Notes on Pre-Columbian Americas: Migrations, Civilizations, and Native North American Cultures

Origins of the First Americans

• Most Native American origin stories claim the Americas have always been home to Indigenous peoples; some scholars propose a migration window of about $9{,}000 ext{ to } 15{,}000 ext{ years ago}$ via a land bridge between Asia and North America known as Beringia.
  • The first inhabitants moved across this bridge seeking food; later, as glaciers melted, water flooded Beringia and formed the Bering Strait, and some populations crossed by boat across the strait.
  • Genetic evidence: shared Y-chromosome markers between Asians and Native Americans supports a common ancestry and migration theory.
• Migration patterns and settlement
  • After initial migration, populations moved continually southward, populating both North and South America and developing diverse cultures.
  • Examples of cultural diversity: highly urban Aztec civilization in what is now Mexico City; woodland tribes of eastern North America.
  • Recent coastal migration theories: research along the west coast of South America suggests some migrants traveled by water as well as land.
• Agricultural revolution and sedentism
  • Around $10{,}000 ext{ years ago}$, humans began domesticating plants and animals, adding agriculture to hunting and gathering.
  • The agricultural revolution allowed more reliable food supplies, population growth, and the ability to establish permanent settlements.
  • This shift toward settled life is especially evident in Mesoamerica.
• Regional focus: Mesoamerica
  • Mesoamerica extends from north of Panama to the desert of central Mexico and is characterized by great topographic, linguistic, and cultural diversity, yet shared features.
  • Common traits among early Mesoamerican civilizations include polytheism, blood sacrifice (ritual bloodletting and sacrifices of enemies), maize as a staple, and advanced calendrical and mathematical systems.
  • The Olmec are considered the mother culture of Mesoamerica; their influences shaped later Maya and Aztec civilizations.

The Olmec: The Mother of Mesoamerican Cultures

• Time and place
  • Flourished along the Gulf Coast of Mexico from about $1200 ext{ BCE} o 400 ext{ BCE}$.
• Economy and trade
  • Diffusion of culture through long-distance trade; key commodities included obsidian (weapons), jade (jewelry), feathers, and cacao beans (used to make a chocolate drink).
• Society and religion
  • Polytheistic; major deities included a rain god, a maize god, and the feathered serpent (Quetzalcoatl for the Aztecs; Kukulkan for the Maya).
  • Created an elite class through trade networks and exchange.
• Agriculture and diet
  • Maize, squash, beans, and tomatoes formed the basis of their diet; they also bred small domesticated dogs and consumed fish.
  • Aqueducts and irrigation supported city life and agriculture.
• Achievements
  • Built monumental architecture (e.g., La Venta pyramid) and giant head sculptures (Figure 1.4) ranging from 4 to 11 feet tall; some head weighs up to 50 tons.
  • Developed a long-distance trade system that contributed to political and economic power.
• Legacy
  • The Olmec laid the foundations for later Mesoamerican civilizations (Maya and Aztec) and influenced religious iconography and the concept of sacred serpents.
• Physical anthropology note
  • Olmec heads feature flat noses, slightly crossed eyes, and full lips, features still seen among some indigenous groups in the region.

