Drang nach Osten ( [ˈdʁaŋ nax ˈʔɔstn̩], "yearning for the East", "thrust toward the East", "push eastward", "drive toward the East" or "desire to push East") was a term coined in the 19th century to designate German expansion into Slavic lands. The term became a motto of the German nationalist movement in the late nineteenth century. In some historical discourses, "Drang nach Osten" combines historical German settlement in Central and Eastern Europe, medieval (12th-13th centuries) military expeditions like the ones of the Teutonic Knights (see Northern Crusades), and Germanisation policies and warfare of Modern Age German states like the Nazi Lebensraum concept. In Poland, the term "Drang nach Osten" was used in discourse when describing Germanization of Poland while on the German side the slogan was part of a wider nationalist discourse approving the medieval settlement in the east and the idea of the "superiority of German culture". The slogan Drang nach Westen ("thrust toward the West") derived from "Drang nach Osten" was used to depict an alleged Polish drive westward. It was one of the core elements of German nationalism and part of Nazi ideology; as Adolf Hitler said on 7 February 1945: It is eastwards, only and always eastwards, that the veins of our race must expand. It is the direction which Nature herself has decreed for the expansion of the German peoples.
The first known use of "Drang nach Osten" was by the Polish journalist Julian Klaczko in 1849, yet it is debatable whether he invented the term as he used it in form of a citation. Because the term is used almost exclusively in its German form in English, Polish, Russian, Czech and other languages, it has been concluded that the term is of German origin.
Drang nach Osten is connected with the medieval German Ostsiedlung. This "east colonization" referred to the expansion of German culture, language, states, and settlement into eastern and Northern European regions inhabited by Slavs and Balts.
Population growth during the High Middle Ages stimulated movement of peoples from the Rhenish, Flemish, and Saxon territories of the Holy Roman Empire eastwards into the less-populated Baltic region and Poland. These movements were supported by the German nobility, the Slavic kings and dukes, and the medieval Church. The majority of this settlement took place at the expense of Polabian Slavs and pagan Balts (see Northern Crusades).
The future state of Prussia, named for the conquered Old Prussians, had its roots largely in these movements. As the Middle Ages came to a close, the Teutonic Knights, who had been invited to northern Poland by Konrad of Masovia, had assimilated and forcibly converted much of the southern Baltic coastlands.
After the Partitions of Poland by the Kingdom of Prussia, Austria, and the Russian Empire in the late 18th century, Prussia gained much of western Poland. The Prussians, and later the Germans, engaged in a policy of Germanization in Polish territories. Russia and Sweden eventually conquered the lands taken by the Teutonic Knights in Estonia and Livonia.
The term became a centerpiece of the program of the German nationalist movement in 1891, with the founding of the Alldeutschen Verbandes, in the words: „Der alte Drang nach dem Osten soll wiederbelebt werden" ("The old Drang nach Osten must be revived"). Nazi Germany employed the slogan in calling the Czechs a "Slav bulwark against the Drang nach Osten" in the 1938 Sudeten crisis.
Despite Drang nach Osten policies, population movement took place in the opposite direction also, as people from rural low-developed areas in the East were attracted by the prospering industrial areas of Western Germany. This phenomenon became known by the German term Ostflucht, literally the flight from the East.
A new Drang nach Osten was called for by German nationalists to oppose a Polish Drang nach Westen ("thrust toward the West"). World War I had ended with the Treaty of Versailles, by which most or parts of the Imperial German provinces of Posen, West Prussia, and Upper Silesia were given to reconstituted Poland; the West Prussian city of Danzig became the Free City of Danzig. The Polish paper Wprost used both "Drang nach Osten" and "Drang nach Westen" in August 2002 to title stories about German RWE company taking over Polish STOEN and Polish migration into eastern Germany, respectively.
"Drang nach Westen" is also the ironic title of a chapter in Eric Joseph Goldberg's book Struggle for Empire, used to point out the "missing" eastward ambitions of Louis the German who instead expanded his kingdom to the West.
With the development of romantic nationalism in the 19th century, Polish and Russian intellectuals began referring to the German Ostsiedlung as Drang nach Osten. The German Empire and Austria-Hungary attempted to expand their power eastward; Germany by gaining influence in the declining Ottoman Empire (the Eastern Question) and Austria-Hungary through the acquisition of territory in the Balkans (such as Bosnia and Herzegovina).
Adolf Hitler, dictator of Nazi Germany from 1933–1945, called for a Drang nach Osten to acquire territory for German colonists at the expense of central and eastern European nations (Lebensraum). The term by then had gained enough currency to appear in foreign newspapers without explanation. His eastern campaigns during World War II were initially successful with the conquests of Poland, the Baltic countries, Belarus, Ukraine and much of European Russia by the Wehrmacht; Generalplan Ost was designed to eliminate the native Slavic peoples from these lands and replace them with Germans. The Wehrbauer, or soldier-peasants, would settle in a fortified line to prevent civilization arising beyond and threatening Germany.
This was greatly hindered by the lack of German people who actually desired to settle in the east, let alone act as Teutonic Knights there. Settlements actually established during the war did not receive colonists from the Altreich, but in the main part East European Germans resettled from Soviet "spheres of interest" according to the Molotov-Ribbentrop Pact, and such Poles as deemed Germanizable by Nazis. However, the Soviet Union began to reverse the German conquests by 1943, and Nazi Germany was defeated by the Allies in 1945.
Most of the demographic and cultural outcome of the Ostsiedlung was terminated after World War II. The expulsion of Germans after World War II east of the Oder-Neisse line in 1945-48 on the basis of decisions of the Potsdam Conference were later justified by their beneficiaries as a rollback of the Drang nach Osten. "Historical Eastern Germany", which historically was the land of the Baltic people called Old Prussians who had been colonised and assimilated by German Drang Nach Osten, was split between Poland, Russia, and Lithuania (a Baltic country) and repopulated with settlers of the respective ethnicities. The Oder-Neisse line has been gradually accepted to be the eastern German boundary by all post-war German states (East and West Germany as well as reunited Germany), dropping all plans of (re-)expansion into or (re-)settlement of territories beyond this line. The Old Prussians were conquered by the Teutonic Knights in the 13th century, and gradually assimilated over the following centuries; the Old Prussian language was extinct by the 17th or early 18th century. Henry Cord Meyer, in his book "Drang nach Osten: Fortunes of a Slogan-Concept in German-Slavic Relations, 1849-1990" claims that the the slogan "Drang nach Osten" originated in the Slavic world, and it also was more widely used than in Germany
