A biography of the 5th Rebbe of the Lubavitch movement, Rabbi Sholom DovBer Schneersohn. Notwithstanding the tremendous upheavals of the beginning of the 20th century in Czarist Russia, coupled with his frail health, that caused him to be in health resorts, a few months a year, he spearheaded the fight against Czarist Russia's intention of secularising the Jewish community and educational system. He established Yeshivas Tomchei Tmimim, the flagship education system of Lubavitch, and began clarifying the deepest concepts of Chassidus. His communal work included working with the secular Jews to provide the Jewish soldiers with Matza for Pesach during the Russo-Japanese war, as well as saving the Jewish printing press, Rom. As well as protecting the rights of Jews to live where they desire and enter into occupations that could supply them with a livelihood. He established a weaving factory that provided two thousand families with a livelihood. But at the same time, fought with them and upended their efforts to destroy the educational system and replace it with their new, but spiritually dangerous system.His focus was one thing, how to uphold and support Jews and their right to live as Jews, no matter the situation.

It is an honor to present this comprehensive biography, the fifth in The Rabbeim Biography Series.
