Greek, Russian, Byzantine, Eastern Orthodox and some Ottoman culture had the main influences on the region in Eastern Europe. Eastern Europe is the eastern part of the continent of Europe. There is no universal list of countries and territories involved due to lack of consensus on its borders. It often includes countries in Europe that were either part of or under the influence of the former Soviet Union.

These include Russia, Ukraine, Belarus, Poland, Bulgaria, Czech Republic, Slovakia, Estonia, Latvia, Lithuania, Hungary, and Moldova. Some sources include the fragmentation of Albania and the former Yugoslavia - Serbia, Macedonia, Slovenia, Croatia, Bosnia. In almost all definitions the Ural ranges, the Ural River and the Caucus region are considered the easternmost limits of Eastern Europe.
