Guild
A guild was an association of craftsmen or merchants in medieval and early modern Europe that regulated the production and sale of specific goods or services within a locality, typically enforcing entry barriers, quality controls, and pricing to benefit members.[1][2] These organizations emerged around the 11th-12th centuries amid urban growth, evolving from earlier fraternal or religious groups into powerful economic entities that controlled apprenticeships—often requiring seven years of unpaid labor under a master—journeyman phases, and mastery exams to limit competition and ensure skill transmission.[3][4] Guilds provided mutual aid, such as funerals and dispute resolution, and wielded political influence by negotiating with rulers for monopolies, but their exclusionary practices—barring women, immigrants, and the poor—along with output restrictions and innovation suppression, often elevated prices and hindered broader economic efficiency.[5][6] Economists have documented how these cartels prioritized rent-seeking over consumer welfare, contributing to their decline with the rise of markets and state centralization by the 18th-19th centuries.[4][7]
