Ulrich Friedrich Wilhelm Joachim von Ribbentrop, more commonly known as Joachim von Ribbentrop, was Foreign Minister of Nazi Germany from 1938 until 1945.
Ribbentrop first came to Adolf Hitler's notice as a well-travelled businessman with more knowledge of the outside world than most senior Nazis and as an authority on world affairs. He offered his house for the secret meetings in January 1933 that resulted in Hitler's appointment as Chancellor of Germany. He became a close confidant of Hitler, to the disgust of some party members, who thought him superficial and lacking in talent. He was appointed Ambassador to the Court of St James in 1936 and then Foreign Minister of Germany in February 1938.
Before World War II, he played a key role in brokering the Pact of Steel and the Molotov–Ribbentrop Pact. He favoured retaining good relations with the Soviets, and opposed the invasion of the Soviet Union. After 1941, Ribbentrop's influence declined.
Arrested in June 1945, Ribbentrop was tried at the Nuremberg trials and convicted for his role in starting World War II in Europe and enabling the Holocaust.
