Olmec Civilization
650 BCE – 351 BCE · 17,603 km²
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.

Origins and Founding
Pre-Olmec cultures had flourished since about 2500 BC, and it has been speculated that the Olmecs derived in part from the neighboring Mokaya or Mixe–Zoque cultures which developed during this time. The beginnings of Olmec civilization have traditionally been placed between 1400 BC and 1200 BC. Past finds of Olmec remains ritually deposited at the shrine El Manatí near the triple archaeological sites known collectively as San Lorenzo Tenochtitlán moved this back to at least 1600–1500 BC. It seems that the Olmec had their roots in early farming cultures of Tabasco, which began between 5100 BC and 4600 BC. These shared the same basic food crops and technologies of the later Olmec civilization.

What is today called Olmec first appeared fully within San Lorenzo Tenochtitlán, where distinctive Olmec features occurred around 1400 BC.

Government, Society and Religion
Little is directly known about the societal or political structure of Olmec society. Although it is assumed by most researchers that the colossal heads and several other sculptures represent rulers, nothing has been found like the Maya stelae which name specific rulers and provide the dates of their rule.

Instead, archaeologists relied on the data that they had, such as large- and small-scale site surveys. These provided evidence of considerable centralization within the Olmec region, first at San Lorenzo and then at La Venta – no other Olmec sites come close to these in terms of area or in the quantity and quality of architecture and sculpture.

Economy and Trade
The wide diffusion of Olmec artifacts and "Olmecoid" iconography throughout much of Mesoamerica indicates the existence of extensive long-distance trade networks. Exotic, prestigious and high-value materials such as greenstone and marine shell were moved in significant quantities across large distances. Some of the reasons for trade revolve around the lack of obsidian in the heartland. The Olmec used obsidian in many tools because worked edges were very sharp and durable. Specifically, prismatic blades, a type of obsidian tool was the primary cutting tool used within households. Obsidian was highly valued in Mesoamerica. Most of the obsidian found has been traced back to Guatemala showing the extensive trade.

Achievements and Monuments
Although the archaeological record does not include explicit representation of Olmec bloodletting, researchers have found other evidence that the Olmec ritually practiced it. For example, numerous natural and ceramic stingray spikes and maguey thorns have been found at Olmec sites, and certain artifacts have been identified as bloodletters.

The argument that the Olmec instituted human sacrifice is significantly more speculative. No Olmec or Olmec-influenced sacrificial artifacts have yet been discovered; no Olmec or Olmec-influenced artwork unambiguously shows sacrificial victims (as do the danzante figures of Monte Albán) or scenes of human sacrifice (such as can be seen in the famous ballcourt mural from El Tajín).

Decline and Fall
Scholars have yet to determine the cause of the eventual extinction of the Olmec culture. Between 400 and 350 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 siltation of rivers due to agricultural practices.

One theory for the considerable population drop during the Terminal Formative period is suggested by Santley and colleagues (Santley et al.
