"

On 19 March 1970, the East and West German heads of government Willi Stoph and Willy Brandt met in Erfurt, the first such meeting since the division of Germany. During the 1970s and 1980s, as the economic situation in GDR worsened, many old buildings in city centre decayed, while the government fought against the housing shortage by building large Plattenbau settlements in the periphery. The Peaceful Revolution of 1989/1990 led to German reunification.[citation needed]
