Pre-Columbian Native American Civilizations

Jun 28, 2025

Overview

This lecture covers the history of Pre-Columbian America, focusing on the origins, cultures, and civilizations of Native Americans, especially the Cahokia civilization.

Origins and Migration of Native Americans

  • Native Americans (Amerindians) arrived via the Beringia land bridge connecting Siberia to Alaska around 20,000 years ago.
  • Beringia was a grassland during the Ice Age, not covered by glaciers.
  • Paleo-Indians settled Beringia, then spread across North and South America by following herds of large animals.
  • The Clovis culture, known for distinct stone tools, was once thought the earliest, but older sites have been found.
  • Genetic and linguistic studies connect Native Americans to Siberian peoples.

Agricultural Revolution and Major Civilizations

  • Maize (corn) was domesticated around 5000 BC, enabling population growth and complex societies.
  • The Aztecs, Mayans, and Incas built advanced cities with writing systems, astronomy, and trade networks.
  • Maize cultivation led to urban centers and social hierarchies.

Native Cultures in North America

  • North America had hundreds of tribes with diverse languages and constantly shifting territories.
  • The Hohokam in the Southwest built irrigation canals and temple-like structures.
  • The Anasazi (Ancestral Puebloans) built cliff dwellings and extensive road networks; they abandoned their sites in the late 1200s due to drought or conflict.
  • Pacific Northwest cultures were hierarchical, practiced slavery, and held potlatch feasts despite lacking agriculture, thanks to abundant natural resources.
  • Plains Indians were nomadic buffalo hunters; their lifestyle changed dramatically after horses arrived with the Spanish.
  • Eastern Woodlands tribes (Algonquian, Iroquoian, Muskogean) organized by village, led by chiefs, practiced patrilineal or matrilineal kinship.

Mound Builders and Cahokia

  • Mound builders constructed earthen mounds for burial or ceremonial purposes across North America for 5,000 years.
  • Early examples include Watson Break and Poverty Point in Louisiana.
  • The largest and most complex mound-building society was Cahokia (700–1300 AD) near present-day St. Louis, IL.
  • Cahokia had up to 20,000 residents, massive trade networks, and social hierarchies.
  • Monk's Mound is the largest mound north of Mexico and served as a religious and political center.
  • Cahokia featured Woodhenge (astronomical wooden circles), evidence of human sacrifice, and an elite "Birdman" burial.
  • Decline of Cahokia may have resulted from environmental problems, warfare, or food shortages.

Preservation and Repatriation

  • The Native American Graves Protection and Repatriation Act (NAGPRA) of 1990 requires the return of Native remains and sacred objects to descendant tribes.
  • Destruction of archaeological sites (e.g., Slack Farm) led to stronger legal protections for Native heritage.
