What is "gallaeci"

The Gallaeci or Callaeci were a large Celtic tribal federation who inhabited Gallaecia, the north-western corner of Iberia, a region roughly corresponding to what is now Galicia (Spain), northern Portugal and Western Asturias, before and into the Roman period. They spoke a Q-Celtic language related to Northeastern Hispano-Celtic, usually called Gallaic, Gallaecian, or Northwestern Hispano-Celtic.

The region was annexed by the Romans in the time of Caesar Augustus during the Cantabrian Wars, a war which initiated the assimilation of the Gallaeci into Latin culture.
