Sadigura is a Hasidic dynasty named for the city of Sadhora, Bukovina, which was part of the Austrian Empire. 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 just before World War II moved to Israel.

Avrohom Yaakov Friedman was the first Rebbe of the Sadigura Hasidic dynasty. He lived in the palatial home constructed by his father, Rabbi Yisrael Friedman of Ruzhyn, who fled to the Austrian town of Sadhora due to persecution by the Russian Tsar. He maintained his father's extravagant lifestyle while immersing himself in Torah study and mysticism. He was considered the greatest Rebbe of his era, attracting hundreds of thousands of Jews as well as prominent Christian leaders to his court.
