Emperor Hadrian, I think.

Civil rights pioneer, Irish nationalist/British traitor (depending on who’s side you were on), and (from his own diaries) apparently a very promiscuous gay man.

Grandson of Queen Victoria, older brother of George (who became King George V). He died young so never became king. Allegations that he was the real “Jack the Ripper” have since been completely disproved but the rumours that he was gay persist.
