late edit: DISCLAIMER: The pictured map is not actually a representation of the territories before colonisation. It’s a hypothetical map of what countries there might have been had the continent not been colonised, thus all the names and borders are fictional and have never existed.
For good actual maps, check out native-land.ca.
That was me. Grew up thinking that one of my great grandparents was full blooded Cherokee. Took a DNA test only to find out that my DNA only had like 1 or 2 percent Native American DNA.
