On April 19 and 20, 1914, during a miner strike in Colorado, the National Guard killed dozens of people—though the exact number of casualties is disputed, most sources agree that at least four women and 11 children were among the dead. When the workers first went on strike, they were evicted from the company-owned houses in the mining town, so they set up massive tent colonies outside of the towns. The workers were protesting for higher wages and better work qualities but were making very little progress.
