Is it true that indigenous North Americans engaged in extensive inter-regional trade networks prior to European contact?
Yes. Archaeological evidence demonstrates that Indigenous North Americans maintained extensive long-distance trade and exchange networks long before European contact.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The analysis
Papers 1, 5, and 8 all directly support the claim by providing archaeological evidence of precontact trade and exchange networks across North America (such as the diffusion of maize via exchange networks, earthworks used for intergroup exchange, and pre-Columbian copper trade). No papers refute the claim.
