On this day, 10 September 1897, 19 unarmed striking coal miners and mine workers were killed and 36 wounded near Lattimer, Pennsylvania, for refusing to disperse, by a posse organized by the Luzerne County sheriff. The strikers, most of whom were shot in the back, were migrant workers originally brought in as strike-breakers, but later organised themselves. The killers were put on trial but all were acquitted. However the massacre marked a turning point in mine workers’ organisation in the United States: and miners, particularly migrant workers, flooded into the United Mine Workers union and won big improvements. https://www.facebook.com/workingclasshistory/photos/a.296224173896073/1207471092771372/?type=3
