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.
Zapotec civilization
The Zapotec civilization ( "The People" 700 BC–1521 AD) was an indigenous pre-Columbian civilization that flourished in the Valley of Oaxaca in Mesoamerica. Archaeological evidence shows that their culture goes back at least 2,500 years. The Zapotec left archaeological evidence at the ancient city of Monte Albán in the form of buildings, ball courts, magnificent tombs and grave goods including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica and the center of a Zapotec state that dominated much of the territory that today belongs to the Mexican state of Oaxaca.
