Berditchev (Hasidic dynasty)
Berditchev Hasidim, also known in Yiddish as Berditchiver Hasidim, originated in the town of Berdychiv, which over the years was under the control of Lithuania, Poland, Russia, and Ukraine.
During the 18th century Berditchev was an important center of Hasidism. Rabbi Levi Yitzchok of Berditchev (1740-1810), also known as the Kedushat Levi in honor of his great Talmudic and pietistic work, became the inspiration for subsequent generations of Berditchiver Hasidim.
Today, there are several synagogues called Berditshev, of which the rabbis of some are called Berditshever Rebbes.
