Moldavia

The Principality of Moldavia, not to be confused with the nation state of Moldava, is an historic region in Eastern Europe. Located between the Dniester River and the Eastern Carpathian Mountains, it was an autonomous state until it merged with the nation of Wallachia (Dracula country!) and became part of modern Romania.

On the original 1966-1968 Batman television series, Moldavia still existed and was recognized as a republic. They were even sponsored at the Gotham City World's Fair, though the ceremonial cutting of the "Friendship cake" was interrupted by the explosive exploits of the Riddler.
