The Olmec: The Olmec were the first great Mesoamerican civilization. They thrived along Mexicoâs gulf coast, mainly in the present-day states of Veracruz and Tabasco, from about 1200 to 400 B.C., although there were pre-Olmec societies before that and post-Olmec (or Epi-Olmec) societies afterwards.wo major Olmec cities are known to researchers: San Lorenzo and La Venta.
