The alleged or actual preservation of
Jewish rites[?] by converted
Jews or their descendants,
crypto-Judaism was a particular target of the
Inquisition. Crypto-Jews were sometimes called
Marranos as a derogatory term.
Small communities of descendants of crypto-Jews can still be found in Spain, Portugal, the Caribbean, Iran, and the American Midwest[?].
