Wari

← Encyclopedia

Twenty-five kilometers north of the modern city of Ayacucho, at twenty-eight hundred meters in the dry highlands of south-central Peru, the ground holds the wreck of a city that once covered some fifteen square kilometers. Its walls run in long straight courses, gray and roofless now, enclosing rooms upon rooms in tight rectangular cells. At its height, perhaps forty thousand people lived among those compounds. The Andean peoples who came after did not keep its name; archaeologists who began excavating in the 1940s borrowed the modern place-name and called the city, and the empire that radiated from it, Wari. For roughly four centuries — from about 600 to 1000 CE — that empire was the dominant power of the central Andean highlands, and the period it shares with its southern rival is named for the two of them together: the Middle Horizon.

The horizon and its name

Andean prehistory is conventionally divided into long spans of regional variety (the Intermediate Periods) broken by shorter spans when a single art style, a single religious vocabulary, spreads across enormous distances. These unifying spans are the Horizons. The Early Horizon belongs to Chavín; the Late Horizon belongs to the Inca. Between them lies the Middle Horizon, c. 600–1000 CE, defined by the near-simultaneous expansion of two highland states sharing a common iconography of staff-bearing deities: Wari in the north, ruling much of what is now Peru from the Ayacucho Basin, and Tiwanaku in the south, ruling the Lake Titicaca basin of Bolivia. They were peers, not one polity — two centers, two capitals, two distinct ceramic and architectural traditions — and their direct frontier touched at only a single well-documented point, far to the south in the Moquegua Valley. To collapse them into one is to lose the central drama of the period: two imperial experiments, drawing on the same religious imagery, working the same vertical landscape, and never quite meeting.

What made Wari recognizable as an empire was not conquest narrative — there are no inscriptions, no king-lists, no annals — but a built signature repeated across the map. Wherever Wari authority reached, a particular kind of architecture appears: large rectangular enclosures of high fieldstone-and-mortar walls, subdivided into repetitive modular rooms and patio groups along an orthogonal grid. The plan is administrative in the most literal sense: a template imposed on terrain regardless of what stood there before. Reading those compounds, their placement, and the roads between them is how the empire is reconstructed.

The capital

The capital — also called Wari, or Huari — was first settled around 250 CE and grew through the Middle Horizon into a sprawling, walled metropolis. Its oldest quarter, Vegachayoq Moqo, holds the remains of what excavators identify as a palace; elsewhere rise high-walled compounds, semi-subterranean galleries built of finely fitted stone, mortuary structures, and dense residential cells stacked in places to two or three stories. The masonry is utilitarian rather than ornamental — long rough walls plastered and once painted, not the polished ashlar the Inca would later make famous — but the scale is unmistakably urban, and the planning unmistakably deliberate. This was a center that consumed the surplus of a wide territory and projected order back out across it.

Near the capital, at Conchopata, a community of potters produced the empire’s most charged objects: oversized ceremonial urns and face-neck jars painted with the staff-bearing deities and their winged attendants. These vessels were not for daily use. Many were ritually smashed and buried in caches, or broken across the floors of buildings as those buildings were sealed and abandoned — deposits that mark a structure’s closing as a sacred act. Conchopata also yielded the form that became the diagnostic temple of the whole civilization: the D-shaped precinct, a curved-back ceremonial enclosure that recurs from the heartland to the provinces and that anchored the empire’s religious life.

The administrative network

Wari governed through a string of planned installations set down across the central Andes, each a variation on the enclosure-compound template. The largest and best understood lie at the empire’s edges and along its arteries.

Pikillacta, south of Cuzco — the second-largest Wari complex known — was occupied between about 600 and 900 CE and raised in three successive construction phases, the last left unfinished when the site was abandoned. Its plan is a severe grid: four sectors of densely packed rooms and two zones of large open enclosures, with gypsum-plastered floors and walls, plaster-lined niches, plastered staircases, and sub-floor offering pits. Multistory collapse in the rubble shows the rooms once rose in tiers. Beneath the floors near a ceremonial area, excavators recovered caches of forty miniature turquoise figurines apiece — clothed males and females whose distinct headgear and garments seem to encode rank and identity, deposited as offerings alongside Spondylus shell. Pikillacta was less a town than a machine for administration and ceremony, built and abandoned to a single imperial logic.

Far to the south, on a sheer mesa above the Moquegua Valley, Cerro Baul marks the one place where Wari and Tiwanaku stood at arm’s length. Wari colonists established the hilltop colony around 600 CE, fortifying a position within reach of Tiwanaku’s own settlers in the same valley — the single archaeologically clear point of contact between the two great powers. On the summit the colonists built a brewery capable of producing chicha de molle, a maize beer flavored with pepperberry, in large batches. When the colony was finally given up, late in the empire’s life, it was not simply walked away from. The inhabitants staged a closing feast — brewing, drinking, smashing the vessels, and burning the brewery down — a deliberate ceremonial evacuation rather than a flight, documented in the study of the site that takes its title from the act: Burning down the brewery.

Other centers fill out the network: Viracochapampa in the northern highlands, left unfinished; Jincamocco commanding routes to the south; Honco Pampa; Azangaro near the heartland; and the great coastal oracle of Pachacamac, whose pilgrimage cult Wari patronized and helped broadcast. The placement of these installations was not uniform. The archaeologist Katharina Schreiber, whose 1992 study Wari Imperialism in Middle Horizon Peru framed the modern picture, described the result as a mosaic of control: in some valleys Wari built large centers and ruled directly; in others, where local polities were already complex, it ruled lightly, through alliance and indirect leverage, leaving a thinner footprint. The empire was not a single uniform grid stamped on the land but a patchwork of arrangements suited to each province.

