In short: In the 12th century, 'mercery' was a luxury trade of silk and linen. But after the devastating Black Death, these merchants didn't just survive; they weaponized the economic vacuum to build a massive monopoly, transforming from simple traders into a powerful aristocratic class.

The term 'mercery' originated in the 11th century as an amorphous trade involving everything from needles to silk. By the 12th century, it became a distinct occupation in England, specifically for high-quality imported goods like silk, linen, and fustian—a Middle Eastern cloth of flax and cotton. While the masses wore simple wool or linen, mercers catered to the wealthy, selling dress accessories, bedding, and luxury headwear like wimples and coifs. These businesses were often family-run units where the husband handled marketing while the wife managed the workshop, buying stock and training apprentices.

The trade reached a turning point following the Black Death in 1394. While the plague killed over a third of the Livery Company for general merchants, the survivors thrived in the subsequent economic revival. With a smaller population, wages rose and farmers shifted toward livestock and specialty crops, improving general living standards. This created a new market of 'ordinary' people who could finally afford higher-quality clothing. The mercers capitalized on this by expanding their reach into provincial towns, establishing a complex market system that bridged the gap between the lower and upper-middle classes.

By the 15th century, the Worshipful Company of Mercers dominated the market, controlling at least 30% of London's cloth exports. They maintained power by strictly monopolizing the trade of silk and linen, often displacing independent merchants. However, this success led to a downfall in the late 16th century. By neglecting the common artisan and focusing only on elite luxuries, the Company allowed independent retailers to undercut them. Their failure to adapt to the needs of the broader market eventually eroded their once-absolute control over the English textile trade.

The designation 'mercer' has mostly vanished from modern trade, remaining chiefly within the title of the Worshipful Company of Mercers, which ranks first among the City of London's twelve Great Livery Companies.
