East and West Berliners came together in celebration. The fall of the Berlin Wall was the first step towards German reunification. The political, economic and social impact of the fall of the Berlin Wall further weakened the already unstable East German government. Germany reunited on 3 October 1990, 11 months after the fall of the Berlin Wall.
