Question: Where did the Celtiberians live??
Answer:
Where did the Celtiberians live?
The Celtiberians were a group of Celts or Celticized peoples inhabiting the central-eastern Iberian Peninsula during the final centuries BC. They were explicitly mentioned as being Celts by several classic authors (e.g. Strabo[1]). These tribes spoke the Celtiberian language and wrote it by adapting the Iberian alphabet.[2] The numerous inscriptions that have been discovered, some of them extensive, have allowed scholars to classify the Celtiberian language as a Celtic language, possibly one of the Hispano-Celtic (also known as Iberian Celtic) languages that were spoken in pre-Roman and early Roman Iberia. Archaeologically, many elements link Celtiberians with Celts in Central Europe, but also show large differences with both the Hallstatt culture and La Tène culture.
