Mesoamerican chronology divides the history of prehispanic Mesoamerica into several periods: the Paleo-Indian (first human habitation until 3500 BCE); the Archaic (before 2600 BCE), the Preclassic or Formative (2500 BCE – 250 CE), the Classic (250–900 CE), and the Postclassic (); as well as the post European contact Colonial Period (1521–1821), and Postcolonial, or the period after independence from Spain (1821–present).
The periodisation of Mesoamerica by researchers is based on archaeological, ethnohistorical, and modern cultural anthropology research dating to the early twentieth century. Archaeologists, ethnohistorians, historians, and cultural anthropologists continue to work to develop cultural histories of the region.
Overview
Paleo-Indian period
10,000–3500 BCE
The Paleo-Indian (less frequently, Lithic) period or era is that which spans from the first signs of human presence in the region, which many believe to have happened due to the Bering Land Bridge, to the establishment of agriculture and other practices (e.g. pottery, permanent settlements) and subsistence techniques characteristic of proto-civilisations. In Mesoamerica, the termination of this phase and its transition into the succeeding Archaic period may generally be reckoned at between 10,000 and 8000 BCE. This dating is approximate only and different timescales may be used between fields and sub-regions.
Archaic Era
Before 2600 BCE
During the Archaic Era agriculture was developed in the region and permanent villages were established. Late in this era, use of pottery and loom weaving became common, and class divisions began to appear. Many of the basic technologies of Mesoamerica in terms of stone-grinding, drilling, pottery etc. were established during this period.
Preclassic Era or Formative Period
2000 BCE – 250 CE
During the Preclassic Era, or Formative Period, large-scale ceremonial architecture, writing, cities, and states developed. Many of the distinctive elements of Mesoamerican civilisation can be traced to this period, including the dominance of corn, the building of pyramids, human sacrifice, jaguar-worship, the complex calendar, and many of the gods.
The Olmec civilization developed and flourished at such sites as La Venta and San Lorenzo Tenochtitlán, eventually succeeded by the Epi-Olmec culture between 300–250 BCE. The Zapotec civilization arose in the Valley of Oaxaca, the Teotihuacan civilisation arose in the Valley of Mexico. The Maya civilization began to develop in the Mirador Basin (in modern-day Guatemala) and the Epi-Olmec culture in the Isthmus of Tehuantepec (in modern-day Chiapas), later expanding into Guatemala and the Yucatan Peninsula.
In Central America, there were some Olmec influences, the archaeological sites of Los Naranjos and Yarumela in Honduras stand out, built by ancestors of the Lencas, which reflect an architectural influence of this culture on Central American soil. Other sites with possible Olmec influence have been reported, such as Puerto Escondido, in the Sula Valley, near La Lima, and Hato Viejo in the department of Olancho, where a jadeite statuette has been found that shares many characteristics with those found in Mexico.
Classic Period
250–900 CE
The Classic Period was dominated by numerous independent city-states in the Maya region and also featured the beginnings of political unity in central Mexico and the Yucatán. Regional differences between cultures grew more manifest. The city-state of Teotihuacan dominated the Valley of Mexico until the early 8th century, but little is known of the political structure of the region because the Teotihuacanos left no written records. The city-state of Monte Albán dominated the Valley of Oaxaca until the late Classic, leaving limited records in their script, which is as yet mostly undeciphered. Highly sophisticated arts such as stuccowork, architecture, sculptural reliefs, mural painting, pottery, and lapidary developed and spread during the Classic era.
In the Maya region, under considerable military influence by Teotihuacan after the "arrival" of Siyaj K'ak' in 378 CE, numerous city states such as Tikal, Uaxactun, Calakmul, Copán, Quirigua, Palenque, Cobá, and Caracol reached their zeniths. Each of these polities was generally independent, although they often formed alliances and sometimes became vassal states of each other. The main conflict during this period was between Tikal and Calakmul, which fought a series of wars over the course of more than half a millennium. Each of these states declined during the Terminal Classic and were eventually abandoned.
