Unable to stop the growing civil unrest, Erich Honecker was forced to resign in October, and on 9 November, East German authorities unexpectedly allowed East German citizens to enter West Berlin and West Germany. Hundreds of thousands of people took advantage of the opportunity; new crossing points were opened in the Berlin Wall and along the border with West Germany. This led to the acceleration of the process of reforms in East Germany that ended with the German reunification that came into force on 3 October 1990.
