Mercery (from French mercerie, meaning "haberdashery" or goods, or "haberdashery"—a shop trading in textiles and notions) initially referred to silk, linen and fustian textiles among various other piece goods imported to England in the 12th century. Eventually, the term evolved to refer to a merchant or trader of textile goods, especially imported textile goods, particularly in England. A merchant would be known as a mercer, and the profession as mercery.
The occupation of mercery has a rich and complex history dating back over 1,000 years in what is now the United Kingdom. London was the major trade centre in England for silk during the Middle Ages, and the trade enjoyed a special position in the economy amongst the wealthy.
