Ruzhin (Hasidic dynasty)
Ruzhin (or Rizhin) is the name of a Hasidic dynasty founded by Rabbi Yisroel Friedman (1796–1850) in the town of Ruzhyn, Ukraine, today an urban-type settlement in Zhytomyr Oblast, Ukraine.
Friedman was the first and only Ruzhiner Rebbe. However, his sons and grandsons founded their own dynasties which are collectively known as the "House of Ruzhin". These dynasties, which follow many of the traditions of the Ruzhiner Rebbe, are Bohush, Boyan, Chortkov, Husiatyn, Sadigura, and Shtefanesht. The dynasties of Vizhnitz and Vasloi are related to the Ruzhiner Rebbe through his daughters.
