FRANKPLEDGE (Lat. _francum plegium_), an early English institution, consisting (as defined by Stubbs) of an association for mutual security whose members, according to Hallam, "were perpetual bail for each other." The custom whereby the Inhabitants of a district were responsible for any crime or injury committed by one of their number is old and widespread; it prevailed in England before the Norman Conquest, and is an outcome of the earlier principle whereby this responsibility rested on kinship. Thus a law of Edgar (d. 975) says "and let every man so order that he have a _borh_ (or surety), and let the borh then bring and hold him to every justice; and if any one then do wrong and run away, let the borh bear that which he ought to bear"; and a law of Canute about 1030 says "and that every one be brought into a hundred and in borh, and let the borh hold and lead him to every plea." About this time these societies, each having its headman, were called _frithborhs_, or peace-borhs, and the Normans translated the Anglo-Saxon word by frankpledge. But the history of the frankpledge proper begins not earlier than the time of the Norman Conquest. The laws, which although called the laws of Edward the Confessor were not drawn up until about 1130, contain a clause about frithborhs which decrees that in every place societies of ten men shall be formed for mutual security and reparation. And before this date William the Conqueror had ordered that "every one who wishes to be regarded as free must be in a pledge, and that the pledge must hold and bring him to justice if he commits any offence"; and the laws of Henry I. ordered every person of substance over twelve years of age to be enrolled in a frankpledge. This association of ten, or as it often was at a later date of twelve men, was also called a _tithing_, or _decima_, and in the north of England was known as _tenmanne_ tale.
