Prior to the establishment of the watch system in England, the pledge system was used. Under this system, each man was responsible for the behavior of his neighbor and had to pledge to apprehend any wrongdoer. This system relied on community involvement and cooperation rather than a formal system of law enforcement. The constable system and posse system were both introduced after the Norman conquest. Community policing, as a modern concept, did not exist during this time period.
