context_page_description: Mesoamerican chronology divides the history of prehispanic Mesoamerica into several periods: the Paleo-Indian, the Archaic, the Preclassic or Formative, the Classic, and the Postclassic, Colonial, and Postcolonial.
  The periodization of Mesoamerica by researchers is based on archaeological, ethnohistorical, and modern cultural anthropology research dating to the early twentieth century. Archeologists, ethnohistorians, historians, and cultural anthropologists continue to work to develop cultural histories of the region.
context_section_description: For many years, the Olmec culture was thought to be the 'mother culture' of Mesoamerica, because of the great influence that it exercised throughout the region. However, more recent perspectives consider this culture to be more of a process to which all the contemporary peoples contributed, and which eventually crystallized on the coasts of Veracruz and Tabasco. The ethnic identity of the Olmecs is still widely debated. Based on linguistic evidence, archaeologists and anthropologists generally believe that they were either speakers of an Oto-Manguean language, or (more likely) the ancestors of the present-day Zoque people who live in the north of Chiapas and Oaxaca. According to this second hypothesis, Zoque tribes emigrated toward the south after the fall of the major population centers of the Gulf plains. Whatever their origin, these bearers of Olmec culture arrived at the leeward shore some eight thousand years BCE, entering like a wedge among the fringe of proto-Maya peoples who lived along the coast, a migration that would explain the separation of the Huastecs of the north of Veracruz from the rest of the Maya peoples based in the Yucatán Peninsula and Guatemala.
  The Olmec culture represents a milestone of Mesoamerican history, as various characteristics that define the region first appeared there. Among them are the state organization, the development of the 260-day ritual calendar and the 365-day secular calendar, the first writing system, and urban planning. The development of this culture started 1600 to 1500 BCE, though it continued to consolidate itself up to the 12th century BCE. Its principal sites were La Venta, San Lorenzo, and Tres Zapotes in the core region. However, throughout Mesoamerica numerous sites show evidence of Olmec occupation, especially in the Balsas river basin, where Teopantecuanitlan is located. This site is quite enigmatic, since it dates from several centuries earlier than the main populations of the Gulf, a fact which has continued to cause controversy and given rise to the hypothesis that the Olmec culture originated in that region.
  Among the best-known expressions of Olmec culture are giant stone heads, sculptured monoliths up to three metres in height and several tons in weight. These feats of Olmec stonecutting are especially impressive when one considers that Mesoamericans lacked iron tools and that the heads are at sites dozens of kilometers from the quarries where their basalt was mined. The function of these monuments is unknown. Some authors propose that they were commemorative monuments for notable players of the ballgame, and others that they were images of the Olmec governing elite.
  The Olmec are also known for their small carvings made of jade and other greenstones. So many of the Olmec figurines and sculptures contain representations of the were-jaguar, that, according to José María Covarrubias, they could be forerunners of the worship of the rain god, or maybe a predecessor of the future Tezcatlipoca in his manifestation as Tepeyolohtli, the "Heart of the Mountain"
  The exact causes of the Olmec decline are unknown.
  In the Pacific lowlands of the Maya Area, Takalik Abaj c. 800 BCE, Izapa c. 700 BCE, and Chocola c. 600 BCE, along with Kaminaljuyú c. 800 BCE, in the central Highlands of Guatemala, advanced in the direction of what would be the Classic Maya culture. Apart from the West, where the tradition of the Tumbas de tiro had taken root, in all the regions of Mesoamerica the cities grew in wealth, with monumental constructions carried out according to urban plans that were surprisingly complex. La Danta in El Mirador, the San Bartolo murals, and the circular pyramid of Cuicuilco date from this time, as do the central plaza of Monte Albán and the Pyramid of the Moon in Teotihuacan.
  Toward the end of the Preclassic period, political and commercial hegemony shifted to the population centers in the Valley of Mexico. Around Lake Texcoco there existed a number of villages that grew into true cities: Tlatilco and Cuicuilco are examples. The former was found on the northern b
