A charter of Henry I in about 1130 gave the City of London its own Sheriff. The Sheriff of London also had jurisdiction over the county of Middlesex, so that "London and Middlesex were from that time regarded as one from an administrative point of view", although they retained their separate identities. This relationship continued until the Local Government Act 1888 created a new office of High Sheriff of Middlesex appointed in the same manner as other English and Welsh counties, created the County of London with its own high sheriff, and restricted the jurisdiction of the sheriffs of London to the City.
