The Aztec government was made up of four levels. The first level is the family unit. The second level is the calpulli which is made up of a group of families who owned land together. The third level was made up nobles and councils. These nobles and priesthoods provided leadership and had lot of power. The fourth and highest level was held by one person who was considered The Great Speaker, also known as Huey Tlatcani, who led the empire. This system has been compared to the Roman Empire.
The Aztec religion was by far, the most aggressive and gory compared to the Mayan and Inca cultures. They sacrificed thousands of people per year and were preoccupied with the fear of nature and the end of the world. They believed human ritual sacrifices would keep disasters from happening because the gods fed on humans. It was important to keep the sun god alive with sacrifices because if the sun did not rise, the world would end. They did believe that how one died would affect their afterlife.
