The USA after 1917 refers to the period during and after World War I when the United States emerged as a significant global power, shifting from isolationism to a more active international role. This transition was marked by the country's involvement in the war, leading to an expansion of its military, economic, and diplomatic influence worldwide. The end of the war also brought about social changes, including movements for civil rights and women's suffrage, setting the stage for future developments in American society.
