Germany (1990–present)

German reunification (German: Deutsche Wiedervereinigung), also known as the expansion of the Federal Republic of Germany (BRD), was the process of re-establishing Germany as a single sovereign state, which began on 9 November 1989 and culminated on 3 October 1990 with the dissolution of the German Democratic Republic and the integration of its re-established constituent federated states into the Federal Republic of Germany to form present-day Germany. This date was chosen as the customary German Unity Day, and has thereafter been celebrated each year as a national holiday.[1] On the same date, East and West Berlin were also reunified into a single city, which eventually became the capital of Germany.

The East German government, controlled by the Socialist Unity Party of Germany (SED), started to falter on 2 May 1989, when the removal of Hungary's border fence with Austria opened a hole in the Iron Curtain. The border was still closely guarded, but the Pan-European Picnic and the indecisive reaction of the rulers of the Eastern Bloc started off an irreversible movement.[2][3] It allowed an exodus of thousands of East Germans fleeing to West Germany via Hungary. The Peaceful Revolution, part of the international revolutions of 1989 including a series of protests by East German citizens, led to the fall of the Berlin Wall on 9 November 1989 and the GDR's first free elections on 18 March 1990, and then to negotiations between the two countries that culminated in a Unification Treaty.[1] Other negotiations between the two Germanies and the four occupying powers in Germany produced the Treaty on the Final Settlement with Respect to Germany, which granted on 15 March 1991 full sovereignty to a reunified German state, whose two parts had previously been bound by a number of limitations stemming from their post-World War II status as occupation zones, though it was not until 31 August 1994 that the last Russian occupation troops left Germany.

After the end of World War II in Europe, the old German Reich, consequent on the unconditional surrender of all German armed forces and the total absence of any German central government authority, had effectively ceased to exist, and Germany was occupied and divided by the four Allied countries. There was no peace treaty. Two countries emerged. The American-occupied, British-occupied, and French-occupied zones combined to form the FRG, i.e., West Germany, on 23 May 1949. The Soviet-occupied zone formed the GDR, i.e., East Germany, in October 1949. The West German state joined NATO in 1955. In 1990, a range of opinions continued to be maintained over whether a reunited Germany could be said to represent "Germany as a whole"[b] for this purpose. In the context of the revolutions of 1989; on 12 September 1990, under the Two Plus Four Treaty with the four Allies, both East and West Germany committed to the principle that their joint pre-1990 boundary constituted the entire territory that could be claimed by a government of Germany.

The reunited state is not a successor state, but an enlarged continuation of the 1949–1990 West German state. The enlarged Federal Republic of Germany retained the West German seats in the governing bodies of the European Economic Community (EEC) (later the European Union) and in international organizations including the North Atlantic Treaty Organization (NATO) and the United Nations (UN), while relinquishing membership in the Warsaw Pact (WP) and other international organizations to which only East Germany belonged.

Naming

The term "German reunification" was given to the process of the German Democratic Republic joining the Federal Republic of Germany with full German sovereignty from the four Allied-occupied countries to distinguish it from the process of unification of most of the German states into the German Empire (German Reich) led by the Kingdom of Prussia that took place from 18 August 1866 to 18 January 1871, 3 October 1990 was the day when Germany again became a single nation-state. However, for political and diplomatic reasons, West German politicians carefully avoided the term "reunification" during the runup to what Germans frequently refer to as Die Wende (roughly: "the turning point"). The 1990 treaty defines the official term as Deutsche Einheit ("German unity");[1] this is commonly used in Germany.

After 1990, the term die Wende became more common. The term generally refers to the events (mostly in Eastern Europe) that led up to the actual reunification, and loosely translates to "the turning point". Anti-communist activists from Eastern Germany rejected the term Wende as it had been introduced by the SED Secretary General Egon Krenz.[4]

Some people have stated that the reunification can be classified as an annexation of the GDR by the FRG.[5][6][7][8][9][10][11] Scholar Ned Richardson-Little from the University of Erfurt noted that the terminology of an annexation can be interpreted from backgrounds across the political spectrum.[12] In 2015, a Russian proposal was made that classified it as an annexation. Mikhail Gorbachev named the proposal 'nonsense'.[13][14] In 2010, Matthias Platzeck referred to the reunification as an 'anschluss'.[15]

