History of the Puritans from 1649
From 1649 to 1660, Puritans in the Commonwealth of England were allied to the state power held by the military regime, headed by Lord Protector Oliver Cromwell until he died in 1658. They broke into numerous sects, of which the Presbyterian group comprised most of the clergy, but was deficient in political power since Cromwell's sympathies were with the Independents.
