The master and wardens superintended the taking of apprentices by their members, searching the weights and measures of shopkeepers belonging to the Company, and otherwise regulating their commercial dealings. The Company appointed brokers of mercery wares, under the first charter to the City by Edward II., by which it was declared that there should be no brokers in the City but those chosen by the merchants in the mysteries in which they exercised their office, and under the charter of Edward III., which declared that none should exercise the office of broker in foreign merchandise in London unless chosen by the merchants of the mysteries in which they should act. The Company also appointed a common meter of linen cloth and silk, a common weigher of raw silk, and tackle porters to do their work at the waterside. The Company no longer appoint to any of these offices, because of the different methods of carrying on business which have obtained in modern times.

In the 13th year of Edward II. the Companies had advanced towards the phase of “Livery Companies.” “Moultz des gens de Mesters en Loundres furent vestus de suite.

The Company seem to have exercised some supervision over the retailers of silk and other mercery wares previous to the reign of Queen Elizabeth; but such supervision was probably not founded on any legal basis, as a petition to the privy council at the commencement of that queen’s reign, praying that these rights should be recognised, was unsuccessful.

The numbers of the Company have been recruited by the admission of apprentices, and from the sons of mercers, who have from very early times been always entitled to the freedom; and one reason for the smallness of the Company may probably have been the old custom, established so long ago as 1347, that no strangers should be admitted to the freedom without the consent of the generality. The Company has never been very numerous. In 1347, when it was refounded, 103 persons paid their entrance fees; in 1527 the Company numbered 144; in 1707, when most numerous, 331; and on December 31, 1880, 166.

The earliest date of which there is a record in the Company’s books is the year 1347, when it was reorganised, if not refounded.

The statement that no one should take as an apprentice one who had carried packs through the country, called pedlars, seems to show that a mercer at this time had ceased to be, if he had ever been, a pedlar.

Previous to the charter granted by Richard II., the mercers did not pretend to be a corporation, but simply a member of the City. In their petition to Parliament in 10th Richard II., against Nicholas Brembre, then mayor, they call themselves “the folk of the mercerie, a member of the city.” The Company, having at this time no hall of their own, assembled either in the house of one of the wardens, or in the hall or church of the hospital of St. Thomas of Acon, the site of which is now occupied by their chapel and hall, and subsequently occasionally at the Prince’s Wardrobe in the Old Jewry. They had then no landed property, and their income was derived from subscriptions, apprentice fees, and fines, and amounted to about £20 a year.

The Company’s first charter, enrolled at the Record Office (the original of which has been lost), is dated at Westminster the 13th January, 17th Richard II. (1393).

The most important event in the early history of the Mercers Company was the appointment of the Company as trustees of the charities of Sir Richard Whittington, several times master or principal warden of the Company, and four times Lord Mayor of London. He died in the year 1422-23. It is not necessary to enumerate precisely the munificent works of charity which were carried out by Sir Richard Whittington in his lifetime, or by his executors after his death; suffice it to say that he, or they by his direction, rebuilt the parish church of St. Michael Royal, rebuilt the prison of Newgate, built or repaired the City conduits, contributed very largely to the building of St. Bartholomew’s Hospital and of the Guildhall, to the library of the Corporation of London, and the library of the Greyfriars, and established a chaplain at St. Paul’s. Whittington appointed John Coventry, John White, John Carpenter, and William Grove to be executors of his will, which was proved in March 1422-23. On the 12th November, 3rd Henry VI. (1424), his executors obtained a charter from the King to found Whittington college and almshouses. Of both these foundations the Mercers Company were made trustees.

The Company’s second charter was granted by Henry VI. at the prayer of the executors of Whittington.
