Centralia Massacre (Washington)

The Centralia Massacre, also known as the Armistice Day Riot, was a violent and bloody incident that occurred in Centralia, Washington, on November 11, 1919, during a parade celebrating the first anniversary of Armistice Day. This conflict between the American Legion and workers who were members of the Industrial Workers of the World (IWW or "Wobblies") resulted in six deaths, additional wounded, multiple prison terms, and an ongoing and especially bitter dispute over the motivations and events that precipitated the massacre. It was the culmination of years of bad blood between members of the local Legion and members of the IWW. Both Centralia and the neighboring town of Chehalis had a large number of World War I veterans, with robust chapters of the Legion, as well as a large number of IWW members, some also war veterans.
