Influence

By around 2200 BC, the influence of Norte Chico civilization spread far along the coast. To the south, it went as far as the Chillon valley, and the site of El Paraiso. To the north, it spread as far as the Santa River valley.

c. 1800 BC, the Caral–Supe 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. The success of irrigation-based agriculture at Caral–Supe may have contributed to its being eclipsed. Anthropologist Professor Winifred Creamer of Northern Illinois University notes that "when this civilization is in decline, we begin to find extensive canals farther north. People were moving to more fertile ground and taking their knowledge of irrigation with them". It would be a thousand years before the rise of the next great Peruvian culture, the Chavín.
