The Tehran Conference was held in November 1943. Tehran is located in today`s Iran. At the time of the Tehran Conference, World War II was still raging and hopes for an Allied victory were low. Therefore, the majority of the talks at the Tehran Conference focused on how the Second World War would be won. The alliance between the United Kingdom, the United States and the Soviet Union had initially operated by correspondence and a series of bilateral conferences. As the war progressed, however, it was planned to bring together the heads of government of these three Allied powers to discuss key issues arising from the conflict. List the agreements reached by the parties attending the Tehran conference, and Stalin was reluctant to leave Moscow and did not want to risk air travel, while Roosevelt was physically disabled and found travel difficult. Churchill was an avid traveler and had already met Roosevelt five times in North America and twice in Africa as part of an ongoing series of lectures on the war, and had already held two meetings with Stalin in Moscow.  To organize this meeting if necessary, Roosevelt tried to persuade Stalin to go to Cairo. Stalin rejected this offer and also offered to meet in Baghdad or Basra, and finally agreed to meet in Tehran in November 1943.  On December 1, 1943, the three leaders met, made statements, and negotiated the following military conclusions at the conference. This was reinforced by the theatrical culmination of the Tehran Conference, Churchill`s presentation of the Stalingrad sword to Stalin on the second day of the trial. This magnificent ceremonial longsword, specially made by order of the British monarch, bore the inscription “To the steel citizens of Stalingrad, the gift of King George VI, as a sign of the tribute of the British people”.
Although Stalin accepted the above agreements, he dominated the conference and used the prestige of the Soviet victory at the Battle of Kursk to impose his will. Roosevelt tried to cope with Stalin`s onslaught of demands, but there was little he could do but appease him. Churchill advocated the invasion of Italy in 1943, and then Overlord in 1944, on the grounds that Overlord in 1943 was physically impossible and that it would be unthinkable to do something bigger until it could be launched. The conference was to be convened on 2.m 8 November 1943 at 4 p..m. Stalin arrived early, followed by Roosevelt, who pulled out his wheelchair from his dwelling next to the hall. Roosevelt, who had traveled 7,000 miles (11,000 km) and whose health was already deteriorating, met Stalin for the first time. Churchill, walking with his staff from their nearby quarters, arrived half an hour later. Roosevelt and Stalin spent much of the conference convincing Churchill to engage in an invasion of France. which was finally successful on November 30, when Roosevelt announced over lunch that they would launch the invasion in May 1944.  This pleased Stalin, who had urged his allies to open a new front in the West in order to reduce the pressure on his troops. This decision is perhaps the most critical that emerges from this conference, since the desired effect of the relief of Soviet troops was achieved, leading to a Soviet rally and an advance towards Germany, a flood that Hitler could not stop. Other offensives were also discussed to complement the conduct of Operation Overlord, including the possible Allied invasion of southern France prior to the Normandy landings with the aim of moving German forces away from the northern beaches, and even a possible attack on the northern tip of the Adriatic to bypass the Alps and head towards Vienna.
Both plans were based on Allied divisions fighting the German army in Italy at the time of the conference.  Churchill, Stalin and Roosevelt had also agreed at this conference to create the UN according to the principles developed at the Moscow conference. This conference would bring together experts. Iran was then occupied by Soviet and British forces. Shah Mohammad Reza Pahlavi, 22, had only the power of protocol. Iran`s leaders were briefed on the conference a few days earlier. If Stalin and Churchill paid him a courtesy visit, Reza would meet Shah Roosevelt at the USSR embassy, where he had agreed to stay. The Reza Shah was not even invited to the ceremonies that took place in the embassies.
The conference was scheduled to arrive early on November 28, 1943 at 4 a.m. .m Stalin, followed by Roosevelt, who took out his wheelchair from his accommodation next to the venue. Roosevelt, who had traveled 7,000 miles (11,000 km) to participate and whose health was already deteriorating, met Stalin for the first time. Churchill, who had left their nearby home with his colleagues, arrived half an hour later. At the end of the conference, on December 1, 1943, the three leaders communicated the following military conclusions: List of agreements of the parties participating in the Tehran Conference The conference was to meet on November 28, 1943 at 16 p.m.m. The declaration of the three leaders at the end of the conference of December 1, 1943 contained the following military conclusions: In the field of military strategy, Stalin had in this case considerably consolidated his reputation as “master of the battlefield.” General Sir Alan Brooke, who attended the conference as Chief of the Imperial General Staff, later declared his opinion that Stalin “had a military brain of the highest caliber” and surpassed Roosevelt and Churchill in this regard (elsewhere he also commented that the Soviet leader had an “unpleasantly cold face, intelligent and dead, and every time I look at him, I can imagine him sending people to their loss without ever turning a hair”). .
