Input: Context: The Eastern Bloc was the group of communist states of Central and Eastern Europe, generally the Soviet Union and the countries of the Warsaw Pact. The terms Communist Bloc and Soviet Bloc were also used to denote groupings of states aligned with the Soviet Union, although these terms might include states outside Central and Eastern Europe., The Socialist Unity Party of Germany, established in April 1946, was the governing MarxistLeninist political party of the German Democratic Republic from the country's foundation in October 1949 until it was dissolved after the Peaceful Revolution in 1989., West Berlin was a city that existed in the period between the end of the Berlin Blockade on 12 May 1949 to German reunification on 3 October 1990 as a political enclave surrounded by East Berlin and East Germany. It was east of the Inner German border and only accessible by land from West Germany by narrow rail and highway corridors. It consisted of the American, British, and French occupation sectors established in 1945 and shared economic, political, legal, and sporting systems with West Germany, but was not "de jure" part of it. It had a special and unique legal status because its administration was formally conducted by the Western Allies. East Berlin, "de jure" occupied and administered by the Soviet Union, was the "de facto" capital of East Germany. The Berlin Wall, built in 1961, physically divided East and West Berlin until it fell in 1989., East Germany, formally the German Democratic Republic or GDR, was an Eastern Bloc state during the Cold War period. From 1949 to 1990, it administered the region of Germany that was occupied by Soviet forces at the end of World War IIthe Soviet Occupation Zone of the Potsdam Agreement, bounded on the east by the OderNeisse line. The Soviet zone surrounded West Berlin, but did not include it; as a result, West Berlin remained outside the jurisdiction of the GDR.
The German Democratic Republic was established in the Soviet Zone, while the Federal Republic was established in the three western zones. East Germany was a satellite state of the Soviet Union. Soviet occupation authorities began transferring administrative responsibility to German communist leaders in 1948, and the GDR began to function as a state on 7 October 1949. Soviet forces, however, remained in the country throughout the Cold War. Until 1989, the GDR was governed by the Socialist Unity Party (SED), though other parties nominally participated in its alliance organisation, the National Front of Democratic Germany. , The Peaceful Revolution was the process of sociopolitical change that led to the end of the Socialist Unity Party of Germany dominance of the German Democratic Republic (GDR or East Germany) and the transition to a parliamentary democracy which enabled the reunification of Germany. This turning point was wholly created through the violence-free initiatives, protests, and successful demonstrations, which decisively occurred between the local elections held in May 1989 and the GDR's first free parliamentary election in March 1990., The People's Chamber (German: Volkskammer) was the unicameral legislature of the German Democratic Republic (East Germany). From its founding in 1949 until the first free elections on 18 March 1990, all members of the "Volkskammer" were elected via a list controlled by the Socialist Unity Party of Germany (SED), called the National Front. Despite the appearance of a multi-party system, all these Bloc parties were completely subservient to the SED. In addition, seats were also allocated to various mass organizations affiliated with the SED, such as the Free German Youth., The OderNeisse line is the international border between Germany and Poland. It was drawn at the Potsdam Conference in the aftermath of the Second World War and is primarily delineated along the Oder and Lusatian Neisse rivers in Central Europe, meeting the Baltic Sea to the north, just west of the Polish seaports of Szczecin and winoujcie (German: "Stettin" and "Swinemünde"). All prewar German territory east of the line and within the 1937 German boundaries (23.8% of the former Weimar Republic) were placed under International Law Administrative status, with most of it being made part of newly-Communist Poland. The small remainder, consisting of the territory surrounding the German city of Königsberg (now renamed Kaliningrad, in honour of Soviet head of state Mikhail Kalinin) in northern East Prussia, was allocated to the Soviet Union (as Kaliningrad Oblast of the Russian SFSR, today the Russian Federation) after the war (pending the final World War II peace treaty for Germany). The vast majority of the native German population in these territories fled, or was killed or expelled by force. The OderNeisse line marked the border between the German Democratic Republic (East Germany) and Poland from 1950 to 1990. East Germany confirmed the border with Poland in 1950, while West Germany, after a period of refusal, finally accepted the border (with reservations) in 1970. In 1990 the newly reunified Germany and the Republic of Poland signed a treaty recognizing it as their border., The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991. A union of multiple subnational republics, its government and economy were highly centralized. The Soviet Union was a one-party federation, governed by the Communist Party with Moscow as its capital., The National Front of the German Democratic Republic ( German : Nationale Front der Deutschen Demokratischen Republik , NF ) until 1973 the National Front of Democratic Germany German : Nationale Front des Demokratischen Deutschlands ) was an alliance ( Popular Front ) of political parties and mass organisations in East Germany ( also known as a Blockpartei ) . The NF was controlled by the Socialist Unity Party of Germany and was formed to stand in elections to the East German parliament , the Volkskammer ( `` People 's Chamber '' ) ., Potsdam is the capital and largest city of the German federal state of Brandenburg. It directly borders the German capital Berlin and is part of the Berlin/Brandenburg Metropolitan Region. It is situated on the River Havel, southwest of Berlin's city center., World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history., The Potsdam Agreement was the agreement between three of the Allies of World War II, United Kingdom, United States, Union of Soviet Socialist Republics, for the military occupation and reconstruction of Germanyreferring to the German Reich with its pre-war 1937 borders including the former eastern territoriesand the entire European theatre of War territory. It also included Germany's demilitarisation, reparations and the prosecution of war criminals., The Free German Youth, also known as the FDJ, is a socialist youth movement in Germany. Formerly it was the official youth movement of the German Democratic Republic (GDR) and the Socialist Unity Party of Germany., The Oder (Czech, Lower Sorbian and , Upper Sorbian: "Wódra") is a river in Central Europe. It rises in the Czech Republic and flows (generally north- and northwest-ward) through western Poland, later forming of the border between Poland and Germany, part of the OderNeisse line. The river ultimately flows into the Szczecin Lagoon north of Szczecin and then into three branches (the Dziwna, wina and Peene) that empty into the Gulf of Pomerania of the Baltic Sea., The Soviet Occupation Zone ("Sovetskaya okkupatsionnaya zona Germanii", "Soviet Occupation Zone of Germany") was the area of central Germany occupied by the Soviet Union from 1945 on, at the end of World War II. On 7 October 1949 the German Democratic Republic (GDR), which became commonly referred to as East Germany, was established in the Soviet Occupation Zone., Subject: national front , Relation: headquarters_location, Options: (A) alliance (B) berlin (C) central (D) east berlin (E) germany (F) global (G) hiroshima (H) kaliningrad (I) moscow (J) poland (K) potsdam (L) united kingdom (M) warsaw
