Cisalpine Gaul
Isn’t modern Tuscany part of what the Romans called “Cisalpine Gaul”? If I’m right, that would sorta indicate that the Gauls from over the alpines displaced the bronze age inhabitants.
also wonder how much german immigration occurred in the area in the late empire. I would assume they might be able to link current/medieval dna of the area to other historical dna of known groups that have migrated.
Cisalpine Gaul
No, the southern boundary of Cisalpine Gaul was the Rubicon river, which is why when Caesar took his army out of his province by crossing the Rubicon he had declared war on the Senate of Rome.
