Through Nazi Germany, Soviet Union and Territorial dispute

Following the collapse of the Third Reich in 1945 and its defeat in World War II, Germany was stripped of its territorial gains. Beyond that, more than a quarter of its old pre-war territory was annexed by communist Poland and the Soviet Union. The German populations of these areas were expelled to the west. Saarland was a French protectorate from 1947 to 1956 without the recognition of the "Four Powers", because the Soviet Union opposed it, making it a disputed territory.

At the end of World War II, there were some eight million foreign displaced people in Germany, mainly forced laborers and prisoners. This included around 400,000 survivors of the Nazi concentration camp system, where many times more had died from starvation, harsh conditions, murder, or being worked to death. Between 1944 and 1950, some 12 to 14 million German-speaking refugees and expellees arrived in Western and central Germany from the former eastern territories and other countries in Eastern Europe; an estimated two million of them died on the way there. Some nine million Germans were prisoners of war.

With the beginning of the Cold War, the remaining territory of Germany was divided between the Western Bloc led by the United States, and the Eastern Bloc led by the USSR. Two separate German countries emerged:

Under Chancellor Konrad Adenauer, West Germany built strong relationships with France, the United Kingdom, the United States, and Israel. West Germany also joined the North Atlantic Treaty Organization and the European Economic Community. East Germany's economy, centrally planned in the Soviet style, grew increasingly stagnant; the East German secret police tightly controlled daily life, and the Berlin Wall (1961) ended the steady flow of refugees to the West. The country was reunited on 3 October 1990, following the decline and fall of the SED as the ruling party of East Germany and the Peaceful Revolution there.

Division of Germany

Four military occupied zones

At the Potsdam Conference (17 July to 2 August 1945), after Germany's unconditional surrender on 8 May 1945, the Allies officially divided Germany into the four military occupation zones — France in the southwest, the United Kingdom in the northwest, the United States in the south, and the Soviet Union in the east, bounded on the east by the new Poland-Germany border on the Oder-Neisse line. At Potsdam, these four zones in total were denoted as 'Germany as a whole', and the four Allied Powers exercised the sovereign authority they now claimed over Germany in agreeing 'in principle' to the ceding of territory of the former German Reich east of 'Germany as a whole' to Poland and the Soviet Union.

In addition, under the Allies' Berlin Declaration (1945), the territory of the extinguished German Reich was to be treated as the land area within its borders as of 31 December 1937. All land expansion from 1938 to 1945 was hence treated as automatically invalid, including Eupen-Malmedy, Alsace-Lorraine, Austria, Lower Styria, Upper Carniola, Southern Carinthia, Bohemia, Moravia, Czech Silesia, Danzig, Poland, and Memel.

Flight and expulsion of ethnic Germans

The northern half of East Prussia in the region of Königsberg was administratively assigned by the Potsdam Agreement to the Soviet Union, pending a final Peace Conference (with the commitment of Britain and the United States to support its incorporation into Russia); and was then annexed by the Soviet Union. The Free City of Danzig and the southern half of East Prussia were incorporated into and annexed by Poland; the Allies having assured the Polish government-in-exile of their support for this after the Tehran Conference in 1943. It was also agreed at Potsdam that Poland would receive all German lands East of the Oder-Neisse line, although the exact delimitation of the boundary was left to be resolved at an eventual Peace Conference. Under the wartime alliances of the United Kingdom with the Czechoslovak and Polish governments-in-exile, the British had agreed in July 1942 to support "the General Principle of the transfer to Germany of German minorities in Central and South Eastern Europe after the war in cases where this seems necessary and desirable". In 1944 roughly 12.4 million ethnic Germans were living in territory that became part of post-war Poland and Soviet Union. Approximately 6 million fled or were evacuated before the Red Army occupied the area. Of the remainder, around 2 million died during the war or in its aftermath (1.4 million as military casualties; 600,000 as civilian deaths), 3.6 million were expelled by the Poles, one million declared themselves to be Poles, and 300,000 remained in Poland as Germans. The Sudetenland territories, surrendered to Germany by the Munich Agreement, were returned to Czechoslovakia; these territories containing a further 3 million ethnic Germans. 'Wild' expulsions from Czechoslovakia began immediately after the German surrender.

