Hartford coal mine riot

The Hartford coal mine riot occurred on July 12, 1914, at Hartford, Arkansas. In a productive region of a state with 100% of its coal miners represented by the United Mine Workers (UMW), one mine owner attempted to open a non-union shop. In the resulting conflict, mines were flooded by sabotage, and on July 17 a crowd of union miners and sympathizers destroyed the surface plant of the Prairie Creek coal mine #3 and murdered two non-union miners.^[1]

Resulting litigation in federal courts stretched to an out-of-court settlement of a nominal $27,500 in 1927.
