Ludlow massacre

The Ludlow massacre of April 20, 1914 was one of the bloodiest assaults on organized labor in American history. It took place in Ludlow, Colorado (today a ghost town) northwest of Trinidad, Colorado and was the climax of an effort to suppress a strike by twelve thousand Colorado coal miners.
