Tehran,Yalta and Potsdam Conference

Explanation:

Conferences of Tehran,Yalta and Potsdam

Yalta was the second of three major wartime conferences among the Big Three. It was preceded by the Tehran Conference in November 1943, and was followed by the Potsdam Conference in July 1945.

Were they all productive :

Tehran Conference -By the end of 1943 as the war situation improved, the Big Three started to look forward to the prospects for peace.After the war Russia was promised compensation in Poland, whilst Poland would gain some German territory, and all the leaders agreed on the idea of a new world peace organisation to replace the League of Nations.

Yalta Conference - At the time (still during the war), Yalta was thought to be a great success.The Yalta Conference helped lead to the Cold War by giving the Soviet Union control over Eastern Europe. At the conference, the Soviet Union was given the right to control Eastern Europe.

Potsdam Conference -The conference failed to settle most of the important issues at hand and thus helped set the stage for the Cold War that would begin shortly after World War II came to an end. The meeting at Potsdam was the third conference between the leaders of the Big Three nations.
