Red Summer The Red Summer refers to the summer and early autumn of 1919, which was marked by hundreds of deaths and higher casualties across the United States, as a result of race riots that occurred in more than three dozen cities and one rural county. In most instances, whites attacked African Americans. In some cases many black people fought back, notably in Chicago and Washington, D.C. The highest number of fatalities occurred in the rural area around Elaine, Arkansas, where five whites and an estimated 100–240 black people were killed; Chicago and Washington, D.C. had 38 and 15 deaths, respectively, and many more injured, with extensive property damage in Chicago.
