Satmar Hasidism is a branch of Hasidic Judaism founded in the early 20th century by Rabbi Joel Teitelbaum in the town of Satu Mare, Romania. Known for its strict adherence to Jewish law and customs, Satmar emphasizes the importance of community, education, and spiritual devotion. The movement is characterized by its distinctive dress, including black hats and long coats, and its commitment to preserving traditional Jewish practices. Satmar Hasidism is also recognized for its strong opposition to Zionism, believing that the establishment of a Jewish state should only occur with the arrival of the Messiah. The community is primarily based in the United States, particularly in Brooklyn, New York, where it has established numerous institutions, including schools and synagogues, to support its members and promote its values.
