Leaders discussion of the USSR, USA and Great Britain about the place and time of the trilateral meeting in 1943

The article is devoted to the study of the process of preparation of the Tehran conference of leaders of the USSR, USA and Great Britain, held in the Iranian capital from November 28 to December 1, 1943. Based on the analysis of the trilateral correspondence of I.V. Stalin, F.D. Roosevelt and W. Churchill, the authors determine the objectives of the meeting and indicate the positions of the parties regarding the time and place of its holding. It is proved that each of the leaders wanted to organize a conference on the territory under their control, but the desire to resolve controversial issues prevailed over political ambitions, which was a decisive factor in rallying the allies of World War II to fight the aggressors. The novelty of the study is due to the lack of study in the domestic historiography of the organizational aspect of the Tehran conference, which in turn is extremely important for an objective understanding of how the conditions favorable for the adoption of crucial military and political decisions of the time and the development of initial projects of the post-war world order were achieved.
