could be used for both cutting and thrusting. The gladius replaced the more pointed, blunt-edged swords that Romans had used until the 3rd century BCE. There are several theories regarding this, including the idea that the gladius was introduced by Celtiberian tribes in the Iberian Peninsula, by Celtic or Celtiberian mercenaries fighting for Hannibal in the Second Punic War, or by Gallic tribes in Europe.

The later adoption of the spatha, a longer sword than the gladius, was largely due to the increasing numbers of Celtic cavalry auxiliaries in the 2nd to 3rd century CE Roman army, and changes in Roman tactics. Other examples of Celtic arms adopted by the Romans are the Montefortino and Coolus helmet-types.
