The Aztecs were not simple village people, but occupied a large City-State much like Greece and Rome.  Like Egypt they used funerary jars and mummification, they built Pyramids;  and had scientific knowledge well beyond their time.  They created astronomical Calendar systems  that is still unsurpassed.  And; their  rulers were the living embodiment of their Gods; and carried with them; not only the hand of the  Law; but the forces of nature and the will of God. The Three main Gods of the Aztec are:  HUITZILOPOCHTLI* , TLALOC*  and  QUETZALCOATL*.  I will have more details about each of them and the Aztec Human Sacrifice;  following the list of all of the Aztec Gods that I could find.

After defeating the Four Hundred Stars, Huitzilopochtli slew his sister and cast her down the hill at Templo Mayor where her body broke to pieces on striking the bottom. Priests at Templo Mayor killed prisoners in the same way, these sacrifices being replicas of mythical events designed to keep the daily battle between day and night and the birth of the God of War ever in the minds of the people.

Souls who win no merit in life come here after death, but they do not suffer as in the Christian hell. Instead they merely endure a rather drab and colorless existence before passing again into the world of the living.

HUITZILOPOCHTLI* God of the SUN and War-Lord of the South.  He was the young Warrior Lord of the Day. Important Gods of the Aztecs are often represented by  Birds; who fly free to the heavens.  All have been shown as an Eagle. Huitzilopochtli was particularly  represented by the  "The Blue Heron Bird", sometimes seen as a colorful  Macaw".  The derivation of his name may have come from the ancient Chichimeca "Tetzauhteotl", possibly meaning "Omen-God" Huitzilopochtli's creation may also  have come from the ancient Mexica god "Opochtli", the Left Handed One, and a leading old Chichimec god of weapons and water. He was called "He Who Divides the Waters", and was principal in worship in the Huitzilopochco area and it's famous waters. Opochtli is thought to have been worshipped in ancient Aztlan (ancient Mexico). He is considered an incarnation of the sun and struggles with the forces of night to keep mankind alive. Only to have found a place of major worship among the Aztec peoples. Huitzilopochtli is credited with inducing the Aztecs to migrate from their homeland in "Aztlan" and begin the long wanderings which brought their tribe to the Mexico Valley. Huitzilopochtli  was carried during the wandering years by four God "bearers" and he is represented as a combination hummingbird and serpent tail being carried seated on a blue wooden bench in the form of a liter. The liter poles contained images of serpents long enough to be carried on the shoulder of men. Huitzilopochtli is said to be a representation of Tezcatlipoca in midsummer as the high sun in the southern sky. His name may have derived with his association with the color blue as when staring at the sun, spots of blue are seen by the eyes after looking away. His association with "on the left", was because when facing in the direction of the sun's path, east to west, the sun passed on the left. He resides in the seventh heaven of Aztec mythology. The seventh heaven is represented as blue. According to Aztec legend, Coatlicue, goddess of the earth had given birth to the moon and stars. The moon, Coyolxauhqui, and the stars called, Centzonhuitznahuac, became jealous of Coatlicue's pregnancy with Huitzilopochtli. During his birth, Huitzilopochtli used the "serpent of fire" and the sun's rays to defeat the moon and stars. Every day the battle continues between day and night. The people saw the sunrise as a daily victory for this deity over the forces of darkness. Huitzilopochtli can only be fed by Chalchihuatl, or the blood of sacrifice, to sustain him in his daily battle. His temple on the great Pyramid in Tenochtitlan was called Lihuicatl Xoxouqui, or "Blue Heaven" was the focus of fearsome sacrifices of prisoners captured by Aztec warriors. Victims' heads were strung as trophies on a great rack, the Tzompantli, erected in the precinct below.  Over 20,000 victims are thought to have been ritually killed at the opening of his great temple during a four day period.

Note: The Aztec language is a phoenetic language and there may be various different spellings for the same God. I also  suspect that a few of the names have either been made up by someone or are mis-spelled.
