The incorporation of the Cinque Ports had its origin in the necessity for some means of defence along the southern seaboard of England, and in the lack of any regular navy. Up to the reign of Henry VII. they had to furnish the crown with nearly all the ships and men that were needful for the state; and for a long time after they were required to give large assistance to the permanent fleet. The oldest charter now on record is one belonging to the 6th year of Edward I.; and it refers to previous documents of the time of Edward the Confessor and William the Conqueror. In return for their services the ports enjoyed extensive privileges. From the Conquest or even earlier they had, besides various lesser rights--(1) exemption from tax and tallage; (2) soc and sac, or full cognizance of all criminal and civil cases within their liberties; (3) tol and team, or the right of receiving toll and the right of compelling the person in whose hands stolen property was found to name the person from whom he received it; (4) blodwit and fledwit, or the right to punish shedders of blood and those who were seized in an attempt to escape from justice; (5) pillory and tumbrel; (6) infangentheof and outfangentheof, or power to imprison and execute felons; (7) mundbryce (the breaking into or violation of a man's _mund_ or property in order to erect banks or dikes as a defence against the sea); (8) waives and strays, or the right to appropriate lost property or cattle not claimed within a year and a day; (9) the right to seize all flotsam, jetsam, or ligan, or, in other words, whatever of value was cast ashore by the sea; (10) the privilege of being a gild with power to impose taxes for the common weal; and (11) the right of assembling in portmote or parliament at Shepway or Shepway Cross, a few miles west of Hythe (but afterwards at Dover), the parliament being empowered to make by-laws for the Cinque Ports, to regulate the Yarmouth fishery, to hear appeals from the local courts, and to give decision in all cases of treason, sedition, illegal coining or concealment of treasure trove. The ordinary business of the ports was conducted in two courts known respectively as the court of brotherhood and the court of brotherhood and guestling,--the former being composed of the mayors of the seven principal towns and a number of jurats and freemen from each, and the latter including in addition the mayors, bailiffs and other representatives of the corporate members. The court of brotherhood was formerly called the brotheryeeld, brodall or brodhull; and the name guestling seems to owe its origin to the fact that the officials of the "members" were at first in the position of invited guests.
