The GDR stated it was constructed as an "antifascist protection mechanism" in order to keep out external threats and keep the east Berliners safe in their "Socialist Paradise" but in reality it was to keep people in since many were trying to emigrate out of the communist zone and the GDR would fall because of emigration.
The eastern area of Germany that was held by the Soviets became the so-called German Democratic Republic (RDA), and the other three formed a single area, which was the Federal Republic of Germany (FRG).
In the following years, the western zone began to prosper while the Soviet side suffered economic problems. This, caused millions of Berliners who lived under the communist regime to migrate to West Berlin.
It is for this reason that the authorities of the GDR decided to build a provisional wall that divided the city in two.
