distraints for debt due, which were obtained through the borough court, were a matter of interest to the burgesses of the court, and first taught the burgesses co-operative action. Money was raised, possibly by order of the borough court, to buy a charter from the king giving the right to choose officers who should answer directly to the exchequer and not through the sheriff of the county. The sheriff was in many cases also the constable of the castle, set by the Normans to overawe the English boroughs; his powers were great and dangerous enough to make him an officer specially obnoxious to the boroughs. Henry I about 1131 gave the London citizens the right to choose their own sheriffs and a justiciar answerable for keeping the pleas of the crown. In 1130 the Lincoln citizens paid to hold their city in chief of the king. By the end of the 12th century many towns paid by the hand of their own reeves, and John's charters began to make rules as to the freedom of choice to be allowed in the nomination of borough officers and as to the royal power of dismissal. In Richard I's reign London imitated the French communes in styling the chief officer a mayor; in 1208 Winchester also had a mayor, and the title soon became no rarity. The chartered right to choose two or more citizens to keep the pleas of the crown gave to many boroughs the control of their coroners, who occupied the position of the London justiciar of earlier days, subject to those considerable modifications which Henry II's systematisation of the criminal law had introduced. Burgesses who had gone for criminal and civil justice to their own court in disputes between themselves, or between themselves and strangers who were in their town, secured confirmation of this right by charter, not to exclude the justices in eyre, but to exempt themselves from the necessity of pleading in a distant court. The burgess, whether plaintiff or defendant, was a privileged person, and could claim in this respect a "benefit" somewhat similar to the benefit of clergy. In permitting the boroughs to answer through their own officers for his dues, the king handed over to the boroughs the farming of his rents and a large number of rights which would eventually prove to be sources of great profit.
