Thieves' guild

In popular fiction, a thieves' guild is the concept of a formal association of criminals who participate in theft-related organized crime. The trope has been explored in literature, cinema, comic books, and gaming, such as in the Fafhrd and the Gray Mouser story "Thieves' House" by Fritz Leiber and the role-playing game Dungeons & Dragons. Though these more modern works are fictitious, the concept is inspired by real-world examples from history, such as Jonathan Wild and his gang of thieves.

Literary antecedents
Some stories of One Thousand and One Nights celebrated artful thieves and criminal brotherhoods with a hierarchy and code of honor. The Sandalwood Merchant and the Sharpers features an old man known as the "Sheikh of Thieves" who delivered judgement on less experienced sharpers. This was based on actual thieves' guilds in Cairo in the Ottoman period, that were known to return stolen goods for a price, and which were managed by a sheikh. These survived up until the 19th century, and were mentioned by Edward William Lane in the 1830s.

A central feature of Miguel de Cervantes' story Rinconete y Cortadillo, set in sixteenth-century Seville, is the city's strong and well-organized thieves' guild built to the model of the medieval guild. As in any other profession, a young thief must start as an apprentice and slowly work his way to become a master craftsman—in this case, a master thief. No one could come into a city and start on a career as a thief without belonging to the local guild (as Cervantes' protagonists soon find out), which would have been in many cases true also for a medieval tailor or carpenter wandering into a strange city. Thieves also have their own church where they go to pray (shared with prostitutes).
