Celtiberia
Celtiberia, the region spreading across the centeral highlands of Iberia. Neither Celtic, nor Iberian, the Celtiberians were a complete blending of the two cultures. The people of Celtiberia wore torques with Iberian design. The warriors used the famous Iberian swords will keeping their traditionaly Celtic shields. This fusion of culture didnt not happen over night. Infact, it only occured after several bloody wars. Surronded by foreign peoples the Celtiberians had to fight to surive. Their capital at Numatania was some of the best natural defenses that any city would ever be able to claim. From here the Celtiberians would go off to far away lands to serve as mercenaries to the highest bider.
Their language was distinctally Celtic. Not the Celtic of Gaul, but of a much older stock, which meant that Celtiberians would have a hard time communicating with the Gallic cousins. To frustration of modern historians the Celtiberians used Iberian script to write, which uses letters to spell syallables. This can mean for very hard translating as the same letter can mean many things. In latter times the Celtiberains would adopt Latin script which would prove much more effective.
Little is known of the Celtiberians. One thing we know is their contemporaries noted their great hospitality. However, they were also fierce fighters. While Rome would conquer the rest of Iberia, Celtiberia would remain a thorn in her side. The siege of Numatania took a whole of nine years, in which many Roman generals would head back home with their tail between their legs. Only when 60,000 romans besieged the meger defense of 8,000, could the Romans finally defeat their troublesome enemies.
Though Celtiberia had fought very hard for her indepence, conquest by Rome was inevitable. Sharing a similiar phate to the rest of Iberia, Celtiberia would become heavily romanized, and as a result the Celtiberian culture would become extinct, in sharp contrast to the Galatians who maintained their ways till the end.
