The first half of the twentieth century brought almost unimaginable violence and destruction, leading historian Eric Hobsbawm to label the era the “age of catastrophe.”9 Shaken by the rapid cultural change and economic collapse that followed the tragedy of World War I, many Europeans embraced the radical politics of communism and fascism. Some found appeal in visions of a classless society or a racially pure national community, and totalitarian dictators like Stalin and Hitler capitalized on these desires for social order, building dictatorial regimes that demanded total allegiance to an ideological vision. Even as these regimes rewarded supporters and promised ordinary people a new age, they violently repressed their enemies, real and imagined. The vision proved fatal: the great clash of ideologies that emerged in the 1920s and 1930s led to history’s most deadly war, killing millions and devastating large swaths of Europe and East Asia.

Only the reluctant Grand Alliance of the liberal United States and Great Britain with the Communist Soviet Union was able to defeat the Axis powers. After 1945 fascism was finished, discredited by total defeat and the postwar revelation of the Holocaust. To make sure, the Allies would occupy the lands of their former enemies. Rebuilding a devastated Europe proved a challenging but in the end manageable task: once recovery took off, the postwar decades brought an economic boom that led to levels of prosperity unimaginable in the interwar years. Maintaining an alliance between the capitalist West and the Communist East was something else. Trust quickly broke down. Europe would be divided into two hostile camps, and Cold War tensions between East and West would dominate European and world politics for the next fifty years.
