Pochteca (singular pochtecatl) were professional, long-distance traveling merchants in the Aztec Empire. They were a small, but important class as they not only facilitated commerce, but also communicated vital information across the empire and beyond its borders. The trade or commerce was referred to as pochtecayotl. The pochteca also traveled outside the empire to trade with neighboring lands throughout Mesoamerica. Because of their extensive travel and knowledge of the empire, pochteca were often employed as spies.
Pochteca occupied a high status in Aztec society, below the noble class. The pochteca were responsible for providing the materials that the noble class used to display their wealth. These materials were often obtained from foreign sources. The pochteca also acted as agents for the nobility by selling the surplus tribute that had been bestowed on the noble and warrior elite. The pochteca traded the excess tribute (food, garments, feathers and slaves) in the marketplace or carried it to other areas to exchange for trade goods.
Due to the success of the pochteca, many of these merchants became as wealthy as the noble class, but were obligated to hide this wealth from the public. Trading expeditions often left their districts late in the evening, and their wealth was only revealed within their private guildhalls. Although politically and economically powerful, the pochteca strove to avoid undue attention. The merchants followed their own laws in their own calpulli, venerating their god, Yacatecuhtli, "The Lord Who Guides", an aspect of Quetzalcoatl. Eventually the merchants were elevated to the rank of the warriors of the military orders.
The pochteca were organised into twelve guilds, each based in one of the urban centers of the Valley of México:
The markets were part of a complex interlocking system. In the Valley there were four levels of market:
Some of the cities were famous for specialized markets:
The highest official of the pochteca in Tenochtitlán was the Pochtecatlailotlac, the Merchant-Arbiter who also sat as one of the judges in the Tlacxitlan, the highest court of law.
