The Chincha
The growth and expansion of Chimú were paralleled on the southern coast by Chincha, which was a similarly well-organized polity. Comparison between them has been difficult because of the very different evidence available. Whereas Chimú has become familiar through extensive archaeological research, data on the Chincha has come primarily from the study of historical sources.
In the first few years of Spanish rule, the Holy Roman emperor Charles V complained that he had not received any of the newly conquered lands as a personal fief. The conquistador Francisco Pizarro and his brother Gonzalo hurried to assign him three ethnic groups: (1) The Aymara kingdom of the Lupaqa, listed on the Inca quipu at 20,000 households, (2) the tropical island of Puná, in the Gulf of Guayaquil in modern Ecuador, with an unknown aboriginal population, and (3) the coastal Chincha polity, allegedly with 30,000 households. Unfortunately for the Chincha, their population vanished within the first three decades of the Spanish invasion; the royal affiliation and proximity to Lima did not help protect the Chincha.
Belonging to the crown, however, did promote account keeping and administrative reports to the Spanish court. The unusual feature about Chincha was its considerable orientation to the sea. Several thousand households were listed as high-seas fishers and sailors, and thousands more were engaged in long-distance trade with lands to the north. Because the waters off the Chilean and Peruvian coast were cold, there was a long-standing interest in the warm waters off the Ecuadorean coast, more than 1,000 miles away, where the Antarctic current was no longer present. The details of these exchanges are not known, but one feature was paramount in Andean eyes: throughout the central and southern Andes, wherever puna dwellers were the dominant population, there was a demand for the spiny oyster (Spondylus), the shells of which were believed to encourage rainmaking. The one Quechua literary text available lists the spiny oyster as the favourite food of the gods, although it was inedible for humans.
While there has been a long-standing archaeological interest in the shells of this mollusk, the extent and the organization of the shell traffic has not been verified archaeologically. One of the witnesses of the invasion, Pedro Pizarro (a cousin of Francisco), reported being told that the Chincha lord had 100,000 rafts on the “Southern Sea.” The number need not be accurate: even 1,000 oceangoing rafts, with keels and sails, would imply a major economic operation.
Chimú and Chincha have received considerable attention from non-Peruvian scholars; understanding of the contemporaries of these peoples in the highlands, however, has remained sketchy. The oral tradition reported by the early European observers claimed that before the expansion of Tawantinsuyu, the Inca state, there were many polities large and small, all ruled by traditional lords and frequently at war with one another. To what extent the notions of ecological complementarity or the vertical archipelago were attempts to bridge these conflicts or their consequences cannot be stated with any certainty.
The 17th-century Andean writer Felipe Guamán Poma de Ayala (Waman Puma) reported the oral tradition that he had learned from his forebears, who were minor ethnic lords in the Huánuco region. In the century before the Inca conquest people had lived in the “epoch of the soldiers.” During this period
they began to fight and there was much war and death…one lord against the other…bloodshed and taking of prisoners. And they also grabbed their wives and sons and took their fields and irrigation waters and pastures. And they were very cruel and stole each other’s property, cloth, gold, copper, even their millstones.…And so they went and settled on the heights where they built walls and houses inside…and wells to draw water.
Poma de Ayala’s description of Late Intermediate settlement patterns on mountaintops, at the very edge of and even beyond puna cultivation, has been confirmed by field research undertaken near Lake Titicaca by the American archaeologist John Hyslop. He found dozens of walled-in enclosures of 50 to 100 acres and larger. During the Late Horizon—which corresponds to the century of Inca rule—these populations were moved to the lakeshore, along the royal road.
