The origins of the Cold War
This podcast aims to look at three key areas – why the alliance between the USA and the USSR broke down in 1945, how Stalin take control of eastern Europe in 1945 and America’s reaction to it, and the consequences of the Berlin Blockade.
The podcast opens with a short explanation of the deteriorating relationship between the USA and the USSR through the Second World War. It goes on to present an overview of the two major Allied conferences – Yalta and Potsdam – and outlines the key agreements and disagreements that emerged from them.
Opening with an extract from Churchill’s famous Iron Curtain speech, the second part of this episode explores the way in which Stalin extended Soviet control over eastern Europe to establish a ‘buffer zone’ of communist states around the USSR. It then goes on to detail the USA’s response in terms of the Truman Doctrine and the Marshall Plan. Examples are given of each.
The third section of the podcast focuses on the Berlin Blockade of 1948-9. It begins with the background of the divided Germany after the Second World War. An explanation is then given of how Berlin became further divided between the communist and non-communist zones leading to Stalin launching the Berlin Blockade. The Allied ‘air lift’ is then described.
The episode finishes with some exam tips on how to answer a question about who was to blame for the Cold War in a balanced way.
