began to domesticate the llama and reduced deer hunting. Evidence of increased exchange with outside civilizations is also seen at this time. The Jarabarriu, the final stage of the Chavín Horizon, lasted from about 400 to 250 BCE. Chavín culture had a dramatic increase in population. The settlement pattern changed to a proto-urban pattern, consisting of a center of lowland valley peoples and smaller satellite communities in the surrounding higher altitude areas. The culture showed specialization and social differentiation. The people who lived in the east at Chavín de Huántar are thought to have had lower prestige than the communities around the ceremonial center. A diverse and intense production of ceramics is suggested during the Jarabarriu phase, when the valley was heavily populated and the ceramic style more defined. Satellite communities also developed centers of production during this phase. Presence of elite At Chavín, power was legitimized through the belief in the small elite having a divine connection; shamans derived power and authority from their claim to a divine connection. The community believed in and had a desire to connect with the divine. With asymmetrical power, there is often evidence of the manipulation of traditions. Strategic manipulation is a vehicle of change which shamans could use to produce authority. During the Chavín horizon, large changes were taking place. "The greater degree of elaboration of persuasion evident in the rites, materials, and settings of the belief system, the more likely that not only were the leaders aware of being self-serving in their actions but also they were actually conscious of the trajectory change." The archeological evidence shows several examples of reinterpretation, use of psychotropic drugs, and landscape altering. It also shows the complex planning and construction of stone-walled galleries. The concept of invented tradition refers to a situation in which outside elements are newly brought together to depict a seemingly old tradition. This can be seen generally in the architecture at Chavín de Huántar, which bring together many aspects of outside cultures to create a unique new, yet traditional appearance. The use of psychotropic drugs introduces a medium for manipulation. Only indirect evidence supports the use of psychotropic drugs, as noted above. Scholars have not been able to determine if the San Pedro cactus was ingested, who consumed the cactus: only the shaman elite, or more widespread among the masses. If the masses were taking the cactus, they would be more
