Pre-Columbian Americas: Key Civilizations and Societal Structures

Origins and Migration to the Americas

• Most Native American origin stories assert that native nations have always called the Americas home.
• Some scholars propose a land bridge between Asia and North America, called Beringia, existing around $9{,}000{-}15{,}000\ \text{years ago}$.
• After the glaciers melted, water flooded Beringia and the Bering Strait formed.
• Later populations likely crossed the strait by boat as well.
• The presence of shared genetic markers on the y chromosome between Asians and Native Americans lends credibility to this migration theory.
• Populations continually moved southward, eventually populating both North and South America and giving rise to diverse cultures—from urban, centralized civilizations to numerous Woodland groups in Eastern North America.
• Recent coastal archaeology along the West Coast of South America suggests some migrants traveled by water along the coast in addition to overland routes.
• Around $10{,}000\ \text{years ago}$, humans began domesticating plants and animals, adding agriculture to hunting and gathering.
• This agricultural revolution supported larger, more reliable food supplies and enabled more settled, permanent settlements.
• In the Americas, agriculture and settled life became especially evident in Mesoamerica (refer to Fig. 1.3 for a map of major Western Hemisphere civilizations).
• In South America, early civilizations tended to develop along the coast, because the High Andes and the Amazon Basin interior were less favorable for settlement.

The Olmec and the Rise of Mesoamerican Civilizations

• The Olmec are considered the mother culture of Mesoamerica, flourishing along the Gulf Coast of Mexico from about $c. ext{1200 BCE}$ to $c. ext{400 BCE}$.
• They were polytheistic; their gods combined male and female traits and demanded blood sacrifices from enemies captured in war or ritual bloodletting.
• Maize (corn) was domesticated by ext{c}.}\ 5000\ \text{BCE} and formed the basis of the Olmec diet.
• They developed a mathematic system, built monumental structures, and devised a calendar that could predict eclipses and solstices; priest-astronomers used this calendar to direct planting and harvests.
• The Olmec created the only known written language in the Western Hemisphere and established long-distance trade networks that diffused culture.
• They produced obisidian weapons, jade jewelry, featherwork, and cacao beans used in a chocolate drink, all central to commerce.
• The Olmec built major works along the Gulf Coast, including巨头 head sculptures and the Pyramid at La Venta; they constructed aqueducts to bring water into cities and irrigate fields.
• Food staples included maize, squash, beans, and tomatoes; they bred small domesticated dogs and relied on fish for protein.
• They worshiped the rain god, maize god, and the feathered serpent (Quetzalcoatl in Aztec, Cucullcan in Maya).
• The Olmec also developed a regional trade network and fostered an emerging elite class.

Teotihuacan, then the Maya: Early Urbanism and Maya Civilizations

• After Olmec decline, Teotihuacan rose in the central Gulf Coast region near modern Mexico City, quickly becoming one of the largest urban centers in the pre-Columbian Americas (population over $ext{100{,}000}$ at its height).
• The ethnicity of Teotihuacan’s inhabitants is debated; it may have been multiethnic.
• The city’s economy supported large-scale agriculture, enabling specialization in crafts and trades.
• Teotihuacan featured more than $ext{2{,}200}$ apartment compounds for multiple families and over $ext{100}$ temples, including the Pyramid of the Sun (≈ $200\ \text{ft}$ tall) and the Pyramid of the Moon (≈ $150\ \text{ft}$ tall).
• Graves near the Temple of the Feathered Serpent suggest ritual human sacrifice.
• The city was a major center of long-distance trade across Mesoamerica.
• The Maya were a distinct and influential civilization in the region of present-day Mexico, Belize, Honduras, and Guatemala; they maintained strong ties to Teotihuacan.
• The Maya contributed significantly in architecture, mathematics, and astronomy; developed a calendar and a writing system to record crop yields, population, and trade data; built city-states such as Copan, Tikal, and Chichén Itzá (Chikanitsa in the text).
• The Maya built temples, statues, pyramids, and astronomical observatories along major trade routes.
• The Maya’s civilization declined around $900\ CE$ due to poor soils and a nearly two-century drought.
• The Castillo temple at Chichén Itzá (often cited as a major Maya site) features a 365-step stairway (the number of days in a year) on its sides; this detail illustrates Maya calendrical knowledge.
• The Spaniards found little organized resistance among the Maya after their arrival in the 1520s; Maya glyphs and codices survived until the sixteenth century.
• Some Mayan codices were burned in $1562\ CE$ by bishop Diego de Landa, who feared conversion failures; only a few codices survive today.
• Modern access to codices and facsimiles is available through university libraries and digital resources (e.g., Mayan codices descriptions and facsimiles).

