 During the time of Attila in the 5th century the entire Middle Danube region saw the entry of many new peoples from north and east of the Carpathians, and the formation and destruction of many new political entities.It is thus more probable that the Baiuvarii emerged in the provinces of Noricum ripense and Raetia secunda following Odoacer's withdrawal of population to Italy in 488, and the subsequent expansion of Italian Ostrogothic, and Merovingian Frankish influence into the area.They are believed to have incorporated elements from several Germanic peoples, including the Scirii, Heruli, Suebi, Alemanni, Naristi, Thuringi and Lombards.
