Forced conversion
Forced conversion is the adoption of a religion or irreligion under duress. Someone who has been forced to convert to a different religion or irreligion may continue, covertly, to adhere to the beliefs and practices which were originally held, while outwardly behaving as a convert. Crypto-Jews, Crypto-Christians, Crypto-Muslims and Crypto-Pagans are historical examples of the latter. Provided by Wikipedia-
