George III most likely had porphyria, a liver disease that causes a massive amount of problems in the entire body, also affects the brain and nervous system... They called him "Mad King George" for a reason, he was often quite literally in a state of insanity.
I mean, he handled the American situation terribly, the colonists tried to stay loyal for as long as possible, but he wouldn't reply to their petitions (leading to the list of "Abuses and Usurpation" in the Declaration).
But by all accounts he was in an absolutely terrible state physically and mentally, so some of the blame falls on his ministers.
The Brits actually did mostly appreciate the Hanoverian kings, because they were protestants, they were fertile (so no succession issues), and they let the British parliament run things mostly as they wanted. They had had enough of meddling Catholic kings by 1688.
Fun fact: The last British monarch to be personally on a battlefield was George II (son of George I), who was present at the Battle of Dettingen in Germany in the 1740's.
The Dettingen battle honour is still flown on the regimental colors of the main royal British regiments (Blues and Royals, The Life Guards, and a few others)

Franco had that rank in Spain, and in modern Spain it's reserved for the King.
People who founded it have roots in Falun Gong, a Chinese traditionalist revival / spiritual movement that draws on Buddhism, Confucianism etc.
The CCP cracked down hard on them in the 90's in China, so many are exiled abroad.
And by "cracked down hard" I mean:
