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.
