Progressive Era & WWI

From 1900 through the 1920s, the United States experienced a wave of social and political reforms known as the Progressive Era. Reformers targeted corruption, improved labor conditions, and promoted consumer protections. Women gained the right to vote with the 19th Amendment in 1920. During this period, the U.S. also entered World War I in 1917, contributing to the Allied victory and shaping its emerging role as a global power. The era combined domestic change with international engagement, setting the stage for modern American society.
