There are many events regarding the rise and fall of the Berlin Wall, I will try to explain some of them in my next report. The person responsible for the construction of the Wall was Walter Ulbricht. He was a long-time member of the German Communist Party. After 1958, the German Democratic Republic (GDR or East Germany) entered a new phase of development. As a result, a sharp increase in industrial production was ordered in East Berlin. This was part of a seven-year economic plan aimed at bringing per capita consumption in the GDR to the level of the Federal Republic or Germany (FRG or West Germany). The only major flaw in this project was the opening of the borders to the West. Berlin. Hundreds of East Germans were leaving the country daily. Most of them went underground and were not noticed. Even regular spot checks by police had no effect as most people avoided it by making multiple trips with few belongings at a time. This flow of refugees continued for approximately six months. After that, it stopped for a while, but as soon as the effect of the Seven Year Plan began to be felt, the flow of refugees resumed. In 1959 there were a total of 144,000 refugees and in 1960 it rose to 199.00 and in the first seven months of 1961 it rose again to 207,000. This included hundreds of professionals, 688 doctors, 296 dentists and 2,698 engineers. A total of 2.5 million people fled between 1949 and 1961, even though Berlin was politically divided after the end of World War II. To highlight and stop the flow from East Berlin. It was physically divided by a wall in 1961. Fleeing the republic was now a criminal offense. The people of East Berlin were effectively locked in their country. During the summer of 1961, Ulbricht convinced the Russians that force was the only way to stop the flight of the entire population. Early on Sunday morning, August 13, 1961, the wall was erected. The GDR began to block East Berlin from West Berlin with barbed wire and anti-tank obstacles. Streets were demolished, cobblestone barricades were erected, and tanks were assembled in crucial locations. Subway and local rail services between East and West Berlin were disrupted.
