The physical environment of the region where the Aztecs established their empire, particularly the Valley of Mexico, played a crucial role in their development and expansion. One key example is the availability of fertile land and the proximity to water sources, particularly Lake Texcoco.
The lake provided not only a means for transportation and trade but also supported agriculture through the use of chinampas, which were floating gardens created by the Aztecs. This agricultural innovation allowed them to produce abundant food supplies, which sustained a growing population and supported the expansion of their empire.
Additionally, the central location in Mesoamerica facilitated trade and military conquests, enabling the Aztecs to control trade routes and gain access to resources from distant regions. The geography also presented natural defenses against outsiders, contributing to their ability to consolidate power and maintain control over vast territories.
Overall, the combination of fertile land, water resources, and strategic location allowed the Aztecs to thrive and expand their empire effectively.
