When Oliver Cromwell and his fellow Puritans and Parliamentarians wrested control of England, Scotland, and Ireland from King Charles I in the middle of the seventeenth century, they did some really good things for England, like crushing the religious monopoly of the Church of England and putting the British monarchy in its proper place, but there were some regrettable outcomes too.
The first thing Cromwell and the Puritans did was chop off the heads of all the statues in the glorious cathedrals of England, and the second thing they did was to outlaw Christmas.
