After the war, fear of subversion resumed in the context of the Red Scare, massive strikes in major industries (steel, meatpacking) and violent race riots. Radicals bombed Wall Street, and workers went on strike in Seattle in February. During 1919, a series of more than 20 riotous and violent black-white race-related incidents occurred. These included the Chicago, Omaha, and Elaine Race Riots.
