"At its height, the Huari Empire dominated almost the entire central Andes and much of the adjacent coastal lowlands. This empire was controlled by the highland city of Huari. In a short time, Huari-derived ceramic styles (themselves influenced by Tiahuanaco wares) appeared in many regions. Early Huari ceramics (like the later Inca wares) tend to occur in politico-religious contexts: in ceremonial centers, cities, and in other high-prestige sites. Molds were used for the mass production of posstery. As these wares spread, local styles began to lose importance.
"The Huari Empire imposed economic, social, and cultural changes on the areas it dominated. Local cultures were disrupted. Major urban centers were established in each valley. Building complexes in the Huari architectural style (administrative structures, storehouses, or barracks) were constructed at various places. Cities rose and fell with the Huari Empire. Goods and information were exchanged across the Andes on a scale never seen before. Various authors have suggested that urbanism and militarism, state distribution of foodstuffs, the Andean road system, and the spread of the Quechua language began with the Huari Empire."
