What were the Puritan supports of Oliver Cromwell during the civil war in England called?

The Puritan supporters of Oliver Cromwell during the English Civil War were known as the "Roundheads." This term was used to describe the parliamentary troops and their supporters who opposed King Charles I and the royalist forces, known as the "Cavaliers." The Roundheads were characterized by their more austere and disciplined lifestyle, which was heavily influenced by Puritanism, a religious reform movement that sought to purify the Church of England from its remaining Catholic practices. Cromwell himself was a significant military leader for the Roundheads and played a pivotal role in the Parliament's victory over the monarchy.
