Eastern Europe is the name of the region which encompasses the countries in the east of Europe. The region is not strictly defined, as some of these countries fall into more than one area, e.g. Transylvania being part of Romania is considered a part of Central Europe, while the rest of the country is in Eastern Europe.
Common region names
Most of the countries in Eastern Europe share a common recent history being the republics of former Soviet Union (with the exception of Bulgaria and Romania).
Eastern Europe is sometimes confused with the Eastern Bloc, which is a Cold War name for communist countries that were behind the "iron curtain". Eastern Bloc included all the countries of Eastern Europe, several countries of Central Europe and individual countries on other continents, particularly in Asia.
