Pre-Columbian era
The earliest known civilization is the Olmec. This civilization established the cultural blueprint by which all succeeding indigenous civilizations would follow in Mexico. Pre-Olmec civilization began with the production of pottery in abundance, around 2300 BCE in the Grijalva River delta. Between 1600 and 1500 BCE, the Olmec civilization had begun, with the consolidation of power at their capital, a site today known as San Lorenzo Tenochtitlán near the coast in southeast Veracruz. The Olmec influence extended across Mexico, into Central America, and along the Gulf of Mexico. They transformed many peoples' thinking toward a new way of government, pyramid-temples, writing, astronomy, art, mathematics, economics, and religion. Their achievements paved the way for the Maya civilization and the civilizations in central Mexico.
Chimú culture
The oldest civilization present on the north coast of Peru is the Moche or Mochica civilization, which is identified as Early Chimú. The start of this period is not known for certain, but it ended around 700 AD. It was centered in the Chicama, Moche, and Viru Valleys. "Many large pyramids are attributed to the Early Chimú period." (37) These pyramids are built of adobe in rectangular shapes made from molds. "Early Chimú cemeteries are also found without pyramid associations. Burials are usually in extended positions, in prepared tombs. The rectangular, adobe-lined and covered tombs have niches in their walls in which bowls were placed." (39)
