Calvin Coolidge lived during a time of constitutional transformation – the Progressive Era and World War I – before serving as President of the United States from 1923-1929. Thomas J. Tacoma argues that Coolidge contended with this changing regime and world through as a Burkean conservative and an Americanist politician. In The Political Thought of Calvin Coolidge: Burkean Americanist, Tacoma contextualizes Coolidge’s thought in the Progressive milieu of the age and Coolidge’s own educational background in New England and then presents the core of Coolidge’s political thought: civilization. Tacoma maintains that Coolidge believed in civilization and that the traditional American political and economic order represented the highest achievements in western civilization. Coolidge’s speeches ranged across American history to defend the virtues of the American regime, and in his political career, he undertook to defend the constitutional regime he had inherited. Coolidge, famous for his emphasis on thrift, likewise situated his views on economy within his larger vision of civilization, and he mixed realism and idealism in his developed views on international relations. Through extensive research, Tacoma examines the way Coolidge responded to the challenge of upholding American civilization in the face of a changing world.
