I think not Councillor, unless you count Transylvania as part of Hungary. ((1.7mil at the beginning of the game.)) The precise figure doesn't matter much - a unified Romanian state would be enormous, simply put.In case you've forgotten, Hungary was more than two million people as well, before Slovakia anyways, yet you were opposed to the creation of Slovakia. ((I think they are anyways, if not something close to that.))
Also note that my fears of what an autonomous slovak state would bring were more than justified, as the recent Hungarian secession proved.
