between the military and the police systems in the towns. In charters of the Anglo-Saxon period a haw, or enclosed area within a burh, was often conveyed by charter as if it were an apanage of the lands in the neighbourhood with which it was conveyed; the Norman settlers who succeeded to lands in the county succeeded therewith to houses in the burhs, for a close association existed between the thegns of the shire and the shirestow, an association partly perhaps of duty and also of privilege. The king granted borough haws as places of refuge in Kent, and in London he gave them with commercial privileges to his bishops. What has been called the heterogeneous tenure of the shirestow, one of the most conspicuous characteristics of that particular type of borough, was further increased by the liberty which some burgesses enjoyed to "commend" themselves to a lord of their own choosing, promising to that lord suit and service and perhaps rent in return for protection. Over these burgesses the lords could claim jurisdictional rights, and these were in some cases increased by royal grants of special rights within certain sokes. The great boroughs were honeycombed with sokes, or areas of seignorial jurisdiction, within which the royal reeve's authority was greatly restricted while that of the lord's reeve took precedence. Even the haws, being "burhs" or strongholds within a stronghold, enjoyed a local "peace" which protected from official intrusion. Besides heterogeneity of tenure and jurisdiction in the borough, there was also heterogeneity of status; there were burh-thegns and cnihts, mercatores, burgesses of various kinds, the three groups representing perhaps military, commercial and agricultural elements. The burh generally shows signs of having been originally a village settlement, surrounded by open fields, of which the borough boundary before 1835 will suggest the outline. This area was as a rule eventually the area of borough jurisdiction. There is some evidence pointing to the fact that the restriction of the borough authority to this area is not ancient, but due to the Norman settlement. Boroughs in Norman England The wide districts over which the boroughs had had authority were placed under the control of the Norman castle which was itself built by means of the old English levy of burhwork. The borough court was allowed to continue its work only within its own immediate territory, and, to prevent conflict, the castle was placed outside
