He was kidnapped on 5 September 1977 by the far left Red Army Faction ("Rote Armee Fraktion", RAF) and subsequently murdered; his driver and police escort of three policemen were also murdered when his car was ambushed. The German government determined that it was in the national interest not to negotiate with terrorists. The abduction and murder are commonly seen as the climax of the RAF campaign in 1977, known as the German Autumn. After his death Schleyer has been extensively honoured in Germany; the Hanns Martin Schleyer Prize, the Hanns Martin Schleyer Foundation and the Hanns-Martin-Schleyer-Halle are named in his honour. In 2017 German President Frank-Walter Steinmeier and the German government marked the 40th anniversary of the kidnapping.
