Berlin (bɜːrˈlɪn , bɛʁˈliːn) is the capital and largest city of Germany by both area and population. Its more than 3.85 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the most populous urban area in Germany.
Stalinist architecture, mostly known in the former Eastern Bloc as Stalinist style (Сталинский стиль) or Socialist Classicism, is the architecture of the Soviet Union under the leadership of Joseph Stalin, between 1933 (when Boris Iofan's draft for the Palace of the Soviets was officially approved) and 1955 (when Nikita Khrushchev condemned "excesses" of the past decades and disbanded the Soviet Academy of Architecture). Stalinist architecture is associated with the Socialist realism school of art and architecture.
The 'Battle of Berlin, designated as the Berlin Strategic Offensive Operation by the Soviet Union, and also known as the Fall of Berlin', was one of the last major offensives of the European theatre of World War II. After the Vistula–Oder offensive of January–February 1945, the Red Army had temporarily halted on a line east of Berlin. On 9 March, Germany established its defence plan for the city with Operation Clausewitz. The first defensive preparations at the outskirts of Berlin were made on 20 March, under the newly appointed commander of Army Group Vistula, General Gotthard Heinrici.
The Berlin Blockade (24 June 1948 – 12 May 1949) was one of the first major international crises of the Cold War. During the multinational occupation of post–World War II Germany, the Soviet Union blocked the Western Allies' railway, road, and canal access to the sectors of Berlin under Western control. The Soviets offered to drop the blockade if the Western Allies withdrew the newly introduced Deutsche Mark from West Berlin.
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility.
