There are many narratives, some old, some relatively recent, covering the presence of crypto-Jews in England during the sixteenth and seventeenth centuries. I have tried to give an overview of that story here, which will appear in multiple parts. My account has a particular focus on developments during the English Revolution of 1641–1660, though it is also positioned within a more ambitious grand narrative recounting the Jewish, crypto-Jewish and Jewish apostate experience in England from the Norman Conquest to the Restoration of the Stuart monarchy.
