The counties of England are territorial divisions of
England for the purposes of administrative, political and geographical demarcation. Many current counties have foundations in older divisions such as the
Anglo-Saxon kingdoms.The names, boundaries and functions of these divisions have changed considerably in modern times. Indeed, a series of local government reforms from the 19th century onwards has left the exact definition of the term 'county' ambiguous. The term "counties of England" does not, therefore, refer to a unique canonical set of names or boundaries; in formal use, the type of county relevant to the specific task and period is explicitly stated e.g.
ceremonial county,
registration county,
historic county or
former postal county.
