On September 10, 1897, a group of 400 striking coal miners--workers of Polish, Slovak, and Lithuanian descent or origin--marched on Lattimer, Pennsylvania. There, law enforcement officers fired without warning into the protesters, killing nineteen miners and wounding thirty-eight others. The bloody day quickly faded into history. Paul A. Shackel confronts the legacies and lessons of the Lattimer event. Beginning with a dramatic retelling of the incident, Shackel traces how the violence, and the acquittal of the deputies who perpetrated it, spurred membership in the United Mine Workers. By blending archival and archaeological research with interviews, he weighs how the people living in the region remember--and forget--what happened. Now in positions of power, the descendants of the slain miners have themselves become rabidly anti-union and anti-immigrant as Dominicans and other Latinos change the community. Shackel shows how the social, economic, and political circumstances surrounding historic Lattimer connect in profound ways to the riven communities of today. Compelling and timely, Remembering Lattimer restores an American tragedy to our public memory.
