sect has its own customs, traditions, and interpretations of Jewish law, often reflecting the cultural background of its followers. Some well-known sects include Chabad-Lubavitch, Satmar, and Breslov. Hasidic communities are characterized by distinctive dress, including shtreimels and payot, and a strong commitment to religious observance.
