Koidanov (also spelled Koidenov) is a Hasidic dynasty founded by Rabbi Shlomo Chaim Perlow (alternately: Solomon Ḥayyim Perlow) in 1833 in the town of Koidanov (present-day Dzyarzhynsk, Belarus). According to the YIVO Encyclopedia of Jews in Eastern Europe, Koidanov was the smallest of the three Lithuanian Hasidic dynasties, the others being Slonim and Karlin-Stolin. On the eve of World War II, its centers of influence were in the regions of Koidanov and Minsk. After its Rebbes and most of its Hasidim were murdered in the Holocaust, the dynasty was re-established in 1948 in Tel Aviv, where it thrives to this day.
