The Tehran Conference: November 28 - December 1, 1943
- Written by Editor

The Tehran Conference (codenamed Eureka) was a strategy meeting held between Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill from 28 November to 1 December 1943. It was held in the Soviet Embassy in Tehran, Iran and was the first of the World War II conferences held between all of the "Big Three" Allied leaders (the Soviet Union, the United States, and the United Kingdom). It closely followed the Cairo Conference which had taken place on 22-26 November 1943, and preceded the 1945 Yalta and Potsdam Conferences. Although all three of the leaders present arrived with differing objectives, the main outcome of the Tehran Conference was the commitment to the opening of a second front against Nazi Germany by the Western Allies. The conference also addressed relations between the Allies and Turkey and Iran, operations in Yugoslavia and against Japan as well as the envisaged post-war settlement. A separate protocol signed at the conference pledged the Big Three's recognition of Iran's independence.
Soviet, British and other Commonwealth armed forces invaded Iran during World War II. The invasion lasted from 25 August to 17 September 1941, and was codenamed Operation Countenance. The purpose was to secure Iranian oil fields and ensure Allied supply lines for the Soviets fighting against Axis forces on the Eastern Front. Though Iran was officially neutral, according to the Allies its monarch Rezā Shāh was friendly toward the Axis powers and was deposed during the subsequent occupation and replaced with his young son Mohammad Reza Pahlavi.
(a) Declaration of the Three Powers, December 1, 1943
We the President of the United States, the Prime Minister of Great Britain, and the Premier of the Soviet Union, have met these four days past, in this, the Capital of our Ally, Iran, and have shaped and confirmed our common policy. We express our determination that our nations shall work together in war and in the peace that will follow.
As to war-our military staffs have joined in our round table discussions, and we have concerted our plans for the destruction of the German forces. We have reached complete agreement as to the scope and timing of the operations to be undertaken from the east, west and south. The common understanding which we have here reached guarantees that victory will be ours.
And as to peace-we are sure that our concord will win an enduring Peace. We recognize fully the supreme responsibility resting upon us and all the United Nations to make a peace which will command the goodwill of the overwhelming mass of the peoples of the world and banish the scourge and terror of war for many generations.
With our Diplomatic advisors we have surveyed the problems of the future. We shall seek the cooperation and active participation of all nations, large and small, whose peoples in heart and mind are dedicated, as are our own peoples, to the elimination of tyranny and slavery, oppression and intolerance. We will welcome them, as they may choose to come, into a world family of Democratic Nations.
No power on earth can prevent our destroying the German armies by land, their U Boats by sea, and their war plants from the air. Our attack will be relentless and increasing.Emerging from these cordial conferences we look with confidence to the day when all peoples of the world may live free lives, untouched by tyranny, and according to their varying desires and their own consciences.
We came here with hope and determination. We leave here, friends in fact, in spirit and in purpose.
ROOSEVELT, CHHRCHILL and STALIN Signed at Tehran, December 1, 1943
(b) Declaration of the Three Powers Regarding Iran, December 1, 1943
The President of the United States, the Premier of the U. S. S. R. and the Prime Minister of the United Kingdom, having consulted with each other and with the Prime Minister of Iran, desire to declare the mutual agreement of their three Governments regarding their relations with Iran.
The Governments of the United States, the U. S. S. R., and the United Kingdom recognize the assistance which Iran has given in the prosecution of the war against the common enemy, particularly by facilitating the transportation of supplies from overseas to the Soviet Union.
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.
With respect to the post-war period, the Governments of the United States, the U. S. S. R., and the United Kingdom are in accord with the Government of Iran that any economic problems confronting Iran at the close of hostilities should receive full consideration, along with those of other members of the United Nations, by conferences or international agencies held or created to deal with international economic matters.
The Governments of the United States, the U. S. S. R., and the United Kingdom are at one with the Government of Iran in their desire for the maintenance of the independence, sovereignty and territorial integrity of Iran They count upon the participation of Iran, together with all other peace-loving nations, in the establishment of international peace, security and prosperity after the war, in accordance with the principles of the Atlantic Charter, to which all four Governments have subscribed.

(c) Military Conclusions of the Tehran Conference
The Conference:
Agreed that the Partisans in Yugoslavia should be supported by supplies and equipment to the greatest possible extent, and also by commando operations:
Agreed that, from the military point of view, it was most desirable that Turkey should come into the war on the side of the Allies before the end of the year:
Took note of Marshal Stalin's statement that if Turkey found herself at war with Germany, and as a result Bulgaria declared war on Turkey or attacked her, the Soviet would immediately be at war with Bulgaria. The Conference further took note that this fact could be explicitly stated in the forthcoming negotiations to bring Turkey into the war:
Took note that Operation OVERLORD would be launched during May 1944, in conjunction with an operation against Southern France. The latter operation would be undertaken in as great a strength as availability of landing-craft permitted. The Conference further took note of Marshal Stalin's statement that the Soviet forces would launch an offensive at about the same time with the object of preventing the German forces from transferring from the Eastern to the Western Front:
Agreed that the military staffs of the Three Powers should henceforward keep in close touch with each other in regard to the impending operations in Europe. In particular it was agreed that a cover plan to mystify and mislead the enemy as regards these operations should be concerted between the staffs concerned.
