political power at Chan Chan is demonstrated by the organization of labor to construct the Chimú's canals and irrigated fields. Chan Chan was the top of the Chimu hierarchy, with Farfán in the Jequetepeque Valley as a subordinate. This organization, which was quickly established during the conquest of the Jequetepeque Valley, suggests the Chimú established the hierarchy during the early stages of their expansion. The existing elite at peripheral locations, such as the Jequetepeque Valley and other centers of power, were incorporated into the Chimú government on lower levels of the hierarchy. These lower-order centers managed land, water, and labor, while the higher-order centers either moved the resources to Chan Chan or carried out other administrative decisions. Rural sites were used as engineering headquarters, while the canals were being built; later they operated as maintenance sites. The numerous broken bowls found at Quebrada del Oso support this theory, as the bowls were probably used to feed the large workforce that built and maintained that section of canal. The workers were probably fed and housed at state expense. Cultural and Economic Exchange The Chimú's vast territorial expansion increased the amount of cultural identities within the civilization.They also incorporated political ideologies along with cultural beliefs this is seen with the Late Sicán in the north and the Casma in the South. Despite this, many areas kept distinctive aspects of their culture and some gained autonomy after the conquest. It has been argued that Chimú leaders conquered territories further away because of the deviations in inheritance. The opposition to this is that an El Niño that had caused the state to increase the extractive economy in place and get supplies from other areas of the Andes. This El Niño is theorized to have occurred around A.D. 1100 and would have caused the destruction of irrigation canals. Both arguments suggest that agriculture expansion led to increased identities socially and politically. The Chimú conquered the Jequetepeque around 1320 and changed the political structure of the society. Places like Pacatnamú were left behind and other sites like Farfán had increased laborers for administrative compounds constructed under the supervision of Imperial administrators. Land use, agricultural methods and settlement patterns of the Jequetepeque societies all changed after the conquest. Many households had to see tribute requirements and agricultural production increased. Downfall The state governed such social classes until the empire of the Sican culture conquered the kingdom of
