Guild

A guild (/ɡɪld/ GILD) is an association of artisans and merchants who oversee the practice of their craft/trade in a particular territory. The earliest types of guild formed as organizations of tradespeople belonging to a professional association. They sometimes depended on grants of letters patent from a monarch or other ruler to enforce the flow of trade to their self-employed members, and to retain ownership of tools and the supply of materials, but most were regulated by the local government. Guild members found guilty of cheating the public would be fined or banned from the guild. A lasting legacy of traditional guilds are the guildhalls constructed and used as guild meeting-places.

Typically the key "privilege" was that only guild members were allowed to sell their goods or practice their skill within the city. There might be controls on minimum or maximum prices, hours of trading, numbers of apprentices, and many other things. Critics argued that these rules reduced free competition, but defenders maintained that they protected professional standards.

An important result of the guild framework was the emergence of universities at Bologna (established in 1088), Oxford (at least since 1096) and Paris (c. 1150); they originated as guilds of students (as at Bologna) or of masters (as at Paris).

Naram-Sin of Akkad (c. 2254–2218 BC), grandson of Sargon of Akkad who had unified Sumeria and Assyria into the Akkadian Empire, promulgated common Mesopotamian standards for length, area, volume, weight, time, and shekels, which were used by artisan guilds in each city. Code of Hammurabi Law 234 (c. 1755–1750 BC) stipulated a 2-shekel wage for each 60-gur (300-bushel) vessel constructed in an employment contract between a shipbuilder and a ship-owner. Law 275 stipulated a ferry rate of 3-gerah per day on a charterparty between a ship charterer and a shipmaster. Law 276 stipulated a 21⁄2-gerah per day freight rate on a contract of affreightment between a charterer and shipmaster, while Law 277 stipulated a 1⁄6-shekel per day freight rate for a 60-gur vessel.

A type of guild was known in Roman times. Known as collegium, collegia or corpus, these were organised groups of merchants who specialised in a particular craft and whose membership of the group was voluntary. One such example is the corpus naviculariorum, a collegium of merchant mariners based at Rome's La Ostia port. The Roman guilds failed to survive the collapse of the Roman Empire.

A collegium was any association or corporation that acted as a legal entity. In 1816, an archeological excavation in Minya, Egypt produced a Nerva–Antonine dynasty-era (second-century AD) clay tablet from the ruins of the Temple of Antinous in Antinoöpolis, Aegyptus that prescribed the rules and membership dues of a burial society collegium established in Lanuvium, Italia in approximately 133 AD. Following the passage of the Lex Julia in 45 BC, and its reaffirmation during the reign of Caesar Augustus (27 BC–14 AD), collegia required the approval of the Roman Senate or the emperor in order to be authorized as legal bodies. Ruins at Lambaesis date the formation of burial societies among Roman soldiers and mariners to the reign of Septimius Severus (193–211) in 198 AD. In September 2011, archeological investigations done at the site of an artificial harbor in Rome, the Portus, revealed inscriptions in a shipyard constructed during the reign of Trajan (98–117) indicating the existence of a shipbuilders guild. Collegia also included fraternities of priests overseeing sacrifices, practicing augury, keeping religious texts, arranging festivals, and maintaining specific religious cults.

There were several types of guilds, including the two main categories of merchant guilds and craft guilds but also the frith guild and religious guild. Guilds arose beginning in the High Middle Ages as craftsmen united to protect their common interests. In the German city of Augsburg craft guilds are mentioned in the Towncharter of 1156.

The continental system of guilds and merchants arrived in England after the Norman Conquest, with incorporated societies of merchants in each town or city holding exclusive rights of doing business there. In many cases they became the governing body of a town. For example, London's Guildhall became the seat of the Court of Common Council of the City of London Corporation, the world's oldest continuously elected local government, whose members to this day must be Freemen of the city. The Freedom of the City, effective from the Middle Ages until 1835, gave the right to trade, and was only bestowed upon members of a Guild or Livery.
