What are examples of a merchant guild?

Merchant guilds were associations of traders and merchants in medieval Europe that regulated trade practices and protected their members' interests. Examples include the Hanseatic League, a powerful alliance of trading cities in Northern Europe, and the Worshipful Company of Fishmongers in London, which specialized in the fish trade. Other notable examples are the Staplers, who controlled the wool trade in England, and the Merchant Adventurers, who facilitated trade between England and continental Europe. These guilds played a crucial role in the economic development and regulation of commerce during their time.
