Tezcatlipoca or Tezcatl Ipoca was a central deity in Aztec religion. He is associated with a variety of concepts, including the night sky, hurricanes, obsidian, and conflict. He was considered one of the four sons of Ometecuhtli and Omecihuatl, the primordial dual deity. His main festival was Toxcatl, which, like most religious festivals of Aztec culture, involved human sacrifice.

The Aztec religion is a polytheistic and monistic pantheism in which the Nahua concept of teotl was construed as the supreme god Ometeotl, as well as a diverse pantheon of lesser gods and manifestations of nature. The popular religion tended to embrace the mythological and polytheistic aspects, and the Aztec Empire's state religion sponsored both the monism of the upper classes and the popular heterodoxies.
