The German and Soviet foreign ministers were key diplomatic figures during World War II, particularly highlighted by the signing of the Molotov-Ribbentrop Pact in 1939. This non-aggression treaty between Nazi Germany and the Soviet Union included secret protocols dividing Eastern Europe into spheres of influence, which had a profound impact on the political landscape of Europe leading up to and during the war. Their negotiations and actions set the stage for territorial expansions and invasions that shaped the early years of the conflict.
