Frankism

Frankism was a Sabbatean religious movement originating in Eastern Europe in the 18th and 19th centuries. 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, such as the infamous 1756 incident in Lanškroun where they were allegedly caught dancing around a half-naked woman symbolizing the Shekhinah.

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. Later, Frankists were encouraged to convert en masse to Catholicism.
