- Beginning of the construction of the Berlin Wall in 1961
type: anniversary location: Germany (Berlin)
After the Second World War, as a result of the policy adopted by the Great Powers, Germany was divided into two states. Berlin was also divided into the spheres of influence of the victorious states. The authorities of East Germany, failing to deal adequately with the wave of migration heading for the western part of the country, decided to curtail this unwelcome phenomenon by building a wall. It is estimated that in the period 1949–1961 around 2.6 million people left East Germany. In 1961 the authorities of East Germany began to implement a carefully guarded plan to build a wall. Later this wall came to function as a symbol of a divided Europe.
