The Germanic peoples (also called Teutonic in older literature) are a historical ethno-linguistic group, originating in Northern Europe and identified by their use of the Indo-European Germanic languages, which diversified out of Common Germanic in the course of the Pre-Roman Iron Age. The descendants of these people contributed to ethnic groups in North Western Europe: Scandinavians (Danes, Swedes, Norwegians, Icelanders, and Faroe Islanders, but not Finns and Sami), Germans (including Austrians, German-speaking Swiss, and other ethnic Germans), Dutch, Flemish, and English, among others.
Migrating Germanic peoples spread throughout Europe in Late Antiquity (300-600) and the Early Middle Ages. Germanic languages became dominant along many western European Roman borders (Austria, Germany, Netherlands, Belgium and England), but in the rest of the western Roman provinces, the Germanic immigrants eventually adopted Latin (Romance) dialects. All Germanic peoples were eventually Christianized.
In late Roman times, Europe's Germanic peoples, such as the Franks, Saxons, Vandals, Angles, Lombards, Suebi, Burgundians and Goths, divided up the Western Roman Empire, and transformed it into Medieval Europe. Today Germanic languages are spoken through much of the world, represented principally by English, German, Dutch and the Scandinavian languages.
