The history of the race massacre in Elaine, Arkansas, has always been contested.

It is widely accepted that in 1919, a group of white men, with the backing of federal troops, tortured and killed scores of Black residents - the exact number is disputed but assumed to number at least in the hundreds - who were starting to organize against the exploitation of their labor. The massacre came at the tail end of what would become known as the red summer", a season of racial terror fueled by white resentment of the strides Black people were making across the country.
