How did world war 1 encourage social change in the US?

Answer 1

While men are off fighting the war, women were left to take over their (male dominated) jobs and so women were allowed more rights and soon was granted the right to vote in 1920.

Answer 2

World War 1 encouraged social change in the US by giving women the opportunity to work in jobs typically held by men, leading to the women's suffrage movement and ultimately the passage of the 19th Amendment. The war also sparked a wave of African American migration from the rural South to urban areas in the North for employment, contributing to the Great Migration and the growth of African American communities and cultural expression. Additionally, the war stimulated the expansion of the federal government's role in the economy and society, setting the stage for increased government intervention and regulation in the decades to come.
