Introduction Europe is not really a continent that should be defined as a large landmass divided from the rest of the continents by water. This has led to many geographers identifying a Eurasian Continent. But since modern geographers came up with modern Europe, the European geographers came up with their own definition of the European continent ( Barnard, 111 ). The Eastern Boundary has been controversial since the formation of the European continent. Most geographers have portrayed the European continent to extend up to the Ural Mountains in Russia. This was a result of the Ural Mountains being the first natural barrier to the East. There has been a talk of European Russia, a part of Russia that is highly modernized and heavily populated which lies west of the Ural Mountains of Russia. This has also led to terms like ‘Central Europe’ for countries lying between European Russia and Western Europe ( Meunier, 114 ). Concerning the European Realm, geographers have put the eastern boundary to the Russian border. Greenland, the largest island in the world is also included. This is because of its historical ties to Europe particularly Denmark. The geographers have connected the Eastern European countries to the Russian Realm. This is because they are communists and had historical, political, and economic ties with the Soviet Union during the cold war era. However, geography authors chose to put Eastern Europe back to Europe predicting that the country’s political and economic interactions will tend to be towards the European rather than towards the Russian ( Sullivan, 1160 ). Boundaries of Europe In physical geography, Europe is well defined by the waters in the north, south, and west. It is important to note that the eastern boundary has no physical barrier. This lack of physical barrier in the eastern bounder has played an important historical role. Napoleon of France and Hitler of Germany easily traveled armies across the plain to attack Russia. This explains the Russian desire to have buffer states under its control lying between Europe and Russian ( Barnard, 124 ). There is also the cultural boundary bordering Europe. This is defined by language, religion, and ethnicity. Looking at the maps of language and it is easy to understand why some geographers put Russia and Europe into one realm ( Guéguen, 400 ). In the Economic boundaries, many of the Eastern European countries are adjusting their economies to the global economy and leaning towards the European economy. The economic boundaries give many reasons why there should exist a European realm and a different Russian realm. However, some of the maps still indicate that Eastern European countries should be included in the Russian realm ( Meunier, 115 ). The historical, the main issue concerning the European realm is the Eastern boundary. The countries of Eastern Europe were a member of the cold war era Warsaw Pact. They are countries that signed the Warsaw pact in Warsaw in Poland that signed a treaty of friendship and mutual alliance in 1956. Russia also signed the Warsaw pact ( Steiner, 132 ).
