How did world war 1 change the lives of African Americans?

More than 350,000 African Americans served in segregated units during World War I, mostly as support troops. Several units saw action alongside French soldiers fighting against the Germans, and 171 African Americans were awarded the French Legion of Honor. In response to protests of discrimination and mistreatment from the black community, several hundred African American men received officers' training in Des Moines, Iowa. By October 1917, over six hundred African Americans were commissioned as captains and first and second lieutenants.
