King George VI of the United Kingdom of Great Britain and Northern Ireland and (the last) Emperor of India.
He was a decent man, well loved by his people (especially compared to his reprobate elder brother Edward VIII) for his role in WW2, and one of the few people on this thread to voluntarily give up the title, and the Empire, upon the granting of Independence to India and Pakistan…
Given that I am generally not keen on Empires, giving yours up seems to me to be a sound basis for some praise.
