Where was the largest market in the Aztec empire held?

The largest market in the Aztec Empire was held in Tlatelolco, a city adjacent to the capital, Tenochtitlan. This bustling marketplace, known as the "Tianguis de Tlatelolco," was a vital economic hub where thousands of merchants traded a wide variety of goods, including food, textiles, and crafts. It served not only as a center for commerce but also as a social and cultural gathering place for the Aztec people.
