The idea "Puritan" and "Roundhead" were the same thing is incorrect; the term meant anyone who wanted to 'purify' the Church of England of "Papist" practices and covered a wide range of views. While the majority supported Parliament, some like Sir William Savile supported Charles out of personal loyalty. Many Royalists strongly opposed the appointment of Catholic officers, while the integration of Irish troops in 1643 caused some regiments to mutiny. Puritans were also divided between Presbyterians like Pym who wanted to reform the Church of England and religious Independents who rejected the very idea of state-mandated religion. They included Congregationalists like Oliver Cromwell and Baptists.
