Prince George, Duke of Kent was well known for his relationship with Noel Coward and there have been many gay Kings over the past.
It is interesting that you would cite Prince George, Duke of Kent. He had a number of gay relationships, but he still had a beautiful wife and three children. For the last six years of his life, he was the third highest adult in line to the throne. Since it was the war, there was some concern that a bomb might actually knock out several people in the line of succession at once. There are some conspiracy theorist that feel his death was not accidental; especially given the numerous mysterious circumstances surrounding the plane accident.
Interestingly enough his sister in law, the Queen Mother, maintained a relationship with Noel Coward for the rest of his life. Supposedly she was very tolerant of homosexual men, keeping several in her employ.
Although people get upset with me for saying this, it has always seemed that British society has been much more tolerant of gay men in the arts and in high society for a long time; much more than American society. I mean John Gielgud was caught soliciting gay sex in public restrooms in the 1950's, shortly after he was knighted. He got a standing ovation as a show of support when he returned to the theater. At the same time Liberace was suing newspapers in the USA for calling him
fruity.
That said, it is still a long way from accepting gay artists or local politicians to accepting a gay head of state. I realize that Iceland has a gay head of state, but it is a very small community. I also think there is less resistance to gay women as gay men. I am afraid that if William declared himself to be gay, that there would be strong requests for him to abdicate in favor of his brother. I think he would still have a dukedome, but I don't think he could be accepted as
head of state.
