This is amazing! I... would not have thought crowning TWO monarchs would be a good solution to this. At all. I am not surprised at all there was a lot of political infighting!

if Nicholas II stopped at, say, two or three daughters and never had a hemophilic son, maybe the monarchy would not become so off-kilter

Wait, what did this have to do with the monarchy becoming off-kilter? Is it because of Rasputin?
