Lynchings were violent public acts that white people used to terrorize and control Black people in the 19th and 20th centuries, particularly in the South
National lynching rates declined in the 1930s, a trend that NAACP Executive Secretary Walter White attributed to anti-lynching activism, shifts in public opinion, and the Great Migration
After WWI, racial violence worsened, the most horrific example being a massacre that took place in East St Louis in 1917 that left over 100 black people dead, and an entire neighbourhood reduced to ashes
Black soldiers also had a trying experience, as the army remained rigidly segregated and the War Department relegated the majority of black troops to labour duties
In the months following the armistice, racial tensions across the country increased, and race riots erupted across the country, notably in Washington D.C and Chicago
The "Red Summer" of 1919 marked the culmination of steadily growing tensions surrounding the great migration of African Americans from the rural South to the cities of the North that took place during World War I
In the aftermath of the rioting in Chicago, the Chicago Commission on Race Relations was organized to investigate the root causes of the riots and find ways to combat them
President Woodrow Wilson publicly blamed white people for being the instigators of race-related riots in both Chicago and Washington, D.C., and introduced efforts to foster racial harmony
