perpetrated by whites in blackface." They went on to report that the riot was planned and begun by "the vice element of the city." The riot "was not a casual affair; it was premeditated and planned by those secret and invisible forces that today are fighting you and the men who represent good government." Racial tension The event was part of an ongoing racial tension in Omaha in the early 20th century. There were attacks on Greek immigrants in 1909. The migration of many blacks into the city pursuing economic opportunities sparked racial tension in the state. After the Omaha riot, the Ku Klux Klan became established in 1921. Another racial riot took place in North Platte, Nebraska in 1929. There were also violent strikes in the Omaha meat packing industry in 1917 and 1921 and concerns about immigrants from Southern and Eastern Europe. After the riot, the city of Omaha, previously a city in which ethnicities and races were mixed in many neighborhoods, became more segregated. Redlining and restrictive covenants began to be used in new neighborhoods, with African Americans restricted to owning property where they already lived in greatest number, in North Omaha. Although segregation has not been legally enforced for generations, a majority of Omaha's black population still lives in North Omaha. Legacy In the fall of 1920, Dr. George E. Haynes, an educator employed as Director of Negro Economics at the U.S. Department of Labor, produced a report on that year's racial violence designed to serve as the basis for an investigation by the U.S. Senate Committee on the Judiciary. It cataloged 26 separate riots on the part of whites attacking blacks in widely scattered communities. Together with other riots in 1919, the Omaha riot prompted the United States Senate Committee on Judiciary in October 1919 to call for an investigation of urban, industrial and racial problems. The committee members recognized lynchings as a justified cause of bitterness in the black community, and enumerated the riots of 1919 and lynchings as among the factors for its investigation. They called for leaders of the white and black communities to work toward reconciliation. In September 1918, President Woodrow Wilson had made a speech against lynching and mob violence. Although a few years later Congress tried to pass a law making lynching a Federal offense, action was blocked by Southern Democrats. James Joyce, in a 1919 draft of his
