      The Truman Doctrine and the Marshall Plan

      Lesson details

      Learning outcome

      I can explain the significance of the Truman Doctrine and the Marshall Plan.

      Key learning points

      1. Truman was concerned that high levels of poverty would allow communism to spread more easily in post-war Europe.
      2. The Truman Doctrine committed the USA to a policy of containment.
      3. The aim of the Marshall Plan was to stop the spread of communism by providing economic support to Western Europe.
      4. In response to the Marshall Plan, Stalin established Cominform and Comecon.
      5. The Truman Doctrine and Marshall Plan (and the Soviet response they provoked) widened the divide between East and West.

      Keywords

      • Truman Doctrine - Truman's idea that it was the USA's responsibility to prevent the spread of communism around the world

      • Containment - using American influence and military resources to prevent the spread of communism into non-communist countries

      • Isolationism - an approach to international relations that is based on not getting involved in the affairs of other countries

      • Marshall Plan - an American programme of economic aid that aimed to stop the spread of communism by supporting countries to recover from the Second World War

      Common misconception

      The USA always considered it had a responsibility to protect Europe from threats.

      Before the Second World War, the USA had a policy of isolationism which meant not getting involved in the affairs of other countries.

      Teacher tip

      Encourage students to keep adding to a glossary of names and acronyms (such as Comecon and Cominform) as they go through this unit, and try to use them accurately in their work.
