Work as Foreign Minister
Following the rise of Adolf Hitler in Germany, Joachim became the Nazis foreign minister to other countries in Europe, most notably toward the United Kingdom and the Soviet Union. His son Rudolf von Ribbentrop was a SS Captain (Hauptsturmführer) while his SS rank was Obergruppenführer (Lieutenant General). Joachim was known for being openly against much of Hitler's military plans (except of invading Poland), the most notable was the declaration of war against the Soviet Union.
Despite his disagreements with Hitler and other SS members, Joachim played a major role in planning The Holocaust. Since he was the Foreign Minister for the Nazis, he worked with many loyal nations that supported the Nazi government in deporting Jews and other "inferior people" to the death camps in the majority of Europe.
Trail and execution
After being captured by the Allies after the fall of Nazi Germany, he was put on trial with many Nazi leaders at Nuremberg. Joachim was found guilty and sentenced to death.
Joachim von Ribbentrop was the first of the Nazis at Nuremberg to be executed (the first one Hermann Goring had already committed suicide) on October 16th, 1946. His last words were "God protect Germany. God have mercy on my soul. My final wish is that Germany should recover her unity and that, for the sake of peace, there should be understanding between East and West. I wish peace to the world." Nuremberg Prison Commandant Burton C. Andrus later recalled that, immediately before the hood was placed over his head, Ribbentrop turned to the prison's Lutheran chaplain and whispered, "I'll see you again."
