What you have to do
You have to look at Case Studies 1-3 and consider whether there is any evidence that suggests that there was already a Cold War going on in the period 1919-39.

First of all, let's clear up what we mean by the Cold War.

There were two main sides:

• The USA and its allies (including Britain of course)
  
• The USSR and its allies.
  

Most historians say it started soon after the end of World War 2 in 1945

The Cold War (from the late 1940s onwards) was not a 'normal' war like World War 2. Here are four key features of the Cold War:

• A complete lack of trust between politicians on each side
  
• Building up huge armed forces to threaten the other side (but not actually using them)
  
• Using the media to criticise the actions of the other side
  
• Co-operating with and supporting anyone who was an enemy of the other side
  

How to work
1 Work through each of the case studies and analyse the documents in each one. Use the questions on each document to help you.
2 At the end of each case study, complete the relevant section of the Case Study Worksheet.
3 However, you won't be able to make your final conclusion until you have looked at the rest of the Galleries in this Exhibition. So keep this sheet and your other work safe!

Writing it up
When you have worked through the Case Studies and completed the Case Study Worksheets:

Choose 3 pieces of evidence from the Case Studies which could be used to argue that the Cold War did begin in the period 1919-39.

For each piece of evidence:

• Provide full details of its date, author, which Case Study it came from, etc.
  
• Explain how a historian could use it to argue that there was a Cold War already going on in the period 1919-39.
  
• Explain why you think it is a strong piece of evidence.
  
• You might want to use the following framework to record your answers.
