Key concepts in Post-war western and northern Europe (1945–2000)

Key Idea: Western and northern Europe after 1945: the wartime allies split, Germany was divided, and western Europe rebuilt fast. Later, Spain moved from dictatorship to democracy and Germany reunited.

Cold War and recovery, 1945 to 1963

  • Mistrust at Yalta and Potsdam led to the Truman Doctrine (1947).
  • Germany: four zones, the Berlin Airlift (1948 to 1949), two states in 1949, the Wall in 1961.
  • Marshall Plan (1948 to 1952): $13 billion, on condition that Europe cooperated.
  • Adenauer's social market economy and de Gaulle's Fifth Republic (1958); France's Trente Glorieuses.
