I know Romania has only been independent since the late 19th Century. But in the Middle Ages, Wallachia, Moldavia, and of course Transylvania were considered Romanian Principalities/states. And Wallachia brings the reason for mentioning Romania. Vlad the Impaler. The bloodthirsty ruthless tyrant that inspired the legend of Dracula. In a series that features Attila the Hun, Alexander, and Isabella, it's only natural to include Vlad into that club. So far most of the European Civs seem to have a Middle Ages type theme. What says Middle Ages more than Vlad Dracula to lead Romania?