After the suicide of Adolf Hitler on 30 April 1945, Karl Dönitz assumed the title of Reichspräsident in accordance with Hitler's last political testament. As such, he authorised the signing of the unconditional surrender of all German armed forces, which took effect on 8 May 1945. He tried to establish a government under Ludwig Graf Schwerin von Krosigk in Flensburg. This government, however, was not recognised by the Allies; and Dönitz and all its other members were arrested on 23 May by British forces. On 5 June 1945, in Berlin, the supreme commanders of the four occupying powers signed a common Berlin Declaration, which formally confirmed the defeat of Nazi Germany in World War II, as well as the complete legal extinction of the German Reich with the death of Adolf Hitler on 30 April 1945[16] Germany was occupied by four countries representing the victorious Allies signing the agreement (US, UK, France, and the USSR). The declaration also formed the Allied Control Council (ACC) of these four countries ruling Germany,[17][18] and confirmed the German borders which had been in force before the annexation of Austria. With the Potsdam Agreement at the Potsdam Conference between the three main Allies defeating the European Axis (US, UK, and the USSR) on 2 August 1945, Germany was divided by the Allies into occupation zones, each under the military government of one of these four countries. The agreement also modified Germany's border, with the country de facto losing its former territories east of the Oder–Neisse line to Poland and the Soviet Union (most for Poland because the eastern territories of former Poland were annexed by the USSR). Germany's border decision came under pressure[clarification needed] from Stalin, the dictator of the Soviet Union. During and after the war, many ethnic Germans who had lived in the historically German lands in Central and Eastern Europe, including territories east of the Oder–Neisse line, fled and were expelled to post-war German and Austrian territory. Saarland, an area in the French occupation zone, was separated from Germany when its own constitution took effect, to become a French protectorate on 17 December 1947.[19]

Developments from 1948

Among the Allies, geo-political tension between the Soviet Union and Western Allies in occupied Germany as part of their tension in the world led the Soviets to de facto withdraw from the ACC on 20 March 1948 (four occupying countries restored the act of the ACC in 1971) and blockade West Berlin (after the introduction of a new currency in West Germany on 20 June of the same year) from 20 June 1948 to 12 May 1949, but the USSR could not force the three Western Allies to withdraw from West Berlin as they wanted; consequently, the foundation of a new German state became impossible. The Federal Republic of Germany, or "West Germany", a liberal democracy, was established in the US, UK, and French zones on 23 May 1949. West Germany was de jure established in the Trizone occupied by three Western Allies and established on 1 August 1948. Its forerunner was the Bizone formed by the US and UK zones on 1 January 1947 before the inclusion of the French zone.[20][21][22] The Trizone did not include West Berlin, which was also occupied by three Western Allies, although the city was de facto part of the West German state; the German Democratic Republic or "East Germany", a communist state with a planned and public economy which declared itself as the new state and the successor of the German Reich,[23] a legal-former German state (in contrast to the Federal Republic of Germany, which considered itself a state partially identical with the German Reich and not merely its successor, with the "partial identity" limited to apply only within its current de facto territory[24]), was established in the Soviet zone on 7 October 1949. It de jure did not include East Berlin, occupied by the Soviets, although the city was de facto its capital: the severe ideological conflict between German politicians and sociologists in their self-governing east–west society was preceded by the influence of higher[clarification needed] foreign occupiers; however this only really rose to become official with the birth of the two countries of Germany in the context of the period of international tension during the Cold War. The capital of West Germany was Bonn; however it was only considered provisional due to the West German aspiration to establish Berlin as its capital, although at the time Berlin was divided, with the eastern part de facto managed by East Germany. East Germany originally also wanted to gain West Berlin and make the unified Berlin its capital.

