In 1914, with the outbreak of World War I, Rabbi Avrohom Yaakov fled to Vienna together with his younger brother, Rabbi Shlomo Chaim, and his orphaned nephew, Rabbi Mordechai Sholom Yosef. Rabbi Avrohom Yaakov established his court in Vienna and led the Sadigura Hasidim from that city for the next 24 years.Friedman, The Golden Dynasty, pp. 38–39. The relocation of the Sadigura Rebbes to Vienna effectively put an end to the once-flourishing Jewish community in Sadigura, which comprised more than 5,000 Jews before World War I. The remaining Jews of the town were decimated by the Nazis during World War II.
