POLICE,

The conception of the police force as a protective and law enforcement organization developed from the use of military bodies as guardians of the peace, such as the Praetorian Guard of ancient Rome. The Romans achieved a high level of law enforcement, which remained in effect until the decline of the empire and the onset of the Middle Ages. Beginning in the 5th century, policing became a function of the heads of fiefdoms and principalities.
