But dynasties do not last for ever, and every royal family begins with a usurper or foreign conqueror. Usually religion legitimizes the new family by means of some traditional ceremony.

"No Bishop, no King," said Charles I, and the analogue of this maxim has been true in all ages in which kings have existed.
