Rebbe Avraham Yaakov Friedman (the first) of Sadigura (1819-1883) was a prominent Rebbe and Jewish leader in his generation. He was the son and successor of R. Yisrael of Ruzhin in his Beit Midrash in Sadigura (Sadhora), the son-in-law of R. Aharon of Karlin the Beit Aharon, and from his second marriage, of R. Menachem Nachum of Shtefanesht. In Elul 1851, he was appointed Rebbe of Sadigura, in place of his father (who passed away in Cheshvan 1850) and of his eldest brother R. Shalom Yosef (who passed away Elul 11, 1851).
He served as rebbe for close to 32 years, leading a court of thousands of Chassidim and pious men. Many flocked to receive his blessings, guidance and counsel. He concealed his holiness, and only by chance was it revealed that he dealt extensively in helping the deceased attain a reparation for their soul. He conducted himself with majestic opulence and lavishness, as was customary in the Ruzhin dynasty, yet he himself was holy and ascetic, eating so little that his intestines shriveled up. He stood at the helm of Orthodox Jewry of his generation, and joined Rebbe Yehoshua of Belz under the Machzikei HaDat organization in Galicia. At his initiative, the magnificent Tiferet Yisrael synagogue in Jerusalem was completed. In his public activism, he maintained ties with prominent figures in international politics, including Sir Moses Montefiore and the British diplomat Laurence Oliphant, who came to Sadigura specifically to meet him (Derech Malchut, p. 456). He suffered the Russian government's persecution of the Ruzhin dynasty, and after he addressed a letter to Montefiore requesting his intervention in saving Russian Jewry from the Russian Tsar, he was denounced to the government of the Austro-Hungarian empire under trumped up charges of counterfeiting money, which led to his incarceration for almost two years (between 1856-1858).
