Historians have identified Gothiscandza as northern Poland. Note the similarity between the words Gothiscandza and Gdansk, the port city of modern Poland.
When was this migration? Extant data suggest that the Goths crossed the Baltic Sea circa 300 B.C. inhabited the Polish territory during the 1st century A.D, and then Scythia during the 2nd century A.D.
The Goths maintained their sub-tribe names from their time in Sweden: the Ostrogoths being the eastern tribe and the Visigoths the western. After the migration, he Ostrogoths occupied the area north of the Black Sea while the Visigoths occupied the area of the Balkans (Dacia).
