An examination of the causes, prosecution and legacy of the Great War, World War I, from the perspective of American involvement. Robert H. Zieger seeks to illuminate both America’s dramatic influence on the war and the war’s considerable impact upon America. His narrative provides descriptions of the famous battles and diplomatic manoeuvring, while also chronicling America’s rise to prominence within the postwar world. On the domestic front, Zieger details how the war forever altered American politics and society by creating the National Security State, generating powerful new instruments of social control, bringing about innovative labour and social welfare programmes, and redefining civil liberties and race relations.
