Wow - 20000 inhabitants in the city in 1150 AD. I did not realize this. I always pictured migrating bands of tribes back then in America not a big city. Very interesting. Learn something every day.

There were a few migrating bands of tribes but they were the minority. The majority were farmers who did some hunting.

There were several cities in North America but it was mostly large villages on the East Coast.

Lacking large domestic animals for protein large cities were mostly not practical.

I could be wrong here but a small town of 20000 by 1150 A.D. was not much to get excited about, considering the large cities that existed in various places and times B.C. throughout South and Central America. There is a pyramid in SA (Peru?) that is not only much older, but much larger than the Great Pyramid in Giza, Egypt.