1952 onwards

The Western Allies and West Germany rejected the Soviet Union's idea of neutral reunification in 1952, resulting in the two German governments continuing to exist side-by-side. Most of the border between two Germanies, and later the border in Berlin, were physically fortified and tightly controlled by East Germany from 1952 and 1961, respectively. The flags of the two German countries were originally the same, but in 1959 East Germany changed its flag.[25] The West German government initially did not recognize the new and de facto German–Polish border, nor East Germany, but later eventually recognized the border in 1972 (with the 1970 Treaty of Warsaw[26][27][28]) and East Germany in 1973 (with the 1972 Basic Treaty[29]) when applying a common policy to reconcile with the communist countries in the East. The East German government also had encouraged two-state status after initially denying the existence of the West German state, influenced by the Soviet policy of "peaceful coexistence". The mutual recognition of the two Germanies paved the way for both countries to be widely recognized internationally.[c] The two Germanies joined the United Nations as two separate country members in 1973 and East Germany abandoned its goal of reunification with their compatriots in the West in a constitutional amendment the following year.

Mikhail Gorbachev had led the country as General Secretary of the Communist Party of the Soviet Union since 1985. During this time, the Soviet Union experienced a period of economic and political stagnation, and correspondingly decreased intervention in Eastern Bloc politics. In 1987, the United States President Ronald Reagan gave a famous speech at the Brandenburg Gate, challenging Soviet General Secretary Mikhail Gorbachev to "tear down this wall" which prevented freedom of movement in Berlin. The wall had stood as an icon for the political and economic division between East and West, a division that Churchill had referred to as the "Iron Curtain". Gorbachev announced in 1988 that the Soviet Union would abandon the Brezhnev Doctrine and allow the Eastern European countries to freely determine their own internal affairs.[31] In early 1989, under a new era of Soviet policies of glasnost (openness) and perestroika (economic restructuring), and taken further by Gorbachev, the Solidarity movement took hold in Poland. Further inspired by other images of brave defiance, a wave of revolutions swept throughout the Eastern Bloc that year. In May 1989, Hungary removed their border fence. However, the dismantling of the old Hungarian border facilities did not open the borders nor were the previous strict controls removed, and the isolation by the Iron Curtain was still intact over its entire length. The opening of a border gate between Austria and Hungary at the Pan-European Picnic on 19 August 1989 then set in motion a peaceful chain reaction, at the end of which there was no longer a GDR and the Eastern Bloc had disintegrated.[3][2] Extensive advertising for the planned picnic was made by posters and flyers among the GDR holidaymakers in Hungary. The Austrian branch of the Paneuropean Union, which was then headed by Karl von Habsburg, distributed thousands of brochures inviting them to a picnic near the border at Sopron. It was the largest escape movement from East Germany since the Berlin Wall had been built in 1961. After the picnic, which was based on an idea of Karl's father Otto von Habsburg to test the reaction of the USSR and Mikhail Gorbachev to an opening of the border, tens of thousands of media-informed East Germans set off for Hungary.[32] The media reaction of Erich Honecker in the "Daily Mirror" of 19 August 1989 showed the public in East and West that the Eastern European communist rulers had suffered a loss of power in their own sphere, and that they were no longer in control of events: "Habsburg distributed leaflets far into Poland, in which the East German holidaymakers were invited to a picnic. When they came to the picnic, they were given gifts, food and Deutsche Marks, and then they were persuaded to come to the West." In particular, Habsburg and the Hungarian Minister of State Imre Pozsgay considered whether Moscow would command the Soviet troops stationed in Hungary to intervene.[33] But, with the mass exodus at the Pan-European Picnic, the subsequent hesitant behavior of the Socialist Unity Party of East Germany and the nonintervention of the Soviet Union broke the dams. Thus, the bracket[clarification needed] of the Eastern Bloc was broken.[34]

Hungary was no longer ready to keep its borders completely closed or to oblige its border troops to use force of arms. By the end of September 1989, more than 30,000 East German citizens had escaped to the West before the GDR denied travel to Hungary, leaving Czechoslovakia as the only neighboring state to which East Germans could escape.[35][36]

Even then, many people within and outside Germany still believed that real reunification between the two countries would not happen in the foreseeable future.[37] The turning point in Germany, called Die Wende, was marked by the "Peaceful Revolution" leading to the fall of the Berlin Wall on the night of 9 November 1989, with East and West Germany subsequently entering into negotiations toward eliminating the division that had been imposed upon Germans more than four decades earlier.
