After the English Reformation, from the 16th to the 19th century those guilty of such nonconformity, termed "recusants", were subject to civil penalties and sometimes, especially in the earlier part of that period, to criminal penalties. Catholics formed a large proportion, if not a plurality, of recusants, and it was to Catholics that the term initially was applied. Non-Catholic groups composed of Reformed Christians or Protestant dissenters from the Church of England were later labelled "recusants" as well. Recusancy laws were in force from the reign of Elizabeth I to that of George III, but not always enforced with equal intensity.
