East Germanic

The tribes referred to as East Germanic constitute a wave of migrants who moved from Scandinavia into the area between the Oder and Vistula rivers between 600 - 300 BCE. In historical times these tribes were differentiated as Goths, Burgundians and Vandals among others. The East Germanic languages shared many characteristics and are more closely related to North Germanic than West Germanic because of a later migration date. All the East Germanic languages are extinct.
