What happened
The pochteca were a hereditary class of professional merchants who traded over long distances for the Aztec state, specializing in precious goods unavailable in the Valley of Mexico: tropical bird feathers, gold, turquoise, shells, greenstone, cacao beans, and exotic animal skins, according to World History Encyclopedia's account of Aztec society. They were supervised by the most experienced traders among them, the pochtecatlatoque, who administered trade and settled disputes among merchants in their own dedicated courts, and a related group called the tlaltlani traded specifically in slaves destined for sacrifice, a role that brought them particular wealth and privilege. Because pochteca traveled constantly beyond the empire's formal borders to reach distant markets, they were also positioned to bring back political and military information about the peoples they traded with, a secondary function noted across multiple accounts of the class. Their commercial hub inside the capital was the market at Tlatelolco, Tenochtitlan's twin city built on the same island, which World History Encyclopedia's description of Tenochtitlan notes sold goods brought in from all corners of Mesoamerica.
Why it matters
The pochteca and the Tlatelolco market gave the Aztec Empire an economic reach well beyond what its armies alone controlled, moving goods and information across a wider Mesoamerican world that included regions the Triple Alliance never conquered. Their dual role as traders and intelligence gatherers also meant that Tenochtitlan usually had advance warning of political developments elsewhere, including, later, reports of the first Spanish ships along the coast.
How we know
The scale and organization of the Tlatelolco market is described directly by Spanish conquistadors who visited it in 1519, among them Bernal Diaz del Castillo, whose eyewitness account is corroborated by continuing archaeological work at the Tlatelolco site.
