Page "Archbishopric of Salzburg" Paragraph 7

From the 6th century onwards, the northern parts of the later archbishopric were resettled by Germanic Bavarii tribes, who established themselves among the remaining Romance population, while Slavic tribes moved into the southern Pongau and Lungau parts.

About 696 Saint Rupert, then Bishop of Worms in Frankish Austrasia and later called the apostle of Bavaria and Carinthia, came to the region from the Bavarian capital Regensburg and laid the foundations for the re-establishment of the Salzburg diocese.

After erecting a church at nearby Seekirchen he discovered the ruins of Iuvavum overgrown with brambles and remnants of the Romance population, who had maintained Christian traditions.

The former theory that he arrived already in c. 543 during the time of the unsourced early Bavarian dukes appears less likely than that he worked during the reign of the Agilolfing duke Theodo II ( c. 680 – 717 ), when the Bavarian stem duchy came under Frankish supremacy.

In either case, it was not until after 700 that Christian civilisation re-emerged in the region.
