The Tehran Conference

The Tehran Conference (codenamed EUREKA) was the meeting of Joseph Stalin, Franklin D. Roosevelt and Winston Churchill between November 28 and December 1, 1943 in Tehran, Iran. It was the first World War II conference among the Big Three (the Soviet Union, the United States, and the United Kingdom) in which Stalin was present. The chief discussion was centered on the opening of a second front in Western Europe. At the same time a separate protocol pledged the three countries to recognize Iran's independence:

"The Three Governments realize that the war has caused special economic difficulties for Iran, and they are agreed that they will continue to make available to the Government of Iran such economic assistance as may be possible, having regard to the heavy demands made upon them by their world-wide military operations, and to the world-wide shortage of transport, raw materials, and supplies for civilian consumption." (Declaration of the Three Powers Regarding Iran—December 1, 1943)

Most importantly the conference was organized to plan the final strategy for the war against Nazi Germany and its allies.