The Aztec Empire

• When Hernán Cortés arrived on the Mexican coast in the early 16th century, he encountered Tenochtitlan, a vast Aztec (Mexica) city on an island in Lake Texcoco with a powerful ruler, Moctezuma.
• Aztec legend held that their people left the homeland of Aztlan and founded their capital on Lake Texcoco; in 1325, they began construction of Tenochtitlan on an island in the lake.
• By 1519, Tenochtitlan housed around $200{,}000$ inhabitants and was the largest city in the Western Hemisphere, renowned for its wealth and complex courts.
• The Spaniards were struck by the city’s order, cleanliness, and structure; Bernal Díaz del Castillo described its towers and canals, noting how it differed from European cities of the time.
• The Aztec built an organized urban core with neighborhoods for specific occupations, a trash collection system, markets, two aqueducts for fresh water, and public buildings and temples.
• They farmed with reed barges filled with soil on lake waters, creating chinampas (floating gardens) such as Xaquemilco (Xochimilco) that are still visible today.
• The Aztec economy and religion reflected a warrior-noble and priestly elite who conducted daily human sacrifices to sustain the sun and ensure agricultural productivity; sacrifices included removing the still-beating heart with an obsidian knife from captives or criminals, with the body discarded from temple heights (as depicted in Figure 1.7).
• Each Aztec god governed an aspect of the natural world (heavens, farming, rain, fertility, sacrifice, combat), and ritual offerings were central to maintaining cosmic order and agricultural success.
• The Florentine Codex, compiled by Bernardino de Sahagún in the 16th century, records Aztec history and prophecy, including a pre-contact dream of Spanish arrival recounted by an elder from Xochimilco to Moctezuma.

The Inca Empire

• The Inca, whose name means “lord” or “ruler” in Quechua, formed the most highly developed and expansive South American state, stretching approximately $2{,}500\ \text{miles}$ along the Pacific coast and across the Andes to present-day Colombia in the north and Chile in the south.
• The Inca built roads across challenging Andean terrains, with an elevation of up to $14{,}000\ ext{ft}$ above sea level, designed for rapid movement of military and administrators.
• They did not use axle-mounted wheels; instead, they built stepped roads and a relay system of runners called chasques (chsqu) to transmit messages quickly across vast distances.
• The Inca lacked a traditional writing system; instead, they used quipu, a system of colored strings and knots to record information and maintain administrative records.
• They worshiped the sun and viewed gold as the sweat of the sun; the ruling class lived in wealth, while peasants paid labor obligations and taxes.
• The Inca practiced relatively little human sacrifice, preferring offerings of food, clothing, and coca leaves; in times of dire emergency, they sacrificed prisoners, and in some cases selected and well-fed children were offered as the ultimate sacrifice to ensure favorable afterlife outcomes.
• The Inca economy relied on redistribution: a third of crops went to the ruler, a third was stored for times of need, and peasants kept about one third for themselves; peasants also performed public works for the state.
• Machu Picchu, an extraordinary Inca site, was built around $1450\ CE$ and abandoned roughly a century later; Hiram Bingham rediscovered it in $1911\ CE$ and UNESCO designated it a World Heritage Site in $1983\ CE$.

