Many new boroughs were founded as grants of market rights by the King grew in number. These grants implied the advantage of the King's protection. In fact, a certain flooded town was replaced with a new town planned with square blocks. It was the charter which distinguished the borough community from the other communities existing in the country. It invested each borough with a distinct character. The privileges which the charter conferred were different indifferent places. It might give trading privileges: freedom from toll, a guild merchant, a right to hold a fair. It might give jurisdictional privileges: a right to hold court with greater or less franchises. It might given governmental privileges: freedom from the burden of attending the hundred and county courts, the return of writs, which meant the right to exclude the royal officials, the right to take the profits of the borough, paying for them a fixed sum to the Crown or other lord of the borough, the right to elect their own officials rather than them being appointed by the King or a lord, and the right to provide for the government of the borough. It might give tenurial privileges: the power to make a will of lands, or freedom from the right of a lord to control his tenants' marriages. It might give procedural privileges: trial by battle is excluded, and trial by compurgation is secured and regulated. These medieval borough charters are very varied, and represent all stages of development and all grades of franchise. Boroughs bought increasing rights and freedoms from their lord, who was usually the King. In the larger towns, where cathedrals and public building were built, there arose a system for teaching these technical skills and elaborate handicraft, wood, metal, stained glass, and stone work. Some churches now had stained-glass windows. A boy from the town would be bound over in apprenticeship to a particular craftsman, who supplied him with board and clothing. The craftsman might also employ men for just a day. These journeymen were not part of the craftsman's household as was the apprentice. After a few years of an apprenticeship, one became a journeyman and perfected his knowledge of his craft and its standards by seeing different methods and results in various towns. He was admitted as a master of his trade to a guild upon presenting an article of his work worthy of that guild's standard of workmanship: his "masterpiece". The tailors' guild and the skinners' guild are extant now. When guilds performed morality plays based on Bible stories at town festivals, there was usually a tie between the Bible story and the guild's craft. For instance, the story of the loaves and fishes would be performed by the Bakers' or Fishmongers' Guild. The theme of the morality play was the fight of the Seven Cardinal Virtues against the Seven Deadly Sins for the human soul, a life-long battle.
