In February 1945, the leaders of the UK, America and the Soviet Union met in Yalta in the Crimean region of the Soviet Union. After winning World War Two, these powers became known as the Big Three. They met to discuss what would happen in Europe after Nazi Germany was defeated.
Joseph Stalin (Soviet Union), Franklin Roosevelt (USA) and Winston Churchill (UK) decided that Germany would be split into four zones. The Soviet Union, USA, UK and France would each control a zone. The German capital Berlin, which was in the Soviet zone, would also be divided into four.
