Joachim von Ribbentrop (1893–1946) was Foreign Minister of Germany (1938–1945). He played the key role in negotiating the German-Soviet nonaggression pact that made possible the German invasion of Poland in September 1939. He also directed diplomatic efforts to persuade Germany's Axis partners to deport their Jews to German killing centers and to abandon their Jewish citizens living in Germany to the deportations.
At the International Military Tribunal, Ribbentrop was found guilty on all four counts (conspiracy, crimes against peace, war crimes, and crimes against humanity). He was sentenced to death and was hanged on October 16, 1946.
