No one in Europe is really “pure”.
In Italy’s case people often overrate the fact that different parts of the peninsula had different rulers as an evidence, but that accounts to little.
The point is that in the Late Roman Empire the genetics of Italy changed a lot because of the Empire’s internal migrations, and that didn’t change much over the centuries after the fall of Rome, as foreigner rulers were mostly an elite minority that ended ep being assimilated.
See the Franks, they managed to give their name to France, but they ended up being assimilated by the much more large romance people (same case in Lombardy).
Despite that Italians still retains much of the Neolithic genetics (Italo-Celtics).
Italian identity is mostly a cultural thing though, but that’s the idea behind every European National States.
