Alanson B. Houghton—American industrialist, politician, and diplomat—was the world's most influential diplomat during the "New Era" of the 1920s.

Houghton, who served as ambassador to both Germany (1922–1925) and Great Britain (1925–1929), offers a unique window into the formation and implementation of American foreign policy. This fascinating new text by Jeffrey J. Matthews provides a clear and concise account of Houghton's diplomatic experience and consequently a fresh assessment of U.S. foreign policy during a pivotal decade in world history.

As the leading ambassador in Europe, Houghton played a key role in the major diplomatic achievements of the era, including the Dawes Plan for reparations, the Locarno security treaties, and the Kellogg-Briand peace pact. While Houghton's significant contributions to these international accords are fully explored, the major theme of this book is his emergence as chief critic of U.S. foreign policy within the Harding and Coolidge administrations.

Alanson B. Houghton: Ambassador of the New Era offers students a concise historical narrative and a substantive reevaluation of 1920s American foreign policy. This text will help students understand why the United States failed to establish a stable world order during the New Era and additionally sheds light on the key historiographical themes of isolationism, new-imperialism, and corporations. For students taking courses on the Gilded Age, the interwar years, and U.S. foreign policy, this new volume will be an invaluable resource.
