This book examines the regional history of the American West in relation to the rest of the United States, emphasizing cultural and political history.

The American West has influenced important national developments throughout the twentieth century, not only in the cultural arena, but also in economic development, in political ideology and action, and in natural resource conservation and preservation. Using regionalism as a lens for illuminating these national trends, America's West: A History, 1890–1950 examines this region's history and explores its influence on the rest of America. Moving chronologically from the late nineteenth- to the mid-twentieth century, David M. Wrobel examines turn-of-the-century expansion, the Progressive Era, the 1920s, the Great Depression and the New Deal, World War II, and the early Cold War years. He emphasizes cultural and political history, showing how developments in the West frequently indicated the future direction of the country.
