=== Ancient Peru ===
The earliest evidence of agriculture in the Andean region dates to around 9000 BC in Ecuador at sites of the Las Vegas culture. The bottle gourd may have been the first plant cultivated. The oldest evidence of canal irrigation in South America dates to 4700 to 2500 BC in the Zaña Valley of northern Peru. The earliest urban settlements of the Andes, as well as North and South America, are dated to 3500 BC at Huaricanga, in the Fortaleza area, and Sechin Bajo near the Sechin River. Both sites are in Peru. The Caral–Supe or Norte Chico civilization is understood to have emerged around 3200 BC, as it is at that point that large-scale human settlement and communal construction across multiple sites becomes clearly apparent. In the early 21st century, Peruvian archaeologist Ruth Shady established Caral–Supe as the oldest known civilization in the Americas. The civilization flourished near the Pacific coast in the valleys of three small rivers, the Fortaleza, the Pativilca, and the Supe. These river valleys each have large clusters of sites. Further south, there are several associated sites along the Huaura River. Notable settlements include the cities of Caral, the largest and most complex Preceramic site, and Aspero. Norte Chico is distinguished by its density of large sites with immense architecture. Haas argues that the density of sites in such a small area is globally unique for a nascent civilization. During the third millennium BC, Norte Chico may have been the most densely populated area of the world (excepting, possibly, northern China). The Supe, Pativilca, Fortaleza, and Huaura River valleys each have several related sites. Norte Chico is unusual in that it completely lacked ceramics and apparently had almost no visual art. Nevertheless, the civilization exhibited impressive architectural feats, including large earthwork platform mounds and sunken circular plazas, and an advanced textile industry. The platform mounds, as well as large stone warehouses, provide evidence for a stratified society and a centralized authority necessary to distribute resources such as cotton. However, there is no evidence of warfare or defensive structures during this period. Originally, it was theorized that, unlike other early civilizations, Norte Chico developed by relying on maritime food sources in place of a staple cereal. This hypothesis, the Maritime Foundation of Andean Civilization, is still hotly debated; however, most researches now agree that agriculture played a central role in the civilization's development while still acknowledging a strong supplemental reliance on maritime proteins. The Norte Chico chiefdoms were "...almost certainly theocratic, though not brutally so," according to Mann. Construction areas show possible evidence of feasting, which would have included music and likely alcohol, suggesting an elite able to both mobilize and reward the population. The degree of centralized authority is difficult to ascertain, but architectural construction patterns are indicative of an elite that, at least in certain places at certain times, wielded considerable power: while some of the monumental architecture was constructed incrementally, other buildings, such as the two main platform mounds at Caral, appear to have been constructed in one or two intense construction phases. As further evidence of centralized control, Haas points to remains of large stone warehouses found at Upaca, on the Pativilca, as emblematic of authorities able to control vital resources such as cotton. Economic authority would have rested on the control of cotton and edible plants and associated trade relationships, with power centered on the inland sites. Haas tentatively suggests that the scope of this economic power base may have extended widely: there are only two confirmed shore sites in the Norte Chico (Aspero and Bandurria) and possibly two more, but cotton fishing nets and domesticated plants have been found up and down the Peruvian coast. It is possible that the major inland centers of Norte Chico were at the center of a broad regional trade network centered on these resources. Discover magazine, citing Shady, suggests a rich and varied trade life: "[Caral] exported its own products and those of Aspero to distant communities in exchange for exotic imports: Spondylus shells from the coast of Ecuador, rich dyes from the Andean highlands, hallucinogenic snuff from the Amazon." (Given the still limited extent of Norte Chico research, such claims should be treated circumspectly.) Other reports on Shady's work indicate Caral traded with communities in the Andes and in the jungles of the Amazon basin on the opposite side of the Andes. Leaders' ideological power was based on apparent access to deities and the supernatural. Evidence regarding Norte Chico religion is limited: an image of the Staff God, a leering figure with a hood and fangs, has been found on a gourd dated to 2250 BC. The Staff God is a major deity of later Andean cultures, and Winifred Creamer suggests the find points to worship of common symbols of gods. As with much other research at Norte Chico, the nature and significance of the find has been disputed by other researchers. The act of architectural construction and maintenance may also have been a spiritual or religious experience: a process of communal exaltation and ceremony. Shady has called Caral "the sacred city" (la ciudad sagrada): socio-economic and political focus was on the temples, which were periodically remodeled, with major burnt offerings associated with the remodeling. Bundles of strings uncovered at Norte Chico sites have been identified as quipu, a type of pre-writing recording device. Quipu are thought to encode numeric information, but some have conjectured that quipu have been used to encode other forms of data, possibly including literary or musical applications. However, the exact use of quipu by the Norte Chico and later Andean cultures has been widely debated. The presence of quipu and the commonality of religious symbols suggests a cultural link between Norte Chico and later Andean cultures. Circa 1800 BC, the Norte Chico civilization began to decline, with more powerful centers appearing to the south and north along the coast and to the east inside the belt of the Andes. Pottery eventually developed in the Amazon Basin and spread to the Andean culture region around 2000 BC. The next major civilization to arise in the Andes would be the Chavín culture at Chavín de Huantar, located in the Andean highlands of the present-day Department of Ancash. It is believed to have been built around 900 BC and was the religious and political center of the Chavín people.
