The Ludlow Massacre emanated from a labor conflict: the Colorado National Guard and Colorado Fuel and Iron Company guards attacked a tent colony of 1,200 striking coal miners and their families at Ludlow, Colorado, on April 20, 1914, with the National Guard using machine guns to fire into the colony. Approximately twenty-one people, including miners' wives and children, were killed. The chief owner of the mine, John D. Rockefeller, Jr., was widely excoriated for having orchestrated the massacre.[3][4] Our theme song was written and performed by Anna Bosnick.