The Maya and Teotihuacan

• Teotihuacan (central highlands) development
  • Flourished as a major urban center around 500 CE with population estimates exceeding 100,000.
  • Architecture and city planning:
  • Large-scale agricultural surplus allowed specialization beyond farming.
  • Built over 2,200 apartment compounds for multiple families and more than 100 temples.
  • Notable structures: Pyramid of the Sun (≈ $200 ext{ ft}$ tall) and Pyramid of the Moon (≈ $150 ext{ ft}$ tall).
  • Temple of the Feathered Serpent area with graves suggesting ritual sacrifice.
  • Trade linked Teotihuacan to Gulf Coast settlements.
• Maya civilization
  • Timeline: approx. $2000 ext{ BCE} o 900 ext{ CE}$; territory includes present-day Mexico, Belize, Honduras, and Guatemala.
  • Contributions
  • Calendrical and written language advancements; perfected a calendar and a writing/mathematical system.
  • Built city-states (Copán, Tikal, Chichén Itzá) along major trade routes and constructed temples, statues of gods, pyramids, and astronomical observatories.
  • Agriculture and urban planning
  • Surrounded by farms with primitive agricultural methods but achieved high population densities in city centers.
  • Decline
  • Environmental stress: poor soil and a multi-century drought contributed to decline around $900 ext{ CE}$; many large population centers were abandoned.
• Literacy and codices
  • The Maya developed a written system; Olmec influence contributed to their early writing.
  • Spanish contact and codices:
  • In the 16th century, Spaniards encountered Mayan glyphs preserved in folding books called codices (codex singular).
  • In 1562, Bishop Diego de Landa burned many codices in an attempt to suppress continuance of traditional practices; only a few survive today.
• Architectural and symbolic highlights
  • El Castillo (Figure 1.5) at Chichén Itzá served as a temple for the god Kukulkan; each side has 91 steps, totaling 365 steps when including the top platform (the number of days in a year).

The Aztec (Mexica) and Tenochtitlán

• Origins and urban foundation
  • Legend of emigration from Aztlán; by 1325, established Tenochtitlán on an island in Lake Texcoco.
• Size and grandeur by contact with Cortés
  • By 1519, population estimated over 200,000; the largest city in the Western Hemisphere at the time, possibly larger than contemporary European cities.
• Urban planning and daily life (as described by contemporary witnesses)
  • City featured organized neighborhoods for specific occupations, a trash collection system, markets, two aqueducts for fresh water, numerous public buildings and temples; Aztecs bathed daily and wealthy homes could have steam baths.
  • Built by a labor force of enslaved people from subjugated neighboring tribes.
  • Chinampas (floating gardens) irrigated by lake waters supported agriculture; vegetables grown included a variety of fertile crops.
• Interaction with the Spaniards
  • The Spanish, led by Hernán Cortés, encountered a highly complex and wealthy empire with extensive tribute from subject peoples.
• Aztec religion and sacrifice
  • Aztec religion involved many gods representing natural forces such as heaven, agriculture, rain, fertility, sacrifice, and war.
  • Central to religious life: ritual human sacrifice performed daily by a ruling class of warrior-nobles and priests to sustain the sun and support agricultural production.
  • Sacrificial method noted: removing the still-beating heart with an obsidian blade and discarding the body from the temple (Figure 1.7).
• Omens and prophecy
  • Moctezuma reportedly received omens and signs before the arrival of the Spaniards, including a fiery object in the night sky, an unextinguishable temple fire, a water spout on Lake Texcoco, and a wailing woman; these premonitions were recorded after the destruction of the Aztec world.

The Inca Empire

• Geography and scale
  • The Inca crown’s domain stretched along the Pacific coast and the Andes, spanning roughly $2{,}500 ext{ miles}$ from Colombia to Chile, with urban centers at altitudes up to $14{,}000 ext{ feet}$ above sea level.
• Infrastructure and administration
  • An expansive, well-maintained road system rivaling Roman roads; roads facilitated rapid movement of the Incan army.
  • No axle-mounted wheels; roads were stepped to navigate steep Andean terrain; runners called chasquis carried messages in relay.
  • Written language was absent; records kept via quipu (colored strings and knots) (Figure 1.8).
• Governance and economy
  • A centralized ruling class held absolute authority; the elite lived off peasants’ labor and accumulated wealth.
  • Mit’a system: peasants worked certain days per month on public works; in exchange, the ruler provided laws, protection, and famine relief.
  • Agricultural practices included terraced farming of maize, beans, squash, quinoa, and potatoes; the peasant share was typically one third; one third went to the ruler; one third was allocated for welfare.
• Religion and ritual
  • The sun god Inti was central; gold was considered the “sweat of the sun.”
  • Unlike Maya and Aztec, the Incas practiced relatively little human sacrifice; when sacrifices occurred, they tended to be prisoners and were reserved for emergencies (earthquakes, volcanoes, crop failure).
  • The ultimate sacrifice was children, who were well fed and believed to transition to a better afterlife.
• Machu Picchu
  • Discovered in 1911 by Hiram Bingham; located about fifty miles from Cusco, at ~$8{,}000 ext{ feet}$ above sea level; built around $1450 ext{ CE}$ and abandoned roughly a century later.
  • UNESCO designated Machu Picchu a World Heritage Site in 1983; construction featured precisely cut polished stones without mortar, demonstrating advanced masonry.

