Dangerous Anarchist Strikes explores the ideas of three largely forgotten radical women who participated in labor union strikes in Argentina and Uruguay, Canada, and the United States: Virginia Bolten (c.1876-1960), one of the most militant anarchists of southern South America; Helen Armstrong (1875-1947), a major leader of the Winnipeg General Strike of 1919, whose involvement in that important event in Canadian history was, for a long time, obscured by accounts that emphasized the accomplishments of men; and Elizabeth Gurley Flynn (1890-1964), the Wobbly leader who directed many industrial strikes throughout the United States, and was one of the founders of the American Civil Liberties Union, who eventually became the leader of the Communist Party, USA.
The book also examines the contributions of two similarly neglected anarchist men who participated in labor union strikes and industrial action in New Zealand, Australia, Chile, Argentina, and Japan. Tom Barker (1887-1970), who was an anarchist who eventually became a socialist, worked to promote labor unionism on four continents, and who tried to create a global One Big Union for sailors. Kōtoku, Shūsui (1871-1911) was a liberal who became a socialist and finally an anarchist. An opponent of governmental imperialism and ecological mismanagement, he studied and translated the works of Western thinkers and sought to apply what he learned from other cultures to the development of Japan.
