Since 1681
In 1681, William Penn was granted the charter to form a new colony which he intended to call New Wales, but it was soon changed to the name Pennsylvania.
Chester, Pennsylvania became the first capitol and also the birthplace of Pennsylvania law enforcement.
Sheriffs and Constables continued serving in this area under the newly formed colony in a common law tradition.
1797 to present
Communities began hiring police to supplement Elected Law Enforcement (ELE) leaders beginning with the City of Philadelphia in 1797. These employee-based agencies were granted certain borrowed authorities of State Constables. Employees who operate under constable authority are known as ex-officio constables (XOC).
Today, Pennsylvania State Police, County Police, and Municipal Police throughout the state support Elected Sheriffs and Constables in each and every community.
Constables in Pennsylvania are Public Officers under Article VI of the Pennsylvania State Constitution. This is further defined in PA Title 44, Part IV.
