Eastern Europe is the eastern region of Europe. Originally, it meant the countries that were under the influence of the Eastern Orthodox Church in Constantinople during the Middle Ages and Western Europe meant those countries following Catholicism or Protestantism. Later, during the Cold War, it meant the European countries that were allied to the Soviet Union. It is now used to talk about the European post-Soviet states and the former Warsaw Pact. Others say that Eastern Europe is a region of mainly Slavic cultures, though other ethnic groups live there as well. Eastern Europe has a large Roma gypsy population.

According to the widest contemporary definitions - including those used by the UN Statistics Division, several other UN organizations and EuroVoc (the multilingual thesaurus of the EU) - the following states are in Eastern Europe:

1.  Belarus
2.  Bulgaria
3.  Czech Republic
4.  Hungary
5.  Moldova
6.  Poland
7.  Romania
8.  Russia
9.  Slovakia
10.  Ukraine

Partly recognized:

1.  Abkhazia (part of Western Asia)
2.  Kosovo
3.  Transnistria
4.  South Ossetia (part of Western Asia)

Since January 1993 some groups have changed their definitions of Eastern Europe. Although the list above is still the most popular and widely accepted definition of this region, some experts divide the region further into subsections. According to such theories: the Czech Republic, Hungary, Poland and Slovakia are in Central Europe (the western sections of Belarus and Ukraine are also sometimes listed as Central European) or East-Central Europe. Finally, the countries of Serbia, Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Macedonia, Moldova, Montenegro, Romania and Slovenia are occasionally grouped with a number of other countries into Southern Europe, but more often referred to as Southeast (or Southeastern) Europe.
