I understand that a lot of that comes from plundering other nations world wide, taxes for war effort, etc etc, but is that all? How exactly did they make money? Do they get a portion of the country's taxes annually?
There's definitely more to be said about the "plundering other nations" aspect, but to tide you over, I've previously answered In Regency England, where does a gentleman's income come from, and how does he store and access it?
