Bavarii

The Bavarii were a Germanic tribe whose name emerged late in Teutonic tribal times. The full name originally was the Germanic *baio-warioz. This name has been handed down as Baiwaren, Baioaren, Bioras, latinised Bavarii, Baioarii. or Bavarii, Bavarians, Bajuwaren, Bajuvarii, Bajuwaren and Baiern. It is assumed that this is an endonym. The first part "baio" refers to the name of the Celtic Boii tribe, which also resolved into the regional name Bohemia (Germanic latinised boio-hemum = home of the Boier tribe). Bavaria is geographically the same region as the Böhmer Wald (forested hill slopes). With the arrival of northern Gothic people, particularly the Scirii in the then Roman province of Pannonia by 493 a soundshift changed Boi to Bai (Bajuwari). The land remained under the name of Bohemia and part of the Holy Roman Empire even when centuries later Czech people moved to the area.
