Many boroughs sought and obtained formal incorporation with the same essential features as London. This tied up the loose language of their early charters of liberties. Often, a borough would have its own resident Justice of the Peace. Each incorporation involved a review by a Justice of the Peace to make sure the charter of incorporation rule didn't conflict with the law of the nation. A borough typically had a mayor accompanied by his personal sword- bearer and serjeants-at-mace bearing the borough regalia, bailiffs, a sheriff, and chamberlains or a steward for financial assistance. At many boroughs, aldermen, assisted by their constables, kept the peace in their separate wards. There might be coroners, a recorder, and a town clerk, with a host of lesser officials including beadles, aletasters, sealers, searchers [inspectors], weighers and keepers of the market, ferrymen and porters, clock-keepers and criers, paviors [maintained the roads], scavengers and other street cleaners, gatekeepers and watchmen of several ranks and kinds. A wealthy borough would have a chaplain and two or three minstrels. The mayor replaced the bailiffs as the chief magistracy. In all towns, the wealthiest and most influential guilds were the merchant traders of mercers, drapers, grocers, and goldsmiths. From their ranks came most of the mayors, and many began to intermarry with the country knights and gentry. Next came the shopholders of skinners, tailors, ironmongers, and corvisors [shoemakers]. Thirdly came the humbler artisans, the sellers of victuals, small shopkeepers, apprentices, and journeymen on the rise. Lastly came unskilled laborers, who lived in crowded tenements and hired themselves out. The first three groups were the free men who voted, paid scot and bore lot, and belonged to guilds. Scot was a rateable proportion in the payments levied from the town for local or national purposes. Merchant guilds in some towns merged their existence into the town corporation, and their guild halls became the common halls of the town, and their property became town property. In London, the Cutlers' Company was chartered in 1415, the Haberdashers' Company in 1417, the Grocers' Company in 1428, the Drapers' and Cordwainers' companies in 1429, the Vintners' and Brewers' companies in 1437, the Leathersellers' Company in 1444, the Girdlers' Company in 1448, the Armourers' and Brassiers' companies in 1453, the Barbers' Company in 1461, the Tallow Chandlers' Company in 1462, the Ironmongers' Company in 1464, the Dyers' Company in 1471, the Musicians' Company in 1472, the Carpenters' Company in 1477, the Cooks' Company in 1481, and the Waxchandlers' Company in 1483.
