The term Meso-America denotes the part of Mexico and Central America that was civilized in pre-Spanish times. In many respects, the American Indians who inhabited Meso-America were the most advanced native peoples in the Western Hemisphere. The northern border of Meso-America runs west from a point on the Gulf coast of Mexico above the modern port of Tampico, then dips south to exclude much of the central desert of highland Mexico, meeting the Pacific coast opposite the tip of Baja (Lower) California. On the southeast, the boundary extends from northwestern Honduras on the Caribbean across to the Pacific shore in El Salvador. Thus, about half of Mexico, all of Guatemala and Belize, and parts of Honduras and El Salvador are included in Meso-America.

Geographically and culturally, Meso-America consists of two strongly contrasted regions: highland and lowland. The Mexican highlands are formed mainly by the two Sierra Madre ranges that sweep down on the east and west. Lying athwart them is a volcanic cordillera stretching from the Atlantic to the Pacific. The high valleys and landlocked basins of Mexico were important centres of pre-Spanish civilization. In the southeastern part of Meso-America lie the partly volcanic Chiapas-Guatemala highlands. The lowlands are primarily coastal. Particularly important was the littoral plain extending south along the Gulf of Mexico, expanding to include the Petén-Yucatán Peninsula, homeland of the Mayan peoples.

Agriculture in Meso-America was advanced and complex. A great many crops were planted, of which corn, beans, and squashes were the most important. In the highlands, hoe cultivation of more or less permanent fields was the rule, with such intensive forms of agriculture as irrigation and chinampas (the so-called floating gardens reclaimed from lakes or ponds) known in some regions. In contrast, lowland agriculture was frequently of the slash-and-burn variety; a patch of jungle was first selected, felled and burned toward the end of the dry season, and then planted with a digging stick in time for the first rains. After a few years of planting, the field was abandoned to the forest, as competition from weeds and declining soil fertility resulted in diminishing yields. There is good evidence, however, that the slash-and-burn system of cultivation was often supplemented by "raised-field" cultivation in the lowlands; these artificially constructed earthen hillocks built in shallow lakes or marshy areas were not unlike the chinampas of the Mexican highlands. In addition, terraces were constructed and employed for farming in some lowland regions. Nevertheless, the demographic potential for agriculture was probably always greater in the highlands than it was in the lowlands, and this was demonstrated in the more extensive urban developments in the former area.

The extreme diversity of the Meso-American environment produced what has been called symbiosis among its subregions. Interregional exchange of agricultural products, luxury items, and other commodities led to the development of large and well-regulated markets in which cacao beans were used for money. It may have also led to large-scale political unity and even to states and empires. High agricultural productivity resulted in a nonfarming class of artisans who were responsible for an advanced stone architecture, featuring the construction of stepped pyramids, and for highly evolved styles of sculpture, pottery, and painting.

The Meso-American system of thought, recorded in folding-screen books of deerskin or bark paper, was perhaps of even greater importance in setting them off from other New World peoples. This system was ultimately based upon a calendar in which a ritual cycle of 260 (13 20) days intermeshed with a "vague year" of 365 days (18 20 days, plus five "nameless" days), producing a 52-year Calendar Round. The religious life was geared to this cycle, which is unique to them. The Meso-American pantheon was associated with the calendar and featured an old, dual creator god; a god of royal descent and warfare; a sun god and moon goddess; a rain god; a culture hero called the Feathered Serpent; and many other deities. Also characteristic was a layered system of 13 heavens and nine underworlds, each with its presiding god. Much of the system was under the control of a priesthood that also maintained an advanced knowledge of astronomy.

As many as 14 language families were found in Meso-America, but most can be grouped into three large "phyla": Uto-Aztecan, Macro-Mayan, and Oto-Manguean. A dominant role was played by Uto-Aztecan, particularly by speakers of the Nahua groups of which Náhuatl, official tongue of the Aztec Empire, was the most important. While Macro-Mayan includes Zoquean and Totonacan, its largest member is Mayan, with a number of mutually unintelligible languages, at least some of which were spoken by the inhabitants of the great Maya ceremonial centres. The modern Mexican state of Oaxaca is now the centre of the heterogeneous Oto-Manguean phylum; but the only linguistic groups that played any great part in Meso-American civilization were the Mixtec and Zapotec, both of which had large, powerful kingdoms at the time of the Spanish conquest. Still a linguistic puzzle are such languages as Tarascan, mother tongue of an "empire" in western Mexico that successfully resisted Aztec encroachments; it has no sure relatives, although some linguistic authorities have linked it with the Quechua language of distant Peru. Huavean and Xinca-Lencan are little-known language groups of southeastern Meso-America.

Mesoamerican Timeline

The Archaic Period 7000 - 2000 BC

Hunter-gatherer culture prevalent until late in this period when slightly more permanent settlement patterns evolve. (ca. 2000 - 1500 BC)

 The Olmecs 1500 - 200 BC

(Preclassic/Formative Period)

1500 BC - "Mother Culture of Ancient Mexico" and surrounding areas: The Olmecs. The Olmecs layed foundations for the Zapotecs, Maya, and Aztecs.

The first agricultural settlements show up, as well as the ceremonial center at San Lorenzo ca. 1200 BC. San Lorenzo is destroyed ca. 900 BC and La Venta is established. Smaller objects excavated in Mexico, Belize, Guatemala, and Honduras from this time period reveal how widespread Olmec cultural, commercial, and artistic influence was.

400 BC - The beginning of the decline of the Olmecs. The Olmecs start to disappear around 400 BC. They are replaced by the Zapotecs of Oaxaca and the nascent Maya.

The Zapotecs 600 BC - AD 800

Settle in Oaxaca - are known for their advances in mathematics and a calendar.

Teotihuacan Culture AD 200 - 900

Located in central Mexico, they are the center of the cults of the Great Goddess and the Feathered Serpent. After the destruction of Cuicuilco in AD 100, their culture develops from 250 - 700. The final abandonment of Teotihuancan cities occurs around AD 900.

El Tajin Civilization AD 250 - 900

Classic Maya AD 250 - 950

The Maya initially drew on the cultural inheritance of the Olmecs and Teotihuacan. Their zenith is from ca. 300 - 800. Toltec takeover of Maya cities on the Yucatan occurs around AD 900.

Post Classic Period AD 950 - 1500

Toltecs occupy area in the Yucatan previously occupied by the Maya. Internecine warfare continues to weaken Toltec/Maya peoples, and the Maya are conquered by the Spanish in 1524.

Aztecs AD 1200 - 1521

AD 1300 - 1500 - The height of the Aztec empire. Technotitlan is populated by over 200,000 people.

Miztecs AD 800 - 1500

AD 800 - Monte Alban declines, there is archaeological evidence that a different population was present, but there was not much conflict. These people, called the Miztecs, which means "People of the Clouds" had their home in northern and western Oaxaca. Their existence was based on the coexistence of small kingdoms. 8 Deer attempted to unify the kingdoms in the 11th century, but the larger unified state disintegrated after his death.

After 900, the Miztecs dominate Oaxaca. In earlier times, the. In earlier times, the were strongly influenced by contact with the Toltecs, but around AD 1200, the develop independently (Monte Alban and the large number of tombs there are evidence for this).
