Koidanov (Hasidic dynasty)

Reb Baruch Mordechai's was succeeded by his eldest son, Rabbi Aharon Perlow (1839–1897), who was among the most influential rebbes of Koidanover Hasidism.

Reb Baruch Mordechai younger son was Rabbi Shalom Perlow (1850–1925) who headed the Koidanover community in Lida.

He established several Koidanover communities across Lithuania and Belarus and attracted thousands of followers due to his charismatic leadership.

He strengthened the Koidanover community founded in Tiberias, and supported settlement in the Land of Israel but spoke strongly against the tenets of political Zionism.

He published and annotated a number of classic kabbalah works, including Rabbi Moshe Cordovero's Or Ne'erav, to which he appended his commentary Nir'eh Or (1899), and Rabbi Moshe Hagiz' Sefat Emet, which he supplemented with teachings on the significance of the Land of Israel in kabbalistic and Hasidic works (1876).

He also authored a siddur entitled Seder Tefilot Yisrael Or Hayashar ("The Direct Light: Order of Prayers of Israel"), in which he enumerated "eight mystical practices for spiritual perfection".

To combat this, Reb Yosef built a large yeshiva called Tomchei Tzedek to bring Jews away from the Haskalah and towards Orthodoxy.

[6] Under Rabbi Yaakov Tzvi Meir Ehrlich's direction, the Koidanover dynasty maintains synagogues in Tel Aviv and Bnei Brak and a yeshiva, in addition to chesed projects.

His beis medrash, is located in Dizengoff Square and serves as an outreach center where weekly lectures and a Friday-night Oneg Shabbat attract many secular Jews and guide them towards religious observance.
