The Germanic tribes referred to as East Germanic constitute a wave of migrants who may have moved from Scandinavia into the area between the Oder and Vistula rivers between the years 600 and 300 BC. Later they went to the south. Unlike the Northern and Western tribes, they did not successfully preserve their ethnicity and were primarily assimilated into West Germanic tribes and Romans.

The Germanic peoples (also called Teutonic, Suebian or Gothic in older literature) are an Indo-European ethno-linguistic group of Northern European origin, identified by their use of the Germanic languages which diversified out of Proto-Germanic starting during the Pre-Roman Iron Age.
