Explanation: During the English Civil War, a conflict between Parliamentarian and Royalist forces raged across the country. Eventually, Parliamentarian forces, themselves dominated by radical protestants known as "Puritans", would prevail in the war, with their primary military leader, Oliver Cromwell, ascending to power.
Unfortunately, Cromwell was the worst mixture of radicalism - none of the pro-democracy or proto-socialist sentiment common amongst Parliamentarian radicals, all of the religious fanaticism! He dissolved parliament and ruled as a dictator, enforcing measures against "popery" like "entertainment", "Fun", and "Irish people being alive".
