The American People in the Twentieth Century: A History

Bibliographic Details

Author: David M. Kennedy
Publisher: Oxford University Press
Year: 1999

Thesis Statement

Kennedy argues that the central theme of American history from 1900 to 1945 was the nation’s fraught and transformative journey from a posture of isolationism and provincialism to one of global leadership and international engagement, a shift driven by the twin crucibles of economic catastrophe and total war, which fundamentally reshaped the relationship between the individual citizen and the federal government.

Summary

In this sweeping synthesis, David M. Kennedy, a Pulitzer Prize-winning historian, masterfully charts the course of the United States through the first half of the twentieth century. The narrative begins with a nation confident in its industrial might yet ambivalent about its role beyond its shores, a society marked by profound inequalities and a political system grappling with the challenges of modernization. Kennedy meticulously traces the progressive impulses of the early 1900s, the disillusionment following World War I, and the roaring yet unstable prosperity of the 1920s. The book’s core, however, lies in its profound analysis of the Great Depression and World War II. Kennedy posits that these sequential crises acted as a “great accelerator,” forcing a dramatic redefinition of American citizenship and state power. The New Deal, in his analysis, was not merely a series of programs but a revolution in expectations, establishing a new social contract that promised economic security. This newly empowered federal state was then mobilized with unprecedented scale and efficiency for global war after 1941. Kennedy concludes by examining how the experiences of depression and war forged a “American Century” mindset, leaving the United States in 1945 as an economic and military colossus burdened with new global responsibilities and internal tensions, particularly regarding race and the scope of government, that would define the postwar era.
