Ñançen Pinco is believed to have conquered the coast from the Saña River, just south of Lambayeque, south to Santa. After him came six rulers before Minchançaman, who conquered the remainder of the coast from at least as far north as Piura and possibly to Tumbes, south almost to Lima. His triumph was short-lived since he himself was conquered by the Inca in the early 1460s.

There were other cities at Farfán and Pacatnamú in the Pacasmayo Valley and at Purgatorio and Apurlé in the Leche and Motupe valleys, respectively, which shared some features with Chan Chan. All included large walled compounds. Apart from the cities, there were defensive settlements, such as one in the narrow part of the Moche Valley, up which it straggled for five miles, occupying terraced hillsides and side valleys and commanding three of the main canals. A third type of settlement consisted of scattered compounds in the midst of large irrigated areas, one example of which was found in the Chicama Valley alongside an irrigation canal that took water to Chan Chan. Chan Chan covered an area of about 14 square miles (36 square km), with a central area of about 2.5 square miles containing 10 or more large rectangular enclosures sometimes called ciudadelas (“citadels”). These were surrounded by tapering adobe walls, 10 feet thick at the base and about 30 feet high. They ranged in size from about 400 by 200 yards to 650 by 400 yards.
At least six of these citadels have similar plans, and one has been studied in detail. It has a narrow opening at the north end and is divided into three parts by high walls. The northern part contains a large entry court, flanked by a kitchen area and several smaller courts, leading to a densely built area of small courts, some of which have a U-shaped structure at one end, while others are filled with small rooms. The U-shaped structures, which do not appear to have been roofed, may have been shrines, and the courts that contain them may have had walls covered with mud-plaster reliefs, such as bands of animals, birds, or fish, scrolls, or step frets, arranged in a manner reminiscent of Chimú textiles. The central part has a somewhat smaller entrance court leading to several courts occupied by rooms, perhaps storerooms, although nothing was found in them. Another feature of this area is a great burial platform with rows of chambers arranged in three levels. All these features are connected by narrow and tortuous passages. The southern part is an open area, containing one or more pukíos (rectangular areas where the ground has been lowered to the water table, either to supply water or to grow plants). In the spaces between the enclosures, and elsewhere in the city, are large areas of dwellings, irrigated areas, and cemeteries.

It is now thought that the ciudadelas may have been the dwellings of the ruling classes and their immediate retainers, and it has even been suggested that they were the palaces of successive rulers, maintained by their descendants in the way that those of deceased Inca were maintained in Cuzco. The number of recognizable ciudadelas agrees with the number (10) of known Chimú rulers. This intriguing suggestion is further supported by the belief that the Inca learned a great deal from the Chimú after they conquered them, for, not content with carrying Minchançaman off to Cuzco, they established a colony of north-coast workmen there, and Topa Inca Yupanqui (Thupa ’Inka Yupanki) appears to have worked out the political organization of the empire at the same time, basing it largely on the Chimú system.
Roads between the valleys were always necessary to coastal states and were vital to the Chimú, and the Inca may have learned something in this connection also. There are almost continuous traces of a road from just north of Lambayeque to the Chao Valley just south of Virú, with remains even farther south in Santa, Nepeña, and Casma. The remains differ in elaboration and tend to be wider and more imposing near the cities; in the deserts between valleys they were tracks marked by posts or bordered by low walls, but in the valleys the simplest type is a leveled surface 15 to 25 feet wide, with walls of stone or adobe about three feet high and with the surface of the road sometimes being raised.
Although the Chimú had a powerful, aggressive, organized state, their dependence on elaborate irrigation systems for the maintenance of concentrated populations rendered them vulnerable to attack, which was one of the main factors that enabled the Inca to take them over comparatively easily. Geoffrey H.S. Bushnell John V. Murra 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.
