The first Archbishop of Salzburg, and the man who put the city on the map of European power. In 798, Pope Leo III elevated Salzburg to an archdiocese at the direct sponsorship of Emperor Charlemagne, making Arno the head of an ecclesiastical province that stretched from Bavaria deep into Pannonia and the Balkans. Salzburg became the staging ground for the Christianisation of Central Europe.
Arno was no mere administrator. A close friend of Charlemagne and correspondent of the English scholar Alcuin of York, he turned Salzburg into a beacon of Carolingian learning and scholarship. The intellectual culture he established at Stift St. Peter and around Salzburg Cathedral laid the groundwork for centuries of religious and cultural authority.
His archbishopric is the reason Salzburg became what it became. Without the metropolitan rank Arno secured, the city might have remained a provincial bishopric instead of a European capital.
