settlement in Central and Eastern Europe

Part of the motivation behind the territorial changes is based on historical events in Germany and
Western Europe Western Europe is the western region of Europe. The region's countries and territories vary depending on context. The concept of "the West" appeared in Europe in juxtaposition to "the East" and originally applied to the ancient Mediterranean ...
. Migrations that took place over more than a millennium led to pockets of Germans living throughout Central and Eastern Europe as far east as Russia. The existence of these enclaves was sometimes used by German nationalists, such as the Nazis, to justify territorial claims.


The rise of European nationalism

The territorial changes of Germany after World War II can be interpreted in the context of the evolution of global nationalism and European nationalism. The latter half of the 19th century and the first half of the 20th century saw the rise of
nationalism Nationalism is an idea and movement that holds that the nation should be congruent with the State (polity), state. As a movement, nationalism tends to promote the interests of a particular nation (as in a in-group and out-group, group of peo ...
in Europe. Previously, a country consisted largely of whatever peoples lived on the land that was under the dominion of a particular ruler. As principalities and kingdoms grew through conquest and marriage, a ruler could wind up with many different ethnicities under his dominion. The concept of nationalism was based on the idea of a "people" who shared a common bond through race, religion, language and culture. Furthermore, nationalism asserted that each "people" had a right to its own state. Thus, much of European history in the latter half of the 19th century and the first half of the 20th century can be understood as efforts to realign national boundaries with this concept of "one people, one state". Many interior conflicts were a result of more or less pressurising citizens of alternative ethnicities and/or other native languages to assimilate to the ethnicity dominant in the state. Switzerland was the exception, lacking a common native language. Much conflict would arise when one nation asserted territorial rights to land outside its borders on the basis of an ethnic bond with the people living on the land. Another source of conflict arose when a group of people who constituted a minority in one nation would seek to secede from the nation either to form an independent nation or join another nation with whom they felt stronger ties. Yet another source of conflict was the desire of some nations to expel people from territory within its borders because people did not share a common bond with the majority of people of that nation.

Territorial changes after World War II

As it became evident that the Allies were going to defeat Nazi Germany decisively, the question arose as to how to redraw the borders of Central and Eastern European countries after the war. In the context of those decisions, the problem arose of what to do about ethnic minorities within the redrawn borders. The territorial changes at the end of World War II were part of negotiated agreements between the victorious Allies to redraw national borders and arrange for deportation of all Germans that were east of the Oder–Neisse line. The Allies occupied Germany, but the Western allies and Soviet Union formed separate governments covering specific parts of Germany. On 7 October 1949, the two German countries appeared with the establishment of the German Democratic Republic; however the two German countries were unified to form present-day Germany on 3 October 1990.

The precise location of the border was left open; the western Allies also accepted in general the principle of the Oder River as the future western border of Poland and of population transfer as the way to prevent future border disputes.
