Considering this, why did Cahokia disappear?
The flood sediment marks a significant decrease in the amount of pollen, indicating that farming at Cahokia almost completely collapsed after the flooding. Munoz believes the return of flooding caused or at least contributed to the abandonment of Cahokia.
Also, why did the Mississippians disappear? The rapid decline may have been caused by an earthquake, or warfare. Whatever the explanation, it meant that by the time European settlers began moving into the region in the 18th and 19th centuries the American Indians they met were migrants like themselves.
Similarly one may ask, what happened to the Cahokia civilization?
After reaching its population height in about 1100, the population shrinks and then vanishes by 1350. Perhaps they had exhausted the land's resources, as some scholars theorise, or were the victims of political and social unrest, climate change, or extended droughts.
What is Cahokia and why is it historically significant?
Covering more than 2,000 acres, Cahokia is the most sophisticated prehistoric native civilization north of Mexico. Best known for large, man-made earthen structures, the city of Cahokia was inhabited from about A.D. 700 to 1400.
