Final answer:
Historians conclude that the Mississippian peoples were highly organized, facilitating the construction of large urban settlements like Cahokia, with mounds serving religious, burial, and administrative purposes, and maintaining vast trade networks.
Step-by-step explanation:
Based on the evidence of Cahokia, historians might conclude that the Mississippian peoples had significant social organization, which allowed them to coordinate the construction of large buildings.
The creation of large urban settlements, such as Cahokia, with its complex mounds and urban centers, indicates a structured society capable of large-scale projects. These mounds were used as temples, burial sites, and centers for political administration, reflecting a hierarchy and the centralization of leadership within the community.
The artifacts and traded goods found indicate that they also maintained extensive trade networks, demonstrating another aspect of a highly organized society.
