The Royal Charter of Incorporation of the Company of Merchant Taylors of the City of York was issued by King Charles II on 26th April 1662, but the company traces its origins back to the three medieval guilds of tailors, drapers and hosiers. Although tailors appear in the City's Freemen from 1273, the earliest references to guild organisation are the ordinances and register of members dating from 1387 and entered in the city's memorandum book among the City Archives.
