Fall of the Berlin Wall
The Berlin Wall fell on 9 November 1989 when East Berlin transit restrictions collapsed. Harald Jäger opened the Bornholmer Straße crossing without orders. Crowds poured through. Mauerspechte began chipping away at the Wall that same night. Official dismantling began on 13 June 1990. This event helped trigger the fall of the inner German border, the Malta Summit’s Cold War declaration in early December 1989, and German reunification on 3 October 1990. It was one event in a series that started communism’s fall across Central and Eastern Europe. The source gives two times for Jäger’s decision but no reason for it. It names no other actors, documents no policy change, and does not specify how the Wall’s fall caused wider political change.
