Sadigura is a Hasidic dynasty named for the city of Sadhora (Sadigura in Yiddish), Bukovina, which belonged to Austria. The dynasty began in 1850 with Rabbi Avrohom Yaakov Friedman, a son of Rabbi Yisrael Friedman of Ruzhyn, and was based in Sadigura until 1914. During the interwar period the dynasty was led by Rebbes in Vienna and Przemyśl, Poland, and on the eve of World War II was transplanted to Israel, where it thrives to this day.
Sadigura is one of the branches of the Ruzhiner dynasty, together with Bohush, Boyan, Chortkov, Husiatyn, and Shtefanesht.
As of 2013, Sadigura has several hundred members in Israel and Europe. Its members reside in Israel in Jerusalem, Ashdod, Modiin Ilit, Beitar Ilit, and Elad, and in Europe in London and Antwerp. The dynasty is centered on the current Sadigura Rebbe's beis medrash in Bnei Brak, Israel.
