Cato (Cato the Elder), knowing the bad relations between Suessetani and Iacetani, took this to Roman advantage and managed to gain their support for the Roman conquest of the Iacetani territory and their capital, Iaca (Jaca), in 195 BCE. So the Suessetani, at the beginning of the 2nd Century BCE, were Roman allies, but some years after they rebelled and resisted against Roman expansion, an action that had terrible consequences for the Suessetani as a tribe with his own identity. Because of this, their territory and capital was taken by a Roman army on the orders of the governor of Hispania Citerior, Aulus Terentius Varro, in the year 184 BCE. Corbio, the capital, had to be taken using siege weapons and was destroyed after that siege. Assimilation by the Vascones The Vascones, that dwelt to the northwest of the Suessetani, in alliance with the Romans and with Roman incentive, took advantage of the Suessetani defeat, they took Suessetani lands and assimilated most of them in the middle and the end of the 2nd century BCE. The Suessetani ceased to exist as a different tribe with his own identity. When later authors such as Strabo and Ptolemy wrote their works (in the 1st century BCE and 1st century CE), the Suessetani had already been assimilated by the Vascones, as they don't mention them. They describe the Suessetani former territory as a vasconian one. Partially because of this, Suessetani are sometimes ignored as a different tribe or wrongly classified as a tribe of the Vascones or the Iberians.
