Forced conversion is adoption of a different religion or irreligion under duress. Some who have been forced to convert may continue, covertly, with the beliefs and practices originally held, while outwardly behaving as converts. Crypto-Jews, crypto-Christians, crypto-Muslims and crypto-Pagans are historical examples of the latter.
The Gypsies cannot be said to have a religion of their own. They have usually adopted the faiths of the countries in which they live. Among the Roma can be found Roman Catholics, Eastern Orthodox, Protestants, and Muslims. Many prefer to carry out religious rituals in their own homes or in the context of folk observances. The best known Romany religious festivals are the annual pilgrimages to Saintes Maries de la Mer on the Mediterranean coast of France and Sainte Anne de Beaupre in Quebec, Canada. In the former, the Roma pay homage to Sara the Black on the 24-26 of May. In Quebec, the Roma pay homage to Saint Anne on July 26. These annual religious festivals serve as social gatherings for the Roma.
