Central Europe is the region lying between the variously and vaguely defined areas of Eastern and Western Europe. In addition, Northern, Southern and Southeastern Europe may variously delimit or overlap into Central Europe. The term has come back into fashion since the end of the Cold War, which had divided Europe politically into East and West, with the Iron Curtain splitting "Central Europe" in half. With exception for a kernel from Poland to Hungary, the understanding of the concept varies considerably from nation to nation, but also from time to time.

The region is usually used to mean:

Poland   

Czech Republic

 Slovakia

 Austria

 Hungary

Central Europe behind the Iron Curtain

Following World War II, large parts of Europe that were culturally and historically Western became part of the Eastern bloc, which effectively neutralized the concept of Central Europe. Following the dissolution of the Warsaw Pact and the end of the Cold War, this distinction has again come into use, often to cover those countries that had been Warsaw Pact members but are now members of NATO and the European Union.

During the Cold War, the English term Central Europe was increasingly applied only to the westernmost former Warsaw Pact countries (Poland to Hungary) to specify them as communist states that were culturally tied to Western Europe. This usage continued after the end of the Warsaw Pact when these countries started to undergo transition.

In everyday usage, this is the most common meaning of Central Europe, not least among Central Europeans who wish to distance themselves from "Eastern Europe".

Although Slovenia as a part of Yugoslavia was strictly speaking not a member of the Warsaw Pact, Slovenia's 20th century history has much in common with that of the other Central European countries. East Germany, on the other hand, was from 1949–1990 a loyal member of the Warsaw Pact, but would now rather be seen as the inheritor of Protestant Prussian culture than of Catholic Central Europe.

The new members of the European Union

After the enlargement of the European Union of 1 May 2004, the term Central Europe is sometimes incorrectly used in a way that means "the new members of EU"— from Estonia to Malta— perhaps in particular by writers who want to avoid the term coined by Donald Rumsfeld, New Europe, which may be perceived to carry too much American ignorance of European matters. Malta and Cyprus, as well as Estonia and Latvia, are sometimes now also included, but as these new members of the EU are clearly more differentiated from most of the western EU members economically it is arguably an inaccurate construction in its own right. It can be also questioned what there is that unites the nations of a region so constructed apart from a less advanced economy. A usage that closer adheres to the common cultural traits, and also the shared experience of post-war Stalinist rule, may be less prone to cause confusion.
