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.
History of clothing and textiles
We do not know what the people who constituted the Indus Valley Civilization, one of the earliest civilizations of the world, actually wore. Any cloth that might have been worn has long since disintegrated and we have not yet been able to decipher the Indus script. However, historians and archaeologists have managed to piece together some bits of information from clues found in sculptures and figurines.
