Main article: History of Bavaria

The Bavarians emerged in a region north of the Alps, originally inhabited by the Celts, which had been part of the Roman provinces of Rhaetia and Noricum. The Bavarians spoke Old High German but, unlike other Germanic groups, did not migrate from elsewhere. Rather, they seem to have coalesced out of other groups left behind by Roman withdrawal early in the 6th century AD. These peoples may have included Marcomanni, Thuringians, Goths, Rugians, Heruli, and some remaining Romans. The name "Bavarian" ("Baiuvari") means "Men of Baia" which may indicate Bohemia, the homeland of the Marcomanni. They first appear in written sources circa 520. Saint Boniface completed the people's conversion to Christianity in the early 8th century. Bavaria was, for the most part, unaffected by the Protestant Reformation, and even today, most of it is strongly Roman Catholic.

From about 550 to 788, the house of Agilolfing ruled the duchy of Bavaria, ending with Tassilo III who was deposed by Charlemagne.

Three early dukes are named in Frankish sources: Garibald I may have been appointed to the office by the Merovingian kings and married the Lombard princess Walderada when the church forbade her to King Chlothar I in 555. Their daughter, Theodelinde, became Queen of the Lombards in northern Italy and Garibald was forced to flee to her when he fell out with his Frankish overlords. Garibald's successor, Tassilo I, tried unsuccessfully to hold the eastern frontier against the expansion of Slavs and Avars around 600. Tassilo's son Garibald II seems to have achieved a balance of power between 610 and 616.

After Garibald II little is known of the Bavarians until Duke Theodo I, whose reign may have begun as early as 680. From 696 onwards he invited churchmen from the west to organize churches and strengthen Christianity in his duchy (it is unclear what Bavarian religious life consisted of before this time). His son, Theudebert, led a decisive Bavarian campaign to intervene in a succession dispute in the Lombard Kingdom in 714, and married his sister Guntrud to the Lombard King Liutprand. At Theodo's death the duchy was divided among his sons, but reunited under his grandson Hucbert.

At Hucbert's death (735) the duchy passed to a distant relative named Odilo, from neighboring Alemannia (modern Southwest Germany and northern Switzerland). Odilo issued a law code for Bavaria, completed the process of church organization in partnership with St. Boniface (739), and tried to intervene in Frankish succession disputes by fighting for the claims of the Carolingian Grifo. He was defeated near Augsburg in 743 but continued to rule until his death in 748.

Tassilo III (b. 741 - d. after 794) succeeded his father at the age of eight after an unsuccessful attempt by Grifo to...
