Tenochtitlan, looking east. From the mural painting at the National Museum of Anthropology, Mexico City. Painted in 1930 by Dr. Atl.

The main contribution of the Aztec rule was a system of communications between the conquered cities. In Mesoamerica, without draft animals for transport (nor, as a result, wheeled vehicles), the roads were designed for travel on foot, just like the Inca and Mayan civilizations. They developed large cities, such as Tenochtitlan, which eventually became Mexico City.
