Olmecs

The Olmecs (/ˈɒlmɛks, ˈoʊl-/) 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 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. By about 400 BC the major centres of the Olmec civilization had been abandoned, and the population of the eastern half of the Olmec heartland dropped precipitously. The settlement density in that area remained much lower than during the height of Olmec dominance, and only intermittent occupation is evident until much later. Although the Olmec cultural style waned, elements of their tradition lived on in successor societies.

Among other "firsts", the Olmec appeared to practice ritual bloodletting and played the Mesoamerican ballgame, hallmarks of nearly all subsequent Mesoamerican societies. The aspect of the Olmecs most familiar now is their artwork, particularly the colossal heads. The Olmec civilization was first defined through artifacts which collectors purchased on the pre-Columbian art market in the late 19th and early 20th centuries. Olmec artworks are considered among ancient America's most striking.

The term Olmecs is derived from the Nahuatl Ōlmēcatl [oːlˈmeːkat͡ɬ] (singular) or Ōlmēcah [oːlˈmeːkaʔ] (plural). This word is composed of the two words ōlli [ˈoːlːi], meaning "natural rubber", and mēcatl [ˈmeːkat͡ɬ], meaning "people". Thus literally meaning "rubber people" in Nahuatl.

Rubber for the balls used in the ceremonial ballgame was produced by the people in the Gulf Lowlands dating back to as early as 1600 BC. The process involved extracting latex from a rubber tree common in the area, Castilla elastica, and mixing the latex with the juice of a local vine, Ipomoea alba. The Nahuas (including Aztec) called their contemporary neighbors in the Gulf Lowlands "rubber people" but this was documented some 2,000 years after the end of the ancient Olmec culture. Archaeologists in the early 20th century mistakenly applied the name "Olmec" to the rediscovered ruins and artifacts in the heartland decades before it was understood that they were not created by the same "rubber people" that were contemporary with the Aztecs. Despite the mistaken identity, the name has stuck.

It is not known what name the ancient Olmec used for themselves; some later Mesoamerican accounts seem to refer to the ancient Olmec as "Tamoanchan". A contemporary term sometimes used for the Olmec culture is tenocelome, meaning^{[clarification needed]} "mouth of the jaguar".

The Olmec heartland is the area in the Gulf lowlands where it expanded after early development in Soconusco, Veracruz. This area is characterized by swampy lowlands punctuated by low hills, ridges, and volcanoes. The Sierra de los Tuxtlas rises sharply in the north, along the Gulf of Mexico's Bay of Campeche. Here, the Olmec constructed permanent city-temple complexes at San Lorenzo Tenochtitlán, La Venta, Tres Zapotes, and Laguna de los Cerros. In this region, the first Mesoamerican civilization emerged and reigned from c. 1400–400 BC.

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. The rise of civilization was assisted by the local ecology of well-watered alluvial soil, as well as by the transportation network provided by the Coatzacoalcos river basin. This environment may be compared to that of other ancient centers of civilization such as the Nile, Indus, Yellow River and Mesopotamia. This highly productive environment encouraged a densely concentrated population, which in turn triggered the rise of an elite class. The elite class created the demand for the production of the symbolic and sophisticated luxury artifacts that define Olmec culture. Many of these luxury artifacts were made from materials such as jade, obsidian, and magnetite, which came from distant locations and suggest that early Olmec elites had access to an extensive trading network in Mesoamerica. The source of the most valued jade was the Motagua River valley in eastern Guatemala, and Olmec obsidian has been traced to sources in the Guatemala highlands, such as El Chayal and San Martín Jilotepeque, or in Puebla, distances ranging from 200 to 400 km (120 to 250 mi) away, respectively.
