Frankism was a Sabbatean religious movement originating in the Polish–Lithuanian Commonwealth in the 18th and 19th centuries.[1] Created in Podolia, it was named after its founder, Jacob Frank.

Frank completely rejected Jewish norms, preaching to his followers that they were obligated to transgress moral boundaries, embracing antinomianism. The Frankists engaged in incest, orgies and sex rituals

At its height, Frankism claimed perhaps 50,000 followers, primarily Jews living in the Polish–Lithuanian Commonwealth, as well as in other regions of Central and Eastern Europe.

Jacob Frank claimed to be a reincarnation of Sabbatai Zevi and followed and extended his practice of transgression. Father-daughter incest was commonly practised by his followers,[10] and orgies featured prominently in ritual.[4][5][11] Frank claimed that "all laws and teachings will fall",[12] and following antinomianism, asserted that the most important obligation of humanity was the transgression of every boundary.
