Garvey began calling for armed self-defense

In the wake of the East St. Louis Race Riots in May to July 1917, in which white mobs targeted black people, Garvey began calling for armed self-defense. He produced a pamphlet, "The Conspiracy of the East St Louis Riots", which was widely distributed; proceeds from its sale went to victims of the riots. The Bureau of Investigation began monitoring him, noting that in speeches he employed more militant language than that used in print; it for instance reported him expressing the view that "for every Negro lynched by whites in the South, Negroes should lynch a white in the North".
