1. The Population Question and Why It Was So Contested
At the heart of the older narrative was the assumption that the Americas were sparsely inhabited before Europeans arrived. Mann traces how this assumption was never just a neutral empirical claim but was shaped by ideological convenience, since a nearly empty land was easier to justify colonising. Scholars who argued for much larger pre-contact populations faced fierce resistance for decades, even as the evidence from burial sites, settlement patterns, and historical accounts continued to accumulate in their favour. The debate has never fully resolved into a single agreed figure, and Mann is candid about that uncertainty, but the direction of revision has been consistently upward, with estimates for some regions running into the tens of millions.
Why it matters: The population question is not an antiquarian puzzle. How many people lived in the Americas before contact determines how we understand the scale of what was lost, and it shapes every subsequent argument about land, sovereignty, and historical responsibility.
