Jacob Frank

Jacob Frank (1726–1791) was a Jewish leader who founded the Frankist movement in the 18th century, challenging traditional Jewish beliefs by claiming to be a messianic figure. He emphasized a radical interpretation of Judaism that included antinomian ideas—rejecting conventional religious laws—and sought to blend Jewish mysticism with elements of Christianity. His movement attracted followers among both Jews and Christians, leading to controversy and tension with mainstream Jewish authorities. Frank's teachings significantly influenced Jewish history, particularly in Eastern Europe, and contributed to debates about religious reform and identity during that period.
