Athens, a group of 300 Scythian slaves was used to guard public meetings to keep order and for crowd control, and also assisted with dealing with criminals, manhandling prisoners, and making arrests. Other duties associated with modern policing, such as investigating crimes, were left to the citizens themselves. The Roman Empire had a reasonably effective law enforcement system until the decline of the empire, though there was never an actual police force in the city of Rome. When under the reign of Augustus the capital had grown to almost one million inhabitants, he created 14 wards, which were protected by seven squads of 1,000 men. If necessary, they might have called on the Praetorian Guard for assistance. Beginning in the 5th century, policing became a function of clan chiefs and heads of state. During the Middle Ages, crime and punishment were dealt with through blood feuds (or trial by ordeal) between the parties.

For those who could not afford to buy their way out of punishment, harsh penalties included various forms of corporal punishment. These included mutilation, whipping, branding, and flogging, as well as execution. Västgötalagen specifies exactly how much to pay, if anything, depending on who was slain. The primary form of state-administered punishment during ancient times and the Middle Ages was banishment or exile.

Rather, it was used to detain prisoners before trial or for imprisoning people without judicial process. The Anglo-Saxon system of maintaining public order was a private system of tithings, since the Norman conquest led by a constable, which was based on a social obligation for the good conduct of the others; more common was that local lords and nobles were responsible to maintain order in their lands, and often appointed a constable, sometimes unpaid, to enforce the law. Colonial America When early colonists first came to America, they did not include trained lawyers or other law-knowledgeable persons. Many parts of the criminal justice system in colonial America were similar to those in England, France, and the Dutch Republic. Gradually French and Dutch influences disappeared in the islands. What remained was the basic idea many had of the English common law system. This system
