The Huari empire also served as a model for the following Inca Empire. They already had a major road network set up throughout their empire which served as an example to the mighty Inca empire. Also they had large religious centres sush as Pachacamac as a counterpart for Tihuanaco.
The oldest primitive cultures appeared in 6000 BCE: in the coast (in the provinces of Chilca and Paracas) and in the highlands (in the province of Callejon de Huaylas).
Tiahuanaco culture was developed by the borders of lake Titicaca between IX and XIII centuries.
This culture built the city of Chan Chan in the valley of the Moche river, in La Libertad, between the XIV and XV centuries.
After conquering another people, as in most conquests, the Wari subdued the old cultures and enforced their own way of life forbidding any practice of the former culture, losing all traces of the unwritten culture that was conquered.
Wari cities were made up of large rectangular shaped buildings that were laid out in strict grid patterns that would resemble most of today's city block structures.
This caused the Wari to flee to the lower jungles of the Andes.
