During the summer of 1989, in the face of a growing migration of East Germans to West Germany via Hungary and mass demonstrations, East German authorities unexpectedly eased the border restrictions in November 1989, allowing East German citizens to travel to the West. This led to the acceleration of the process of reforms in East Germany that concluded with German reunification on October 3, 1990. Under the terms of the treaty between West and East Germany, Berlin again became the capital of the reunited Germany. | During the summer of 1989, in the face of a growing migration of East Germans to West Germany via Hungary and mass demonstrations, East German authorities unexpectedly eased the border restrictions in November 1989, allowing East German citizens to travel to the West.
