Final answer:
The Teheran Conference of 1943 saw important decisions made by the Allied leaders, including an agreement for the Soviet Union to declare war on Japan, the division of postwar Germany into occupied zones, plans for a second front in Europe, the establishment of free elections in Eastern Europe, and preliminary talks of an international organization later known as the United Nations.
Step-by-step explanation:
The wartime Teheran Conference was a historical meeting that took place during World War II from November 28 to December 1, 1943, between the Big Three: Churchill, Roosevelt, and Stalin. They met in Tehran to discuss various aspects of the war, and several important decisions were made.
Primarily, it was agreed that the Soviet Union would declare war on Japan once Germany surrendered. In regards to postwar Germany, it was agreed that it would be divided into separate occupied zones controlled by the U.S., Britain, France, and the Soviet Union. Plans were also made for the opening of a second front in Europe through a cross-channel invasion scheduled for May 1944.
A key decision with far-reaching implications was Stalin's agreement to allow free elections in Eastern European nations occupied by Soviet armies at the end of the war. Furthermore, discussion between Roosevelt and Stalin led to the initial blueprints for what would later become the United Nations, an international organization where the five Big Powers would have veto power.
