Abstract
In the late nineteenth century, the social consequences of industrialization and urbanization disturbed many people. This led to a reformist surge, which historians call the Progressive movement. ‘1900–1920: Reform and war’ considers events in America domestically and internationally at the turn of the twentieth century and in the run up to, and during World War I. Progressive reformers brought people together to address the social problems arising from urban growth and unregulated corporate social power. However, many of these reformers, mostly white, native born, middle class, shared the era's prejudices and problems. Recognizing the toll of industrialization on nature as well as society, Roosevelt encouraged natural-resource conservation.
