The race riots peaked in Chicago, for the most violence and death occurred there during the riots. The authors of "The Negro in Chicago; a study of race relations and a race riot", an official report from 1922 on race relations in Chicago, came to the conclusion that there were many factors that led to the violent outbursts in Chicago. Principally, many blacks were assuming the jobs of white men who went to go fight in World War I. As the war ended in 1918, many men returned home to find out their jobs had been taken by black men who were willing to work for far less. By the time the rioting and violence had subsided in Chicago, 38 people had lost their lives, with 500 more injured. Additionally, $250,000 worth of property was destroyed, and over a thousand persons were left homeless. In other cities across the nation many more had been affected by the violence of the Red Summer. The Red Summer enlightened many to the growing racial tension in America. The violence in these major cities prefaced the soon to follow Harlem Renaissance, an African-American cultural revolution, in the 1920s. Racial violence appeared again in Chicago in the 1940s and in Detroit as well as other cities in the Northeast as racial tensions over housing and employment discrimination grew.
