Neue Ostpolitik (German for "new eastern policy"), or Ostpolitik for short, was the normalization of relations between the Federal Republic of Germany (FRG, or West Germany) and Eastern Europe, particularly the German Democratic Republic (GDR, or East Germany) beginning in 1969. Influenced by Egon Bahr, who proposed "change through rapprochement" in a 1963 speech at the Evangelische Akademie Tutzing, the policies were implemented beginning with Willy Brandt, fourth Chancellor of the FRG from 1969 to 1974.
Ostpolitik was an effort to break with the policies of the Christian Democratic Union (CDU), which was the elected government of West Germany from 1949 until 1969. The Christian Democrats under Konrad Adenauer and his successors tried to combat the Communist regime of East Germany, while Brandt's Social Democrats tried to achieve a certain degree of cooperation with East Germany.
The term Ostpolitik has since been applied to Pope Paul VI's efforts to engage Eastern European countries during the same period. The term Nordpolitik was also coined to describe similar rapprochement policies between North and South Korea beginning in the 1980s.
Following the end of World War II in 1945, Allied-occupied Germany was split into two states: the Federal Republic of Germany (FRG, or West Germany) and the German Democratic Republic (GDR, or East Germany). Initially, both governments claimed that they represented the entire German nation. However, the Federal Republic saw itself as the only German government with democratic legitimacy. Later, at the end of the 1960s, the communist government of the GDR claimed that there was no longer a common German nation as the GDR had established a "socialist" nation.
