A monarchy is the most expensive of all forms of government, the regal state requiring a costly parade, and he who depends on his own power to rule, must strengthen that power by bribing the active and enterprising whom he cannot intimidate. – James Fenimore Cooper
The best reason why Monarchy is a strong government is, that it is an intelligible government. The mass of mankind understand it, and they hardly anywhere in the world understand any other. – Walter Bagehot
