The Inca people played very well tactically and through peaceful manner little by little were managing to unify the different people they have conquered and ruled over them. The Inca rulers were unifying the diverse people by making one language as official language of the Empire, making good infrastructure that was connecting all parts of the empire and thus allowed the people to integrate, they encouraged people to believe in their sun god Inti which made the empire religiously monogamous, and also the four regions of the empire had their own regional rulers, but all of them were under the command of one unifying Emperor which was also considered as deity.
It did in the long run. In the short run it created many issues because there was a rise in extremism, in southern states especially. For starters, racists didn't want to desegregate their schools and public places so they didn't enforce the decision of the court throughout the entire next decade. Another thing is that organizations that were illegal like the Ku Klux Klan started getting power and harassing innocent African-Americans. It did create a litigious environment however because suddenly there were many more cases regarding desegregation and they had the court's precedence support so they were easily won because of the way the legal system works. It didn't lack legal justification, the only problem was enforcing it before the civil rights acts were passed and the country started battling racism systematically in all of the United States.

So the just the massive scale of the migration was what overwhelmed the other tribes.
