L4. Cold War and Decolonisation
Cold War
• The Cold War (1947-89)
• Why? US and Soviets had been allies in WW2
• Consolidation of Stalinist regimes in Eastern Europe
• Soviet Union occupies large parts of Europe following WW2, which the US
hoped would be organised democratically, but this did not happen and
created the Eastern Bloc
• Soviet support for communist insurgencies in Greece and Turkey
• Britain was supposed to be in control of Greece and Turkey and believed
that the Soviet Union was behind communist insurgencies there
• Suspicion due to different political ideologies (capitalism vs communism)
• Truman Doctrine (12 March 1947)
• The imposition of totalitarian regimes on "free peoples, by direct or indirect aggression,
undermine[s] the foundations of international peace and hence the security of the United
States". The USA would support "free peoples" who were resisting "subjugation by
armed minorities or by outside pressures"
Harry S. Truman, 'Special Message to the Congress on Greece and Turkey:
the Truman Doctrine', 12 Mar. 1947, Public Papers of the Presidents, 1947,
p.178
