How did world war 1 change the US?

World War I significantly transformed the United States by marking its emergence as a global power. The war spurred economic growth, leading to industrial expansion and increased job opportunities, particularly for women and minorities. Additionally, the conflict accelerated social changes, including the Great Migration of African Americans to northern cities, and laid the groundwork for the U.S. to take a more active role in international affairs, influencing its foreign policy in the years to come.
