Die Mauer Steht

In 1972, the Basic Treaty (German: Grundlagenvertrag) was negotiated between the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany). The two German counties each other as sovereign states for the first time, an abandonment of West Germany's Hallstein Doctrine in favor of the Ostpolitik championed by West German Chancellor Willy Brandt. On April 27th, 1972 West German opposition leader Rainer Barzel called for a constructive vote of no confidence against Brandt's government. Had the motion carried, Barzel would have succeeded Brandt as Chancellor

The final tally received 247 votes, two short of the necessary 249 were needed to expel Brandt from office.

In Die Mauer Steht, Barzel succeeds in becoming Chancellor and dooming Ostpolitik for the rest of the century, further dividing the two Germanies and changing the course of history.
