Tehran
In the Russia Embassy in Iran, the Tehran Conference was held. The Tehran Conference (codenamed Eureka) was the meeting of Joseph Stalin, Franklin D. Roosevelt and Winston Churchill between November 28 and December 1, 1943. Most of it was held at the Soviet Embassy in Tehran, Iran. It was the first World War II conference amongst the Big Three (the Soviet Union, the United States, and the United Kingdom) where Stalin was present. The aim of the Tehran conference was to plan the final strategy for the war against Nazi Germany and its allies. The discussion was mostly about the opening of a second front in Western Europe.
