Olmecs

Earliest known major Mesoamerican civilization

The Olmecs or Olmec were an early major Mesoamerican civilization, flourishing in the modern-day Mexican states of Veracruz and Tabasco from roughly 1200 to 400 BC during Mesoamerica's formative period. They are known as one of the cradles of civilization. The Olmecs were initially centered at the site of their development in San Lorenzo Tenochtitlán, but moved to La Venta in the 10th century BC following the decline of San Lorenzo.
