Why didn't we keep King George then?
King George was not interested in shaping the people,. He was interested in taxing them to finance world domination.
................
And world domination has a lot to do with changing the society in the dominion.
King George was self aggrandizing , as almost any king would be , that is typical of the specie.
King George also had duty as leader of his church to promote Christ within his dominion, and after the revival that swept England ,he co-operated with the Parliament ,set his Navy and Army to eradication of Slavery in the empire and suppressing the slave trade at sea.
The Parliament was a lot more democratic than the monarch , this part of history is interesting for having both a powerful monarch and a democratic institution with a lot of power in remarkable co-existence.
But not far away in France was this Voltaire fellow living with a ridiculously intrusive and powerful monarch writing that people need to think for themselves. This took a while to influence the situation.
