Emergence of Modern America
1890-1930

The idea of a “Modern United States” begins with the advent of the Progressive era. The Progressive movement focused on reforms viewed as necessary after drastic increases in industrialization, immigration, and urbanization, as well as corruption in the business and political realms. Temperance reached its peak with the 18th Amendment and the decade of Prohibition, while woman suffrage became guaranteed nationally with the 19th Amendment. Other movements that gained traction on a new scale during this era were the labor movement, including the rise of unions, and the Harlem Renaissance. Shifting roles for African Americans migrating to northern cities and unprecendented immigration to America's shores heightened racial and ethnic tensions and led to the resurgence of the Ku Klux Klan.

With all of the changes on the home front of America, this era also saw the emergence of the United States as a major world power. The Spanish-American War pitted the U.S. against a European power other than Great Britain for the first time. Not long after, the United States found itself embroiled in World War I, despite strong isolationist tendencies. Along with a large death toll, World War I led to the development of the failed League of Nations, ultimately pushing the United States even further into an isolationist standing that would last for decades. The immediate postwar period of the Prohibition-era “Roaring 20s” saw a domination in politics and economics by big business and its supporters, which would all come crashing down in less than a decade.
