The oldest of the City Companies now existing is the Weavers' Company, having received its charter from Henry II. Though licensed, these trade organizations were not incorporated until the reign of Edward III., who generously enrolled himself as a member of the Merchant Tailors.
At this time it was ordained that all artificers should choose their trade, and, having chosen it, should practise no other; hence it was that these "Guilds" grew to such a position of wealth and influence, the ancient prototype, doubtless, of the modern "labour unions."
The twelve great City Companies, whose governors ride about in the lord mayor's procession of the 9th of November of each year, are, in order of precedence, ranked as follows: Mercers, Grocers, Drapers, Fishmongers, Goldsmiths, Skinners, Merchant Tailors, Haberdashers, Salters, Ironmongers, Vintners, Cloth-workers.
Allied with these are eighty odd other companies divided into three classes:
I. Those exercising a control over their trades: Goldsmiths, Apothecaries.
II. Those exercising the right of search or marking of wares: the Stationers, at whose "hall" must be entered all books for copyright; the Gunmakers, who "prove" all London-made guns; Saddlers, Pewterers, and Plumbers.
III. Companies into which persons carrying on certain occupations are compelled to enter: Apothecaries, Brewers, Builders, etc.
The "halls," as they are called, are for the most part extensive quadrangular buildings with a courtyard in the centre.
The most pretentious, from an architectural point of view, are Goldsmiths' Hall in Foster Lane, and Ironmongers' Hall in Fenchurch Street.
Fishmongers' Hall, at the northwest angle of London Bridge, built in 1831, is a handsome structure after the Greek order, with a fine dining-room. The Merchant Tailors' Hall, in Threadneedle Street, has a wonderful banquet-room, with portraits of most of the Kings of England, since Henry VIII., adorning its walls.
