One of the most distorted perceptions of history is that the Native Americans all lived in tipis and tribes and had only the most basic weapons and technology. Many in what is now in the United States and Canada did live that way. But not in Mexico. When first Europeans came, they had built some of the greatest cities and empires in history, which only fell to European diesease and superior weaponry. Tenochtitlan, the Aztec capital, was five times bigger than London at the time. In the south USA, many Indians like the Pueblos had already gone past living in tribes, and had formed towns.
My question is; WI the technological progress of the Incas and Aztecs and the like was such that when the first Europeans arrived, they found a foe who could match or even surpass them in technology? Let's take this a step further, and say the Europeans' dieseases were also in North America at the time, so the Natives had already developed immunity. Want to go even further? Lets say the Indians who did live in tipis and tribes also banded together and built empires. Imagine a Cherokee or a Comanche Empire. Since the Pueblos were already urban, I can easily imagine a Pueblo Empire.
How does everyone think the course of history would be affected? Do the Native Empires never fall and are still international players today? Are the Europeans allowed to settle peacefully? And how do major world events such as WWII play out?
