Merchant guilds were associations of traders and merchants in medieval Europe, formed to protect their economic interests and regulate trade practices. These organizations established rules for fair pricing, quality standards, and the rights of members, helping to ensure a stable marketplace. They also provided support in times of conflict and facilitated networking among merchants. Membership in a merchant guild often required payment of fees and adherence to specific regulations. Guilds played a crucial role in the development of towns and cities, contributing to the growth of commerce and the establishment of trade routes. They were instrumental in shaping the economic landscape of the Middle Ages.
