The term "Frankist" refers to followers of the teachings of Jacob Frank, an 18th-century religious leader who founded a sect within Judaism. Frankism emerged as a controversial movement that combined elements of Jewish mysticism, particularly Kabbalah, with radical ideas about religious practice and belief. Frank claimed to be the Messiah and promoted a unique interpretation of Jewish law, which included the idea of transgressing traditional boundaries to achieve spiritual redemption. Frankists believed in the necessity of embracing sin as a means to attain a higher spiritual state. This belief led to significant tensions with mainstream Jewish communities, resulting in the ostracism of Frankists. The movement eventually declined after Frank's death in 1791, but it left a lasting impact on discussions about Messianism and religious reform within Judaism.