Roads, storehouses, and the knotted cords

Binding the network together was a road system threading the highlands and dropping to the coast, with way-stations and storehouses set along it. The storehouses, ancestors of the structures the Inca would call qollqa, were sited and built to preserve surplus — maize, tubers, freeze-dried foods — against the lean season and the demands of the state. The principle is the one that would later organize the largest empire of the pre-Columbian Americas: a polity that moves goods and labor across vertical ecological zones, storing the produce of many altitudes and redistributing it as administration requires.

So too with record-keeping. The earliest known khipu — bundles of knotted cords used to hold quantitative information — come from Wari contexts, and they differ from the later Inca examples in their structure: Middle Horizon cords cluster their knots in groups of five, suggesting a base-five reckoning, where the Inca khipu later resolved into a strict decimal place-value system. The medium itself, the idea of fixing accounts and perhaps narrative in spun and knotted fiber, belongs to Wari before it belongs to the Inca. When the Inca built their road, their granaries, and their knotted archive five centuries on, they were scaling a template the highland Andes had already learned.

The architecture of belief

The religious image that traveled with Wari is the Front-Face, or Staff, deity — a frontal figure standing rigid, a vertical staff gripped in each hand, the head crowned with radiating rays that end in animal heads, the face mask-like and severe. It is the same figure carved at the center of the Gateway of the Sun at Tiwanaku, where rays fan from the head, and it descends from a far older Andean lineage: the term was first applied by John Rowe to the principal figure of the Raimondi Stele at Chavín de Huántar, and the staff-bearing god can be traced through the Titicaca-basin traditions that fed Tiwanaku. Wari carried this deity north and worked it across its own media — onto the oversized Conchopata urns, into the dense weave of its finest tunics, around the curved walls of its D-shaped temples. To follow the image is to watch a religious idea become a political instrument: as the staff god spread on Wari pottery and cloth, it became a mark of allegiance to the highland power, a shared visual creed binding distant provinces to the Ayacucho center.

The D-shaped temple is that creed in stone. Its curved rear wall and flat front enclose a single ceremonial space, repeated with remarkable consistency from the capital to the colonies — a standardized house for a standardized cult, the architectural counterpart to the standardized enclosure-compound. What was enacted within belongs to the inner life of the tradition and is not recoverable as instruction; what survives is the architecture of the belief — the form built to hold it, the vessels broken to close it, the figurines buried to consecrate it.

The most refined surviving expression of Wari art is textile. The empire’s tapestry tunics, the most prestigious garments it produced, were woven from astonishing lengths of handspun camelid yarn — alpaca fiber measured by the mile in a single garment — and bear figurative designs of profile attendants, winged felines, and staff-bearing figures, often deliberately compressed and abstracted across the cloth. They differ sharply from the spare geometric tunics of the later Inca; where the Inca standardized, Wari elaborated. A surviving example, examined in Smarthistory’s account of a Wari tunic, shows the staff deity’s attendants dissolved almost to pattern, the religious figure carried not as portrait but as woven sign of office and order.

The reach and the debate

How much of Peru Wari actually governed, and by what means, is the live argument of Andean archaeology, and the evidence pulls in two directions at once. On one reading, Wari was a true territorial empire: its centers were garrisons and capitals, its roads were instruments of control, its iconography was state propaganda. On another, the spread of Wari styles owes as much to a shared Middle Horizon religion and to trade in fine goods as to political domination, and the “empire” was a looser thing — a network of influence, alliance, and pilgrimage. Genetic studies of populations on the central coast have found surprisingly little Wari demographic imprint, complicating any picture of mass colonization there. The evidence supports neither pure conquest nor pure cult: it supports Schreiber’s mosaic, varying province by province, dense at the strategic centers and thin at the margins. Wari is best read on its own terms, as a specifically Andean solution to the problem of governing vertical space.

This is, plainly, an archaeological reconstruction, not a recovered chronicle, and it is the opposite of the lost-civilization fantasy: Wari is a real, datable, excavated highland state, the product of indigenous Andean ingenuity, ancestral to the Quechua-speaking peoples who still inhabit these mountains. The story it tells is one of administration, not of vanished super-science.

The decline

Around 1000 CE the system came apart. A prolonged drought gripped the central Andes, straining the agricultural surplus on which the storehouses and the centers depended; political fracture compounded the strain, or was deepened by it. Across the empire, settlements that had taken generations to build were abandoned, and the abandonment was not always orderly — fractured floors and burned, destroyed precincts mark a violent unmaking in many places, while Cerro Baul’s brewers chose instead to close their colony with a last deliberate feast and a fire of their own setting. The capital emptied. What followed was the Late Intermediate Period, a long interval of regional kingdoms and renewed local variety, with no single highland power to replace the one that had fallen.

The coast did not stand still while the highlands fragmented. To the south, the Nazca lines and ceremonial landscape had preceded the Middle Horizon and were drawn into Wari’s orbit at its height; to the north, the great kingdom of Chimor would rise on the desert littoral in the centuries after Wari’s fall, building its own vast adobe capital. What Wari had assembled in the highlands and then let go was an entire working grammar of empire: the planned enclosure-center, the long road with granaries set along it, the surplus stored against the lean year, the account kept in knotted cord, the staff deity carried province to province as the sign of one order. That grammar was not invented again from nothing. When a later highland power gathered it up and stretched it across the whole spine of the Andes, from Ecuador to Chile, the Inca were re-cutting a pattern first laid into the dry ground above Ayacucho — the enclosure, the road, the storehouse, and the god, in the same order Wari had set them.
