1918-1944

The European idea at the beginning of the 20th century

The treaties signed after the First World War redrew the map of Europe, sealing the fate of three empires (the German, the Austro-Hungarian and the Ottoman) and bringing new states into being (including Czechoslovakia, Hungary and Yugoslavia). The frustrations born out of this realignment made reconciliation among the peoples of Europe a difficult matter. Nevertheless, a political rapprochement emerged in the 1920s, symbolised by the Aristide Briand's policy toward the Germany of Gustav Stresemann, which resulted in the Franco-German Pact of Locarno. But the economic crisis of the 1930s exacerbated nationalistic feelings and the spirit of revenge. From 1933 onwards, Nazi Germany unleashed repeated coups de force, heralding a new war. The horrors of this second global conflict were at the root of the plans for European unification put into effect after 1945.
