The period from 1913 to 1933 is not often seen as a coherent entity in the history of the United States. It is more often viewed in terms of two distinct periods with the pre-war era of political engagement, idealism, and reform known as "progressivism" separated by World War I from the materialism, conservatism and disengagement of the "prosperous" 1920s. To many postwar observers and later historians, the entry of the United States into the European conflict in 1917 marked not just a dramatic departure in foreign relations, but also the end of an era of reform.

This second edition of Historical Dictionary from the Great War to the Great Depression covers the history of this period through a chronology, an introductory essay, appendixes, and an extensive bibliography. The dictionary section has more than 700 cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent access point for students, researchers, and anyone wanting to know more about a vital period in U.S. history.
