Pennsylvania's Coal and Iron Police (Images of America)

Pennsylvania's Coal and Iron Police ruled small patch towns and industrial cities for their coal and iron company bosses from 1865 to 1931. Armed with a gun and badge and backed by state legislation, the members of the private police force were granted power in a practically unspecified jurisdiction. Set in Pennsylvania's anthracite and bituminous regions, including Luzerne, Schuylkill, Westmoreland, Beaver, Somerset, and Indiana Counties, at a time when labor disputes were deadly, the officers are the story behind American labor history's high-profile events and attention-grabbing headlines. Paid to protect company property, their duties varied but unfortunately often resulted in strikebreaking, intimidation, and violence.
