GENERAL KNOWLEDGE

Detailed explanation-1: -The Berlin Wall was built by the German Democratic Republic during the Cold War to prevent its population from escaping Soviet-controlled East Berlin to West Berlin, which was controlled by the major Western Allies. It divided the city of Berlin into two physically and ideologically contrasting zones.

Detailed explanation-2: -The Berlin Wall was not one wall, but two. Measuring 155 kilometres (96 miles) long and four metres (13 feet) tall, these walls were separated by a heavily guarded, mined corridor of land known as the ‘death strip’.

Detailed explanation-3: -On the night of August 12-13, 1961, East German soldiers laid down more than 30 miles of barbed wire barrier through the heart of Berlin. East Berlin citizens were forbidden to pass into West Berlin, and the number of checkpoints in which Westerners could cross the border was drastically reduced.

Detailed explanation-4: -The Soviet Union occupied East Germany and installed a rigidly controlled communist state. The other three Allies shared the occupation of West Germany and helped rebuild the country as a capitalist democracy. The City of Berlin, located 200 miles inside East Germany, was also divided.
