The Berlin Wall (German: Berliner Mauer) was a concrete barrier erected by the German Democratic Republic (GDR) (East Germany) that completely encircled the city of West Berlin, separating it from East Germany, including East Berlin. The Wall included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses.
The separate and much longer inner German Border (the IGB) demarcated the border between East and West Germany. Both borders came to symbolize the Iron Curtain between Western Europe and the Eastern Bloc.
Prior to the Wall's erection, 3.5 million East Germans had avoided Eastern Bloc emigration restrictions and escaped into West Germany, many over the border between East and West Berlin. During its existence from 1961 to 1989, the Wall stopped almost all such emigration and separated the GDR from West Berlin for more than a quarter of a century. After its erection, around 5,000 people attempted to escape over the wall, with estimates of the resulting death toll varying between around 100 and 200.
During a revolutionary wave sweeping across the Eastern Bloc, the East German government announced on November 9, 1989, after several weeks of civil unrest, that all GDR citizens could visit West Germany and West Berlin. Crowds of East Germans climbed onto and crossed the wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, parts of the wall were chipped away by a euphoric public and by souvenir hunters; industrial equipment was later used to remove almost all of the rest. The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on October 3, 1990.
