Progressive Era.

Regardless of exactly when it began or ended, a point that scholars have disagreed upon, the Progressive Era was a time of major change in the United States. Some suggest that it began as early as 1890 and that it extended into the 1930s with the election of President Franklin Roosevelt and his New Deal program, which established social welfare in the United States. Progressivism was propelled by middle- and upper class reformers with a strong sense of social justice, and progressive changes directly impacted politics, economics, education, society, medicine, and the arts. The Progressive movement sought both social and political reform in the United States.
