The term "Frankists" refers to followers of Jacob Frank, an 18th-century religious leader who claimed to be the Messiah. Frank founded a sect that combined elements of Judaism and Christianity, promoting a controversial belief system that challenged traditional Jewish teachings. His followers believed in the necessity of breaking religious laws to achieve spiritual redemption. The Frankist movement emerged in Eastern Europe and gained a following among some Jewish communities. However, it faced significant opposition from mainstream Jewish authorities, leading to its decline after Frank's death in 1791. Today, the Frankists are often studied for their unique blend of religious ideas and their impact on Jewish history.
