The purpose of the Yalta Conference was to settle the question of what Europe, especially, would look like after the end of World War II. The major decisions made there, in my opinion, were 1) that the USSR would join the war against Japan and 2) that the US would pretty much let the USSR have Eastern Europe for its own.
The reason for this deal was that the US felt that it needed the help of the USSR to defeat Japan. The USSR wanted a buffer zone in Eastern Europe. So the deal was made where they got their buffer and the US got (eventually) Russian help against Japan.
Yalta Conference refers to discussions that took place between President Franklin D. Roosevelt of the United States, Prime Minister Winston Churchill of Great Britain, and Premier Joseph Stalin of the Soviet Union from February 4 to 11, 1945.
The agreement reached during in Yalta Conference included the Following.
- A broad structure of a world peacekeeping organization which later resulted in formation of United Nations Organisation.
- Decision to reestablish order in Europe and to help the defeated countries create democratic governments.
- Division of Germany into four zones to be occupied by Great Britain, the United States, the Soviet Union, and France.
- To support extension of Soviet Union's territory into Poland and hold free elections in Poland under a Soviet-backed government,
- To force Germany to give the Soviet Union equipment and other resources to compensate for Soviet losses.
- Soviet Union to enter the war against Japan in exchange for control of the Kuril Islands, the southern half of Sakhalin Island, and two strategic ports.
