East Germany

East Germany (, ), officially known as the German Democratic Republic (GDR; , , DDR), was a country in Central Europe from its formation on 7 October 1949 until its reunification with West Germany on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a socialist "workers' and peasants' state". The economy of this country was centrally planned and state-owned. Although the GDR had to pay substantial war reparations to the Soviets, it became the most successful economy in the Eastern Bloc.

Before its establishment, the country's territory was administered and occupied by Soviet forces with the autonomy of the native communists following the Berlin Declaration abolishing German sovereignty in World War II. The Potsdam Agreement established the Soviet-occupied zone, bounded on the east by the Oder–Neisse line. It was a satellite state of the Soviet Union. The GDR was dominated by the Socialist Unity Party of Germany (SED), a communist party, from 1949 to 1989, before being democratized and liberalized under the impact of the Revolutions of 1989 against the communist states, facilitating East Germany's unification with the West. Unlike West Germany, the SED did not see its state as the successor of the German Reich (1871–1945) and abolished the goal of unification in the constitution (1974). The SED-ruled GDR was often described as a Soviet satellite state; historians described it as an authoritarian regime.

Geographically, the GDR bordered the Baltic Sea to the north, Poland to the east, Czechoslovakia to the southeast, and West Germany to the southwest and west. Internally, the GDR also bordered the Soviet sector of Allied-occupied Berlin, known as East Berlin, which was also administered as the country's ''de facto'' capital. It also bordered the three sectors occupied by the United States, United Kingdom, and France known collectively as West Berlin (de facto part of the FRG). Emigration to the West was a significant problem as many emigrants were well-educated young people; such emigration weakened the state economically. In response, the GDR government fortified its inner German border and later built the Berlin Wall in 1961. Many people attempting to flee were killed by border guards or booby traps such as landmines.

In 1989, numerous social, economic, and political forces in the GDR and abroad, one of the most notable being peaceful protests starting in the city of Leipzig, led to the fall of the Berlin Wall and the establishment of a government committed to liberalization. The following year, a free and fair election was held in the country, and international negotiations between four occupation Allied countries and two German countries led to the signing of the Final Settlement treaty to replace the Potsdam Agreement on the status and border of future-reunited Germany. The GDR ceased to exist when its five states ("Länder") joined the Federal Republic of Germany under Article 23 of the Basic Law, and its East Berlin was also united with West Berlin into a single city of the FRG, on 3 October 1990. Several of the GDR's leaders, notably its last communist leader Egon Krenz, were later prosecuted for offenses committed during the GDR's times. Provided by Wikipedia
