On the Thames River to London were large ships with cargoes; small boats rowed by tough boatmen offering passage for a penny; small private barges of great men with carved wood, gay banners, and oarsmen with velvet gowns; the banks covered with masts and tackle; the nineteen arch London Bridge supporting a street of shops and houses and a drawbridge in the middle; quays; warehouses, and great cranes lifting bales from ship to wharf. Merchant guilds which imported or exported each had their own wharves and warehouses. Downstream, pirates hung on gallows at the low-water mark to remain until three tides had overflowed their bodies. A climate change of about 1 1/2 degree Celcius lower caused the Thames to regularly freeze over in winter.

The large scale of London trade promoted the specialization of the manufacturer versus the merchant versus the shipper. Merchants had enough wealth to make loans to the government or for new commercial enterprises. Local reputation on general, depended upon a combination of wealth, trustworthiness of character, and public spirit; it rose and fell with business success. Some London merchants were knighted by the King. Many bought country estates and turned themselves into gentry.

The king granted London all common soils, improvements, wastes, streets, and ways in London and in the adjacent waters of the Thames River and all the profits and rents to be derived therefrom. Later the king granted London the liberty to purchase lands and tenements worth up to 2,667s. yearly. With this power, London had obtained all the essential features of a corporation: a seal, the right to make by-laws, the power to purchase lands and hold them "to them and their successors" (not simply their heirs, which is an individual and hereditary succession only), the power to sue and be sued in its own name, and the perpetual succession implied in the power of filling up vacancies by election. Since these powers were not granted by charters, London is a corporation by prescription. In 1446, the liverymen obtained the right with the council to elect the mayor, the sheriff, and certain other corporate officers.

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. The Fishmongers, which had been chartered in 1399, were incorporated in 1433, the Cordwainers in 1439, and the Pewterers in 1468.

There were craft guilds in the towns, at least 65 in London. In fact, every London trade of twenty men had its own guild. The guild secured good work for its members and the members maintained the reputation of the work standards of the guild. Bad work was punished and night work prohibited as leading to bad work. The guild exercised moral control over its members and provided sickness and death benefits for them. There was much overlapping in the two forms of association: the craft guild and the religious fraternity. Apprentices were taken in to assure an adequate supply of competent workers for the future. The standard indenture of an apprentice bound him to live in his master's house, to serve him diligently, obey reasonable commands, keep his master's secrets, protect him from injury, abstain from dice, cards and haunting of taverns, not marry, commit no fornication, nor absent himself without permission. In return the master undertook to provide the boy or girl with bed, board, and lodging and to instruct him or her in the trade, craft, or mystery. When these apprentices had enough training they were made journeymen with a higher rate of pay. Journeymen traveled to see the work of their craft in other towns. Those journeymen rising to master had the highest pay rate.

Occupations free of guild restrictions included horse-dealers, marbelers, bookbinders, jewelers, organ makers, feathermongers, pie makers, basket makers, mirrorers, quilters, and parchment makers. Non-citizens of London could not be prevented from selling leather, metalwares, hay, meat, fruit, vegetables, butter, cheese, poultry, and fish from their boats, though they had to sell in the morning and sell all their goods before the market closed.

In the towns, many married women had independent businesses and wives also played an active part in the businesses of their husbands. Wives of well-to-do London merchants embroidered, sewed jewelry onto clothes, and made silk garments. Widows often continued in their husband's businesses, such as managing a large import-export trade, tailoring, brewing, and metal shop. Socially lower women often ran their own breweries, bakeries, and taverns. It was possible for wives to be free burgesses in their own right in some towns.

Some ladies were patrons of writers. Some women were active in prison reform in matters of reviews to insure that no man was in gaol without due cause, overcharges for bed and board, brutality, and regulation of prisoners being placed in irons. Many men and women left money in their wills for food and clothing for prisoners, especially debtors. Wills often left one-third of the wealth to the church, the poor, prisoners, infirmaries, young girls' education; road, wall, and bridge repair; water supply, markets and almshouses. Some infirmaries were for the insane, who were generally thought to be possessed by the devil or demons. Their treatment was usually by scourging the demons out of their body by flogging. If this didn't work, torture could be used to drive the demons from the body.
