A century ago this week, a long-simmering conflict between miners on strike in the southern Colorado coalfields and troops of the Colorado National Guard erupted into the deadliest labor war in American history. A raging gun battle on April 20, 1914, resulted in the destruction of the strikers' Ludlow tent colony and the deaths of nearly two dozen people -- most of them women and children who'd sought refuge from the shooting in a small cellar under one of the tents. The Ludlow Massacre, as it became known, is one of the darkest yet most neglected chapters of state history -- but a slew of commemorative events planned to mark its hundredth anniversary could help change that.
The Ludlow Memorial.
