Peruvian territory was home to ancient cultures spanning from the Norte Chico civilization in Caral, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty with its capital in Lima, which included most of its South American colonies.The earliest evidences of human presence in Peruvian territory have been dated to approximately 9,000 BC. Andean societies were based on agriculture, using techniques such as irrigation and terracing; camelid husbandry and fishing were also important. Organization relied on reciprocity and redistribution because these societies had no notion of market or moneyPeru covers 1,285,216 km2 (496,225 sq mi) of western South America. It borders Ecuador and Colombia to the north, Brazil to the east, Bolivia to the southeast, Chile to the south, and the Pacific Ocean to the west. The Andes Mountains run parallel to the Pacific Ocean; they define the three regions traditionally used to describe the country geographically. The costa (coast), to the west, is a narrow plain, largely arid except for valleys created by seasonal rivers.Peruvian culture is primarily rooted in Amerindian and Spanish traditions, though it has also been influenced by various Asian, African, and other European ethnic groups. Peruvian artistic traditions date back to the elaborate pottery, textiles, jewelry, and sculpture of Pre-Inca cultures. The Incas maintained these crafts and made architectural achievements including the construction of Machu Picchu. Baroque dominated colonial art, though modified by native traditions.
