World War 2 was not over at this time but it was close to the end.

The big three Stalin (Russia), Roosevelt (USA), and Churchill (Britain) agreed on some important matters.

Stalin agreed to enter was against Japan after Germany surrendered.

Germany to be divided into 4 zones and also Berlin (capital) to be divided into 4 zones too. (for Britain, France, Germany and USA).

Hunt down and punish war criminals (found evidence from concentration camps).

Join new United Nations to keep peace.

As countries liberated from German army they could hold free elections.

Eastern Europe should become a Soviet Sphere of Influence (to give Russia more control and security).

Problems at Yalta:

Division of Germany - ¾ Capitalist only ¼ Communist.

Soviet sphere of influence - not properly defined how would Russia interpret this?

Poland - Russia wanted to expand into Poland but Capitalist powers didn't want Russia expanding.
