Under the Byzantine Empire

When Rome split in 395 AD, Albania became part of the Byzantine Empire. Under this rule, Illyria suffered devastation by barbarian raiders including the Huns, Visigoths, Ostrogoths, Slavs, etc. Only the southern tribes (modern day Albania), preserved their native language and culture amidst Slavic assimilation. During this period, the name of the region changed from Illyria to Arbri and finally to Albania (after the Albanoi tribe which inhabited that region).
