Quetzalcoatl:
According to a Toltec legend, their civilization (which dominated Central Mexico from approximately 900-1150 A.D.) was founded by a great hero, Ce Acatl Topiltzín Quetzalcoatl. According to Toltec and Maya accounts, Ce Acatl Topiltzín Quetzalcoatl lived in Tula for a while before a dispute with the warrior class over human sacrifice led to his departure. He headed east, eventually settling in Chichen Itza. The God Quetzalcoatl definitely has a link of some sort to this hero. It may be that the historical Ce Acatl Topiltzín Quetzalcoatl was deified into Quetzalcoatl the god, or he may have assumed the mantle of an already existing divine entity.

Huitzilopochtli:
Huitzilopochtli was one of the most important of the Aztec gods, the god of the sun, warfare, military conquest and sacrifice, who according to tradition, led the Mexica people from Aztlan, their mythical homeland, into Central Mexico. According to some scholars, Huitzilopochtli could have been a historical figure, probably a priest, who was transformed into a god after his death.
