In the early 20th century, Montana was a center of activity for the Industrial Workers of the World (IWW), a radical labor organization that advocated for the overthrow of capitalism and the establishment of a worker-controlled society. The state was the site of several major strikes and labor conflicts during this time, including the Anaconda Road Massacre of 1920, in which striking miners were killed by National Guard troops.
