One thing you find in the Americas, is that many tribal groups considered themselves (and their names for themselves show this), "The True People", "The Real Humans", and others were something less, of course. You could do all kinds of nasty things to those who were less than human. The House of Valois and the House of Plantagenet were both the same French people (who just happened to be running England), and both Christian. The were just arguing about who should be King. In another 100 or 200 years when religious wars started in Europe, THEN those from another religion could be wiped out - whole towns full of them if you felt like it.
The other thing this reminds me of is the tragic legend of the two lovers Popocatepetl and Iztaccíhuatl, who, if I remember correctly, were Tlaxcaltecas, enemies of the Aztecs. I won't go into all the details, but the beautiful Iztaccíhuatl falls in love with the warrior Popocatepetl. Her father, the chief agrees to let them be married, as soon as Popocatepetl returns victorious from a battle (that the chief is sure he will be killed in). When he doesn't return when expected, the chief tells his daughter that Popocatepetl has been killed. Iztaccíhuat promptly dies of grief when she hears this. Almost immediately, Popocatepet shows up, having won a great victory, and then finds out what has happened. He is simultaneously filled with grief and anger. He carries Iztaccíhuatl's lifeless body into the mountains to restore her life, but it doesn't work, but Popocatepetl and Iztaccíhuatl are transformed into snow-covered volcanic mountains, and their pictures show up in Mexican restaurants across the Western Hemisphere.
There were also transformed into a fox and a wolf, who appeared as background art in the movie *Zootopia* for just a few seconds, to be noticed by people like me who pay attention to tiny insignificant details:

[EDIT] Found it.

It was on the side of Finnick's van, in the scene just after the "baby fox and his dad" scam, You can see it as Finnick leaves and says "If you kiss me tomorrow, I'll bite your face off! Ciao!"
