Why is the postwar period of French economic growth called the trente glorieuses?

The term trente glorieuses, which translates to "thirty years of glory," refers to the extended period of unprecedented economic growth that France experienced following World War II until the mid-1970s.1

This era was characterized by rapid industrial expansion and significant improvements in living standards for the French population. Several factors contributed to this prosperity:12

• Strategic Planning: The recovery was bolstered by the implementation of national plans, such as those guided by Jean Monnet’s Planning Commissariat, which helped direct development strategies.31
• International Support: Massive aid from the United States played a crucial role in the nation's painful convalescence from the ravages of war.3
• Economic Performance: Between 1960 and 1973 alone, the gross domestic product (GDP) grew at an average rate of nearly 6 percent annually.1

This period of glory eventually moderated following the oil crises of the 1970s, which led to increased unemployment and a shift in economic focus.1
