It is one of the greatest symbols of the Cold War. Faced with waves of emigration from East to West, the communist authorities of the German Democratic Republic (1949-1990) decided to react. On the night of August 12 to 13, 1961, the East German government installed fences and barbed wire surrounding West Berlin. This is the beginning of the process of building the wall in Berlin, a border which will gradually be enlarged and consolidated.
The lives of an entire population are being turned upside down: thousands of Berliners are losing their jobs, in the East and West, and thousands of families are also being separated. Finally, on the night of November 9, 1989, Berliners peacefully forced the opening of the crossing points between East and West Berlin and put an end to nearly three decades of divisions in their city.
