Pekka Hemalainan is pretty much the only historian who studies native tribes during the European colonization. His recent book talks about how the tribes didn't view Europeans as much of a challenge or difficulty. The loss of land came from their own arrogance than anything to do with the idea of European dominance.
Basically, European colonies survived by going to places the other tribes didn't consider important. Another tribe had died off, and the Europeans settled in that land? Sure go ahead.
This follows similar ideas in business tech called Disruption. Nintendo has specifically tried to emulate the ideas from books based on those studies. They let Sony and Microsoft battle for the same players, and then offer it to everyone else, with a few games those other players might enjoy as well.
I bring this up because the same ideas are being used to promote the 'great replacement'. The POC are not that important, but they should be given all this power because they aren't a threat.
Most European settlers in the U.S. and Canada came into land that had been devastated by disease. Indian numbers were no threat. The lands they colonized were either considered cursed/diseased or were off-season grounds for tribes that stood no chance due to lack of numbers. The Iroquois League had been a recent formation by the time white settlers came because of this power vacuum.
It was only just burning through South America when the Inca were conquered. And most of them were killed by native tribes they had oppressed and joined the Spanish starting with the Maya and Aztecs. That's why most latinos in the Americas don't look white, they're not. Even in Mexico. They might have a little white in them, but they are mostly native Indians. It's the opposite of white americans. What's funny is, there are groups of white Latinos in those countries who are almost exclusively Spaniard or Spaniard/French/English background because they are descended from the aristocracy and refused to breed with common stock. Don't forget the white descendants of merchants, prisoners, wrecked colonial vessels, slave traders, sailors, expats., the list goes on. Then there are the losers of various wars, like the Southerners from the U.S., exiled French, Portuguese nobles, the Germans. All of them are white and most speak Spanish or Portuguese. All of them settled in areas where there was no more natives because of disease or war.
I descend from those German colonists in Argentina. There was a caste system based on complexion for a long time.
