This book has examined the racial riots that erupted in four different communities of America in the years after World War I: Knoxville in Tennessee, Elaine in Arkansas, Tulsa in Oklahoma, and Chicago in Illinois. It has shown that blacks were the victims of these riots and identified racial tension between blacks and whites as the underlying cause. The book has also looked at the differing reasons for each conflict. The Knoxville riot stemmed from sexual criminality, while the Elaine riot had something to do with economic betterment and repression. The Tulsa situation was attributed to sexual, social, and economic inequities, and the Chicago problem to white and black economic competition and social injustice. Nevertheless, all four racial riots arose from the troubled history of racially torn America. Racial riots are solid evidence of the injustices of racial relations in the country, which emerged as a new form of revenge after lynching came under national attack.
