The Company of Merchants of the Staple of England, the Merchants of the Staple, also known as the Merchant Staplers, is an English company incorporated by Royal Charter in 1319 (and so the oldest mercantile corporation in England) dealing in wool, skins, lead and tin which controlled the export of wool to the continent during the late medieval period. The company of the staple may perhaps trace its ancestry back as far as 1282 or even further.
