Celtic
Celtas is the term used by linguists and historians to describe, in a broad sense, the people or group of peoples of the Iron Age who spoke Celtic languages, one of the branches of the Indo-European languages. In this sense, the term is therefore neither ethnic nor archaeological, since many of the peoples who spoke Celtic languages, in the case of the Goidelos of Ireland, never came to participate in the material cultural currents of Hallstatt or La Tène. There is, however, a more restricted concept of the term, referred to in this case as the so-called historical Celts, traditionally understood as the group of European tribal societies, who shared a material culture initiated in the first iron age around the Alps and Later in the late iron, and which were thus called by the Greek and Latin geographers. In this group the continental Celts of Gaul, northern Italy, Germany and Bohemia, the Celtiberians of Iberia, the Galatians of Anatolia, east and center of Romania, and with greater reluctance by British and Irish historians the Celtic islanders are ascribed.
