Research suggests Aztalan (~500 people) was a Mississippian colony linked to Cahokia. Around 1050 CE, Cahokia rebuilt itself as a major city with trade networks stretching from Oklahoma to Georgia. Long-nose ear ornaments found at Aztalan match those from Cahokia and Spiro, hinting at direct cultural ties 🏺
