The earliest mention of Craft Gilds is in the reign of Henry I., when notice is found of the Weavers of London, Oxford, Winchester, Lincoln and Huntingdon, the Cordwainers of Oxford and the Fullers of Winchester[61]. They became more common and more influential as the development of industry was fostered by the central government. This was especially the policy of Edward I. and Edward III. By the end of the 14th century the Craft Gilds become numerous. As they took over the duties and functions of the Merchant Gild the existence of the latter was rendered to a considerable extent superfluous, and the merging of the Gilda Mercatoria into the Communa became not only inevitable but convenient and natural. During the 14th and 15th centuries, when the Craft Gilds attained their highest power, the decay of the Merchant Gilds became very marked. [Sidenote: _The later "Merchant Gild."_] In some places where this happened the name of the Merchant Gild wholly disappeared. In others where the expression continued in use the institution changed its character and became simply a religious fraternity. In a few instances the select corporation alone inherited the name: in some the whole body of freemen did so. Again, there are examples of a survival of the expression as applied to the whole body of tradesmen, that is the whole of the members of the various Gilds[62]. A Patent of Queen Elizabeth, dated 1586, thus alludes to the aggregate of unions under the collective name of "the Gild of Burgesses of Shrewsbury." In the same way we read of "the several companies belonging to the guild merchant of Reading," "the Guild of Merchants in Andever, which Guild is divided into three several Fellowships," etc. Just as the Merchant Gild differentiated itself into Craft Gilds, the Craft Gilds afterwards again in the aggregate took the name and style of the Merchant Gild.