The Potsdam Conference subsequently sanctioned the "orderly and humane" transfer to Germany of individuals regarded as "ethnic Germans" by authorities in Czechoslovakia, Poland, and Hungary. The Potsdam Agreement recognized that these expulsions were already underway and were putting a burden on authorities in the German Occupation Zones, including the re-defined Soviet Occupation Zone. Most of the Germans who were being expelled were from Czechoslovakia and Poland, which included most of the territory to the east of the Oder-Neisse Line. The Potsdam Declaration stated:

Since the influx of a large number of Germans into Germany would increase the burden already resting on the occupying authorities, they consider that the Allied Control Council in Germany should in the first instance examine the problem with special regard to the question of the equitable distribution of these Germans among the several zones of occupation. They are accordingly instructing their respective representatives on the control council to report to their Governments as soon as possible the extent to which such persons have already entered Germany from Poland, Czechoslovakia, and Hungary, and to submit an estimate of the time and rate at which further transfers could be carried out, having regard to the present situation in Germany. The Czechoslovak Government, the Polish Provisional Government and the control council in Hungary are at the same time being informed of the above and are being requested meanwhile to suspend further expulsions pending the examination by the Governments concerned of the report from their representatives on the control council.

Many of the ethnic Germans, who were primarily women and children, and especially those under the control of Polish and Czechoslovak authorities, were severely mistreated before they were ultimately deported to Germany. Thousands died in forced labor camps such as Lambinowice, Zgoda labour camp, Central Labour Camp Potulice, Central Labour Camp Jaworzno, Glaz, Milecin, Gronowo, and Sikawa. Others starved, died of disease, or froze to death while being expelled in slow and ill-equipped trains; or in transit camps.

Altogether, around 8 million ethnic German refugees and expellees from across Europe eventually settled in West Germany, with a further 3 million in East Germany. In West Germany these represented a major voting block; maintaining a strong culture of grievance and victimhood against Soviet Power, pressing for a continued commitment to full German reunification, claiming compensation, pursuing the right of return to lost property in the East, and opposing any recognition of the postwar extension of Poland and the Soviet Union into former German lands. This block eventually became substantially aligned with the Christian Democratic Union of Germany; although in practice 'westward-looking' CDU policies favouring the Atlantic Alliance and the European Union worked against the possibility of achieving the objectives of the expellee population from the east through negotiation with the Soviet Union. But for Adenauer, fostering and encouraging unrealistic demands and uncompromising expectations amongst the expellees would serve his "Policy of Strength" by which West Germany contrived to inhibit consideration of unification or a final Peace Treaty until the West was strong enough to face the Soviets on equal terms. Consequently, the Federal Republic in the 1950s adopted much of the symbolism of expellee groups; especially in appropriating and subverting the terminology and imagery of the Holocaust; applying this to post-war German experience instead. Eventually in 1990, following the Treaty on the Final Settlement With Respect to Germany, the unified Germany indeed confirmed in treaties with Poland and the Soviet Union that the transfer of sovereignty over the former German eastern territories in 1945 had been permanent and irreversible; Germany now undertaking never again to make territorial claims in respect of these lands.

The intended governing body of Germany was called the Allied Control Council, consisting of the commanders-in-chief in Germany of the United States, the United Kingdom, France and the Soviet Union; who exercised supreme authority in their respective zones, while supposedly acting in concert on questions affecting the whole country. In actuality however, the French consistently blocked any progress towards re-establishing all-German governing institutions; substantially in pursuit of French aspirations for a dismembered Germany, but also as a response to the exclusion of France from the Yalta and Potsdam conferences. Berlin, which lay in the Soviet (eastern) sector, was also divided into four sectors with the Western sectors later becoming West Berlin and the Soviet sector becoming East Berlin.
