1. Events
January 1499 BC: Olmec expansion by 1500 BC. The Olmecs were the earliest known major Mesoamerican civilization.
January 399 BC: The population in the eastern half of the Olmec heartland dropped precipitously, and the area was sparsely inhabited until the 19th century. According to archaeologists, this depopulation was probably the result of "very serious environmental changes that rendered the region unsuited for large groups of farmers", in particular changes to the riverine environment that the Olmec depended upon for agriculture, hunting and gathering, and transportation. These changes may have been triggered by tectonic upheavals or subsidence, or the silting up of rivers due to agricultural practices.
Disestablishment
January 349 BC: The Epi-Olmec culture was a cultural area in the central region of the present-day Mexican state of Veracruz. Concentrated in the Papaloapan River basin, a culture that existed during the Late Formative period, from roughly 300 BC to roughly 250 AD. Epi-Olmec was a successor culture to the Olmec, hence the prefix "epi-" or "post-". Although Epi-Olmec did not attain the far-reaching achievements of that earlier culture, it did realize, with its sophisticated calendrics and writing system, a level of cultural complexity unknown to the Olmecs.
