The Iberians were an ancient Hispanic people in the Iberian peninsula which has parts of modern day Spain, Portugal, Andorra, and part of France. The Iberians were greatly influenced by the Romans and Phoenicians. They traded with Carthage and were also hired as mercenaries in the Carthaginian Military.
They are known for their light infantry soldiers called Caetrati who were equipped with either a short sword or a spear (and also had a shield of course) and were good at ambush attacks and scouting.
The Iberians also mixed with Celtic tribes, Celtic and Iberian mixed tribes were called Celtiberians.
