The condition at the close of the First World War was greatly intensified. because statistics show that during that .war. and immediately following. more than 1.000.000 Negroes migrated from the South to the North. into the industrial sections of the country. Many of them did not see fit to return to their homes in the South. Many of them possibly could not. and. for one reason or another. large numbers of them remained in the industrial centers to which they had migrated as a result of war activities in World War I. By reason of the friction which sprang up in those industrial communitiesand they were not in the South but in the North and Eastriots occurred following World War I. which created a very great problem in the communities where the migrant laborers had gone. and where they remained.
