Numantine War
The Numantine War (from "Bellum Numantinum" in Appian's "Roman History") was the last conflict of the Celtiberian Wars fought by the Romans to subdue those people along the Ebro. It was a twenty-year conflict between the Celtiberian tribes of Hispania Citerior and the Roman government. It began in 154 BC as a revolt of the Celtiberians of Numantia on the Douro. The first phase of the war ended in 151, but in 143, war flared up again with a new insurrection in Numantia.
