Iacetani

The Iacetani were defeated by the Romans in 195 BC when Cato the Elder took their capital with the support of the Suessetani, which distracted the Iacetanian army.

Julius Caesar cited the Iacetani as one of the tribes that changed allegiances to him alongside the Ausetani and Illurgavones during his campaign extending the Roman frontier.

[2] This event happened shortly after Decimus Brutus defeated Domitius' fleet in the war against the Veneti and increased Caesar's reputation among the natives prompting the Iacetani to begin sending envoys and even agreed to supply him with corn.

[3] In 19 BC their territory was incorporated into the Roman Empire, in the aftermath of the Cantabrian Wars, as vassals of Rome.

This meant that they did not enjoyed the full Roman citizenship status, and their situation was precarious when compared to other peoples of the region, such as the Sedetani.
