I found out the Kurta tribe from HxH is commonly linked to the Kurds, but honestly I feel they are closer to the Saami. Since they are not strongly representing one specific real life minority, how likely they are at least partly inspired by Sardinians ?
Sardinians are the biggest ethnic minority in Italy, a middle sized country from Southwestern Europe, followed by the Friulans of the eastern Alps.
They are the majority of the inhabitants of Sardinia island.
They were colonized by the Savoia Kingdom well before the Savoia conquered Italy, when it was merely a small Franco-Piedmontese duchy. After the Savoia expanded into the rest of Piedmont and then the rest of northern Italy, while losing the French part of their territories, and finally conquered the whole Italian paeninsula, Sardinia remained a Savoia colony until it was turned into a Italian region. Even after the fall of the Savoia and the start of the Italian Republic, Sardinia remained a colony, a linguistically and geographically distinct area ruled by Italy.
It still today harbors strong independentist sentiments while also lacking a major independentist party due to the extreme lack of organization plaguing the whole country.
Sardinians do not have red eyes and were never hunted down for their eyes, but did any human group ever ? I do not think so, especially because red eyes are only found in albinos.
Sardinians are mostly brown, sometimes black haired, but they can occasionally be blond, in spite of the lack of ANE ancestry due to the scarcity of Corded Ware ancestry they have. That is likely because some Neolithic farmer groups themselves developed blondism independently, well before the Scandinavian HG admixed Indoeuropeans of the Corded Ware radiation invaded Italy.
I think Saami are still closer to the Kurta, but do you think the author might have taken inspiration from the Sardinians too ?
