What is the estimated population of Tenochtitlan at its peak?

At its peak, Tenochtitlan, the capital of the Aztec Empire, is estimated to have had a population of approximately 200,000 inhabitants. This figure reflects the city's status as one of the largest and most advanced urban centers in the world during the early 16th century.

Tenochtitlan was known for its impressive architecture, sophisticated agricultural practices, and complex social organization, all contributing to its ability to support such a large population. The city's location on an island in Lake Texcoco, including its elaborate system of canals and causeways, facilitated trade and resource management, which further augmented its population density.

The evidence from historical sources, including accounts from Spanish conquistadors, supports this estimation, highlighting Tenochtitlan's significance not only in Mesoamerica but also in the broader historical context of urban development.
