Toltec Pyramid of the Warriors

The Toltecs (or Toltec or Tolteca) were a Pre-Columbian Native American people who dominated much of central Mexico between the 10th and 12th century AD. Their language, Nahuatl, was also spoken by the Aztecs.

They originated as a militaristic nomadic people, and they or their ancestors may have sacked the city of Teotihuacan (ca. 750). After they established a more settled existence, the Toltec fused the many small states in Central Mexico into an empire ruled from their capital, Tula (also known as Tollan, or Tolan). They were accomplished temple builders. Their influence spread through much of Mesoamerica in the Post-Classic era of Mesoamerican chronology. The Toltec influence on the Post-Classic Maya of Yucatan is heavy, especially evident at the city of Chichen Itza. Their pottery has been found as far south as Costa Rica.
Some writers have alleged that the Toltecs introduced the cult of Quetzalcoatl, the plumed serpent. This is certainly not so, as this deity was commonly depicted throughout Mesoamerica for centuries earlier, going back to Olmec times. In Toltec (and later Aztec) mythology Quetzalcoatl was a rival of Tezcatlipoca, the first deity who is known to have demanded human hearts as sacrifice. Thus the Toltecs seem to have introduced the habit of mass human sacrifice as later practiced by the Aztecs.
The Toltec empire is believed to have been destroyed around 1200 AD by the nomadic warriors of the Chichimecs. The ruling family of the Aztecs claimed to descend from Toltec ancestry via the sacred city of Colhuacan.
