The word is often rendered in Latin as praefectus (Modern English prefect), by the historian Bede, and some early Anglo-Saxon charters. West-Saxon charters prefer to reserve the term praefectus for the ealdormen (earls) themselves.
After the Conquest
After the Norman conquest, feudalism was introduced, forming a parallel administrative system to the local courts. The feudal system organised land on a manorial basis, with stewards acting as managers for the landlords. The Norman term describing the court functionary—bailiff—came to be used for reeves associated with lower level courts, and with the equivalent role in the feudal courts of landlords.
Courts fulfilled administrative, as well as judicial, functions, and on the manorial level its decisions could concern mundane field management, not just legal disputes. The manorial bailiff thus could be set tasks such as ensuring certain crops were gathered, as well as those like enforcing debt repayment. Sometimes, bailiffs would have assistants to carry out these tasks, and the term reeve now came to be used for this position—someone essentially assisting the steward, and sometimes a bailiff, by effectively performing day-to-day supervision of the work done on the land within a particular manor.
