Thanks to a thread in Chat, I just discovered a proposal to make Prince Henry of Prussia the king of the US. This idea was proposed by President Nathaniel Gorham but the offer to him was revoked before he could make a response. Your challenge, if you choose to accept it, is to have this man be the King of America. Any POD is acceptable (I really want this to occur). I'd say at the very least, we'd need George Washington dead soon after the ARW ends.
