The Cripple Creek miners' strike of 1894 was a five-month strike by the Western Federation of Miners (WFM) in Cripple Creek, Colorado, United States. It resulted in a victory for the union and was followed in 1903 by the Colorado Labor Wars. It is notable for being the only time in United States history when a state militia was called out (May/June 1894) in support of striking workers.The strike was characterized by firefights and use of dynamite, and ended after a standoff between the Colorado state militia and a private force working for owners of the mines. In the years after the strike, the WFM's popularity and power increased significantly through the region.
