The Aztec Empire was located in what is now called central Mexico and was the last of the great Mesoamerica native civilizations to be overthrown. The Aztec Empire was overthrown in 1521 when Hernan Cortes, the Spanish conquistador, defeated the Aztecs at Tenochtitlan.
The Aztecs were the dominant force in the region and were a nomadic tribe that was able to develop a variety of political, religious and social advancements. The Aztecs were able to create a number of crops including beans, squash, tomatoes, potatoes, maize, also known as corn, and avocados. They had an extensive irrigation system that allowed them to build numerous agricultural fields to feed their people. They were also strong hunters and were able to hunt armadillos, rabbits, coyotes, turkeys and snakes as well as fish.
The Aztecs also had a powerful leader and a powerful military. They built a sophisticated city-state of more than 6 million people. The Aztecs built static structures when it came to the various casts of people with nobles at the top and serfs and slaves at the bottom. The Aztec people were interested in furthering themselves intellectually and artistically, so they created a number of sophisticated inventions including the calendar wheels, which consisted of a 365-day solar calendar and a 260-day festival calendar.
