When The Romans defeated the Carthaginians in The Second Punic War, they drove most of The Celts back over The Alps, and destroyed their settlements. Then, they colonised the entire northern Italian region with Italic tribesmen and Romans, whom, after several generations, completely Italianized Northern Italy. Then, centuries later, when The Lombards came into Italy, they dispersed to other parts of the penninsula, including The South, and Southern Italy and Northern Italy absorbed them into their populations. The fact is, Southern Italians and Northern Italians are THE EXACT same ethnic people whether anyone wants to admit it or not. The Romans that defeated The Tuetons and The Cimbri were Sabine and Samnite, Latini, and all the other Italic Tribes that Marius recruited in his home region inland from Roma. Then, all the soldiers Julius Caesar recruited to defeat The Germans and Celts of Northern Europe were The same Italian tribesmen as them, and, we modern Italians descend from these tribes. Or, at least most of our genes and blood from that period of our lineage comes from them. Northern Italians are completely errant if they believe they have any right to suggest racial superiority over their Southern countrymen. It's completely ridiculous.
They are not German nor Celtic - they are Italian.