Native Americans: Diversity and Distribution in North America

• General pattern
  • North American Native cultures were widely dispersed and generally less population-dense and less politically centralized than Mesoamerican civilizations.
  • While some groups adopted horticulture and agriculture, many communities continued hunting and gathering, especially in less favorable environments.
  • The arrival of horses by the Spanish transformed Plains-based hunting for bison and altered mobility and social organization.
• Distinct regional groups and notable societies
  • Pueblo peoples of the Southwest: Mogollon, Hohokam, and Anasazi (Ancestral Puebloans)
  • Mogollon (c. 150 BCE–1450 CE): distinctive black-on-white geometric pottery depicting birds and other motifs.
  • Hohokam (c. 600 CE onward): extensive canal irrigation systems; red-on-buff pottery; turquoise jewelry; supported large populations by desert agriculture (corn, beans, squash).
  • Anasazi (ancient enemies/ancient ones): cliff dwellings with rope ladders; canyon networks; 180 miles of roads linking pueblos to Chaco Canyon (the regional hub by 1050 CE).
  • Decline and abandonment around 1300 CE, likely due to drought; descendants include Hopi and Zuni.
  • Eastern Woodlands and Cahokia (Mississippi River valley)
  • Hopewell culture (Ohio River Valley, 1st–4th centuries CE): small hamlets; wattle-and-daub houses; extensive trade networks from Canada to Louisiana; shells, copper, obsidian; monumental burial mounds and earthworks indicating social stratification.
  • Cahokia (near present-day St. Louis): large urban center (around 1100 CE) covering ~5 square miles with 120 earthen mounds; a hub for political and trading activity along the Mississippi; population over 10,000 with tens of thousands more in surrounding farms; decline after 1300 due to resource limits.
  • The Phoen (Northeast and Southeast groups) and Iroquoian, Algonquian, and Muskogean speaking communities
  • East of the Mississippi, many small autonomous clans or tribal units; regular warfare as groups vied for territory and resources.
• Social organization and gender roles
  • Many eastern tribes practiced matriarchy or matrilineal transitions on social authority; women often cultivated crops and influenced leadership, while men hunted and protected communities.
  • Gender roles were complementary, with both parents sharing child-rearing responsibilities.
  • European contact disrupted these social arrangements, often imposing patriarchal European norms and private land ownership concepts.

Land, Ownership, and European Contact: Conflicting Worldviews

• Private land ownership vs communal land use
  • For many Native groups, ownership of land did not follow a private-property model; land was a communal resource and tied to community use and stewardship.
  • By contrast, the European Christian worldview framed land as wealth and property to be owned, exploited, and commercialized, with a divine mandate to subdue nature (Bible-based justification).
• Cultural clash and environmental ethics
  • The clash over land ownership and environmental use became a major source of conflict as Europeans expanded into Indigenous territories.
  • These differing worldviews contributed to long-term tensions about land rights, resource use, and sustainability.
• Summary context
  • The Spanish encounters with the Maya, Aztec, and Inca revealed complex urban civilizations and sophisticated agricultural, architectural, and religious systems.
  • In North America, disturbance by disease and later colonization led to shifts in demographics and social organization, with enduring legacies in culture, land use, and governance.