North American Southwest: The Pueblo Peoples

• Native American societies in the southwestern United States included several groups collectively known as the Pueblo (named by the Spanish for their town-like settlements).
• The three main Pueblo groups were the Mogollon, Hohokam, and Anasazi.
• Mogollon (in the Gila Valley, New Mexico) flourished around the period until about $1450\ CE$, noted for painted bowls with geometric figures and wildlife motifs (e.g., birds) in black on white.
• Hohokam built an extensive irrigation system of canals; by $1300\ CE$ their communities supported large populations; they produced red-on-buff pottery and turquoise jewelry.
• Anasazi (meaning “ancient ones”) constructed cliff dwellings accessed by ladders or ropes; cliff pueblos (e.g., in Canyon de Chelly NM and Mesa Verde CO) used rope or ladder access and could be withdrawn for safety.
• By the 13th century, Anasazi and related Pueblo centers along roads (roughly $180\ ext{miles}$) connected smaller urban centers to Chaco Canyon, which had become the administrative, religious, and cultural heart of their civilization.
• By approximately the late 13th to early 14th century, drought and other pressures contributed to the abandonment of these settlements.
• Present-day descendants include the Hopi and Zuni.

The Hopewell, Cahokia, and the Eastern Woodlands

• The Hopewell culture occupied the Ohio River Valley from around the first century CE through about $400{-}500\ CE$, with settlements that were typically small hamlets.
• They practiced agriculture supplemented by hunting and fishing and developed extensive trade networks across regions from Canada to Louisiana.
• Materials such as shells, copper from Canada, and obsidian from the Rocky Mountains flowed through these trade networks, yielding necklaces, woven mats, and intricate carvings.
• The Hopewell left behind large burial mounds and earthworks, indicating social stratification within their communities.
• Cahokia, near present-day St. Louis, was perhaps the largest indigenous population center in North America, covering about $5\ ext{square miles}$ and housing more than $10{,}000$ residents, with tens of thousands more living on surrounding farms.
• Cahokia contained around $120$ earthen mounds or pyramids; each mound housed a leader who held authority over its neighborhood, with the largest mound covering $15\ ext{acres}$.
• Cahokia served as a hub of political and trade activity along the Mississippi River; it declined after around $1300\ CE$, possibly due to environmental limits that could not sustain a large population.
• East of the Mississippi, Native peoples were widespread in small, autonomous clans or tribal units rather than unified states; warfare among tribes was common as they competed for hunting and fishing territories.
• European explorers in the 16th and 17th centuries expected to find the same wealth as in the south, but instead encountered dispersed communities rich in land, timber, and fur; diseases carried by the Spanish devastated many communities.
• Across the Eastern Woodlands, leadership often involved a council of elders with women who selected and advised the male leader, indicating gender roles that were less fixed than in Europe or the Mesoamerican states.

Connections, Significance, and Implications

• The long durée of pre-Columbian societies demonstrates a continuum of innovation across agriculture, architecture, writing systems (Maya), calendrical science, and complex social structures across diverse environments.
• Trade networks linked distant regions, facilitating cultural diffusion and technological exchange (e.g., Olmec influence on later Maya and Aztec traditions).
• The rise and fall of large urban centers (Teotihuacan, Cahokia, Maya, and the Inca) illustrate how environmental factors (soil fertility, drought, resource management) and political organization shape urban longevity.
• The juxtaposition of extensive state-level civilizations (Maya, Aztec, Inca) with highly dispersed, smaller-scale societies (Eastern Woodlands, Pueblo) shows a wide spectrum of sociopolitical organization in the Americas prior to contact with Europeans.
• Ethical, philosophical, and practical implications discussed in class include the role of ritual practices (e.g., human sacrifice in Aztec religion), the use of symbolic commodities (gold, cacao, turquoise), and the transformations caused by European contact (disease, conquest, and cultural disruption).
• For further study, note the dates and key sites: $1325\ CE$ (founding of Tenochtitlan), $1519\ CE$ (Cortés arrival), $1562\ CE$ (burning of codices), $1911\ CE$ (Machu Picchu rediscovery), and UNESCO designation in $1983\ CE$ for Machu Picchu; key sites include Teotihuacan, Tenochtitlan, Chichén Itzá, Cahokia, and Machu Picchu.
