Since 1914, the French state has faced a succession of daunting and at times almost insurmountable crises. The turbulent decades from 1914 to 1969 witnessed near-defeat in 1914, economic and political crisis in 1926, radical political polarization in the 1930s, military conquest in 1940, the deep division of France during the Nazi Occupation, political reconstruction after 1944, de-colonization (with threatening civil war provoked by the Algerian crisis), and dramatic postwar modernization. However, this tumultuous period was not marked just by crises but also by tremendous change. Economic, social and political "modernization" transformed France in the twentieth century, restoring its confidence and its influence as a leader in global economic and political affairs. This combination of crises and renewal has received surprisingly little attention in recent years. The present collection show-cases significant new scholarship, reflecting greater access to French archival sources, and focuses on the role of crises in fostering modernization in areas covering politics, economics, women, diplomacy and war.
