The Cold War emerged from deteriorating relations between the Allied powers after World War II, marked by ideological conflicts between causes of the Cold War 1943-46 including capitalism and communism. Key diplomatic meetings at Tehran, agreements at Yalta Conference 1945, and growing tensions at Potsdam Conference 1945 shaped the post-war world order.
Key points:
- The Grand Alliance between USA, USSR, and Britain fractured due to competing political ideologies
- Three pivotal conferences (Tehran, Yalta, Potsdam) attempted to establish post-war arrangements
- Growing mistrust evidenced by secret communications like Long and Novikov telegrams
- Introduction of Truman Doctrine and Marshall Plan formalized America's anti-communist stance
- Division of Germany and Berlin became a major point of contention
