Later in the towns, there were merchant guilds, which were composed of prosperous traders, who later became landholders. Merchant guilds grew out of charity associations whose members were bound by oath to each other and got together for a guild-feast every month. Many market places were dominated by a merchant guild, which had a monopoly of the local trade. There were also some craft guilds composed of handicraftsmen or artisans. Escaped bonded agricultural workers, poor people, and traders without land migrated to towns to live, but were not citizens. Towns were largely self-sufficient, but salt and iron came from a distance. It was the kings' policy to establish in every shire at least one town with a market place where purchases would be witnessed and a mint where reliable money was coined. Almost every village had a watermill. Edward the Confessor, named such for his piety, was a King of 24 years who was widely respected for his intelligence, resourcefulness, good judgment, and wisdom. His educated Queen Edith, whom he relied on for advice and cheerful courage, was a stabilizing influence on him. They were served by a number of thegns, who had duties in the household, which was composed of the hall, the courtyard, and the bedchamber. They were important men, thegns by rank. They were landholders, often in several areas, and held leading positions in the shires, although they were not sheriffs. They were also priests and clerics, who maintained the religious services and performed tasks for which literacy was necessary. The court was host to many of the greatest magnates and prelates of the land at the time of great ecclesiastical festivals, when the King held more solemn courts and feasted his vassals. These included all the great earls, the majority of bishops, some abbots, and a number of thegns and clerics. Edward had a witan of wise men to advise him, but sometimes the King would speak in the hall after dinner and listen to what comments were made from the mead-benches. As the court moved about the country, many men came to pay their respects and attend to local business.
