The Worshipful Company of Brewers is a livery company of the City of London, ranked 14th in the companies's order of precedence.  Its origins can be traced back with certainty to 1292, although it probably existed in some form up to a century earlier as the Guild of Our Lady and St Thomas Becket.  Its successor, the Mistery of Free Brewers, were granted the right by the Mayor and Aldermen of London to appoint Masters and Wardens in 1406.  Henry VI granted the first of a series of Royal Charters to the company in 1437–38.  Until the last century, the company admitted non-brewers so that they could be represented by a livery company.

The Worshipful Company of Mercers is the premier Livery Company of the City of London and ranks first in the order of precedence of the Companies.  It is the first of the Great Twelve City Livery Companies.  Although of even older origin, the Company was incorporated under a Royal Charter in 1394, the Company's earliest extant Charter.  The Company's aim was to act as a trade association for general merchants, and especially for exporters of wool and importers of velvet, silk and other luxurious fabrics (mercers).  By the 16th century many members of the Company had lost any connection with the original trade.  Today, the Company exists primarily as a charitable institution, supporting a variety of causes.  The Company's motto is "Honor Deo", Latin for "Honour to God". The Worshipful Company of Drapers is one of the 110 livery companies of the City of London.

More usually known simply as the Drapers' Company, it is one of the historic Great Twelve Livery Companies and was founded during the Middle Ages.
