Jewish conversions to Christianity in Eastern Europe were infrequent in both premodern and modern times. Mass conversions to Christianity occurred at two intervals: to Eastern Orthodoxy during the Khmel’nyts’kyi uprising (1648–1649; gzeyres takh vetat), and to Catholicism by followers of Jakub Frank in the second half of the eighteenth century. Jewish and Christian sources suggest that individual conversions to Judaism also took place.
