The Raeti and the Vindelici tribe have a very curious history. The Raeti spoke, according to some sources, a variant of Etruscan, though some of the words are cognates of Celtic, perhaps evident of some Celt migration through the area. It was hypothesized that the Raeti were Etruscan peoples that survived the Celtic migrations by fleeing to the Alps, but its also probable that they are simply an Etruscan people that settled there long before and continued to live for centuries after the Celts overran most of the Etruscan presence in northern Italy. The Vindelici, their close northern neighbors, spoke a language that is either Venetic or Lepontic Celt. The surviving records only mention a handful of tribes by name. As a frontier province with Germania, as was Noricum, the area was neglected for two centuries after the Romans annexed them.
The Norici, aka the Taurisci, were the leaders of a federation of twelve tribes that the Romans actually called a proper kingdom and called it Noricum. Noreia today still has not been conclusively found. They had a presence unique within the empire because they were still ruled by semi-independent kings until Antoninus Pius.
