In terms of religious and spiritual practice, the 18th century saw the development of Hasidic Judaism. Stemming from the teachings of the Baal Shem Tov and drawing on the traditions of Kabbalah, Hasidic Judaism emphasized emotion and religious ecstasy over the academic dogmatism that had previously come to define Orthodox Judaism in Eastern Europe. During this time period, the Jewish community of Poland would also experience the tail-end of Sabbatianism in the form of the followers of Jacob Frank, who claimed to be a successor of Sabbatai Zevi.
