===Olmecs (1500–400 BCE)===
{{main|Olmec}}
The Olmec first appeared along the Atlantic coast (in what is now the state of [[Tabasco]]) in the period 1500–900 BCE. The Olmecs were the first Mesoamerican culture to produce an identifiable artistic and cultural style and may also have been the society that invented writing in Mesoamerica. By the Middle Preclassic Period (900–300 BCE), Olmec artistic styles had been adopted as far away as the Valley of Mexico and Costa Rica.
