The event took place on December 7, 1970, in Warsaw, Poland, during a visit to a monument to the German occupation-era Warsaw Ghetto Uprising. After laying a wreath, Brandt unexpectedly, and apparently spontaneously, knelt. He remained silently in that position for a short time, surrounded by a large group of dignitaries and press photographers. Brandt had actively resisted the early Nazi regime, and had spent most of the time of Hitler's reign in exile. The occasion of Brandt's visit to Poland at the time was the signing of the Treaty of Warsaw between West Germany and Poland, guaranteeing German acceptance of the new borders of Poland. The treaty was one of the Brandt-initiated policy steps to ease tensions between West and East during the Cold War.
On the same day, Brandt signed the Treaty of Warsaw, which acknowledged the Oder–Neisse line as the final German border with Poland. Both actions attracted controversy within Germany, as did Ostpolitik in general, which was supported by only a narrow majority of the people and had opposition within Brandt's own party. Its voters had included a significant proportion of expellees from the formerly-German territories in Poland, most of whom left to support the conservative parties. According to a Der Spiegel survey of the time, 48% of all West Germans thought the Kniefall was excessive, 41% said it was appropriate and 11% had no opinion. The Kniefall was a symbolic actionthe opposition tried to use against Brandt, as in a constructive vote of no confidence in April 1972, which Brandt won by only two votes. Brandt's landslide win in the next elections, in late 1972, was also due to the growing view among voters that Brandt's Ostpolitik, symbolized by the Kniefall, and his reformist domestic policies were helping to boost Germany's international reputation and so should be supported. His party won its best federal election result ever.
Internationally
While at the time, positive reactions may have been limited, his show of humility was a small but vital step in bridging the gaps World War II had left between Germany and Eastern Europe. In historical terms, Brandt gained much renown for this act, and it is thought to be one of the reasons he received the Nobel Peace Prize in 1971. A monument to Willy Brandt was unveiled on 6 December 2000, in Willy Brandt Square in Warsaw on the eve of the 30th anniversary of his famous gesture.
Brandt's memories
Brandt was repeatedly interviewed about the genuflection and about his motives. He later noted that: Egon Bahr, an eyewitness and Brandt's friend and political ally of many years, recalled in a 2010 interview: "The only thing he said was, in that moment, as he stood looking at the ribbon, he thought: Just laying the wreath is not enough."
