The Kosov Hasidic dynasty, Rabbi Mendel of Kosov's descendants, founded the many Kosov Hasidic sects. The Vizhnitz dynasty is the best known branch of the original Kosover dynasty. Other branches include Seret.
Among the many contemporary descendants of the Kosov dynasty, two are called "the Kosover Rebbe": Rabbi Shraga Feivish Hager of Borough Park, Brooklyn, where he has a substantial following and presides at his tish, and Rabbi Menachem Monderer of Jerusalem (died 2013).[1] There is also a historic Kosover synagogue in Tzfas (Safed), Israel, which, however, is run by followers of the Biala Rebbe of Lugano, Switzerland.
