The story
Founded by Mikhaʾel Laiṭman in 1991.1
Bnei Baruch is a group teaching Kabbalah in the tradition of the Yehudah Ashlag (Hasidic rabbi). Rabbi Yehuda Ashlag emigrated from Poland to the Yishuv in what was then Palestine in 1921. He wrote a commentary on the Zohar called the Sulam (Ladder). He became very popular in Israel, and was consulted on Kabbalah by the first Prime Minister of the State of Israel, David Ben Gurion. Relying on his claim that the statement “Love thy friend as thyself”, Yehuda Ashlag proposed a theory of "altruistic communism," a form of socialism based on principles of altruism and different from Soviet-style, materialistic communism. '
Yehuda Ashlag died in 1954. After his death, his disciples divided: some followed one of his associates, Yehuda Tzvi Brandwein (1904-1969), who had become Ashlag's brother-in-law through his second marriage. Brandwein's group is, directly or indirectly, at the origins of some contemporary Kabbalah movements, including the Kabbalah Centre of Philip Berg. Other disciples of Yehuda Ashlag accepted the leadership of two of his four sons: Benjamin Shlomo Ashlag (1907-1991), whose group remained comparatively small, and Baruch Ashlag.
In order to fight an attempt by Baruch Ashlag's brother, Benjamin Shlomo Ashlag, to assert his version of their father's work in British courts, Laitman founded Bnei Baruch ("Sons of Baruch"). Gradually, the group developed. Its internal sources report that the breakthrough came in 1997, when the group started offering free Kabbalah courses through the Internet and radio (television followed in 2007), and eventually moved its headquarters from Haredi Bnei Brak to nearby (and more cosmopolitan) Petah Tikvah. Through the Internet, Bnei Baruch started gathering members throughout the world.
