<P> The Great Migration (Völkerwanderung) sealed the decline of Roman power in Austria . In the First Phase (300--500 AD) the Roman Empire was increasingly harassed by Germanic tribes from the 5th Century, including Goths and Vandals . As the fabric of the Roman Empire crumbled, the ability of Raetia, Noricum and Pannonia to defend themselves became increasingly problematic . Radagaisus overran part of the country in 405 . (Géza Alföldy pp. 213--4). After several raids on Italy, the Visigoths arrived in 408, under Alaric I . </P> <P> As described by Zosimus, Alaric set out from Emona (modern Ljubljana) which lay between Pannonia Superior and Noricum over the Carnic Alps arriving at Virunum in Noricum, as had been agreed to by the Roman general Stilicho, following several skirmishes between the two . Alaric was voted a large amount of money to maintain peace, by the Roman Senate, at Stilcho's instigation . From there he directed his operations against Italy, demanding Noricum among other territory, finally sacking Rome in 410 but dying on the route home that year . </P> <P> The Visogoths eventually moved on, allowing a short period of stability apart from domestic disturbances in 431 . (Alföldy p. 214). 451 saw the Huns pour through the land, and in 433, Pannonia had had to be evacuated under the Hun attacks . The death of Attila in 453 allowed the Ostragoths to scatter his Hunnish empire . Many tribes, formerly under the Huns now started to settle along the Danube basin and assert their independence . Among these were the Rugii, who formed their own lands (Rugiland) across the Danube and started to impose their will on Noricum . </P> <P> From 472 Ostrogoths and Alamanni invaded the area but did not subdue it . Even after Odoacer had overthrown the last Western Roman Emperor in 476, there remained remnants of the Roman administration in the provinces before the final collapse of Late Antiquity in this area (see Severinus of Noricum and Flaccitheus). Noricum was eventually abandoned in 488, while Raetia was abandoned by the Romans to the Alamanni . </P>
