The Aztec and Inca civilizations were different in their public works projects because the Aztecs focused on agricultural innovations, while the Incas focused on road construction.
The Aztecs were a pre-Columbian Mesoamerican people of Central Mexico in the 14th, 15th, and 16th centuries. They adopted an agricultural system of farming which was known as "Chinampas".
The Incas who were American Indian people, constituted originally a small tribe in the southern highlands of Peru. This tribe focused on building a strong road system.
