One consequence was that families that had been separated could meet each other again. This was because after the construction of the Berlin Wall in 1961 the East and West of Berlin were separated by the wall and it was dangerous to attempt to cross it illegally. This caused families to be split up across the wall. The fall of the wall in 1989 reunited families and allowed them to cross over to the other side of the city. A second consequence was that the fall of the Berlin Wall led to the fall of communist regimes in countries such as Czechoslovakia in December 1989. Soviet control was weakening and uprisings began across Eastern European countries controlled by the USSR. Due to this the fall of the wall became a symbol of the fall of Soviet control across Eastern Europe.
