In 834 Hamburg became an archbishopric, St Ansgar, a monk of Corbie and known as the apostle of the North, being the first metropolitan.
He became a monk of Corbie, near Amiens in Picardy, in 814, and assumed, the cloister name of Paschasius.
It was Anschar, a monk of Corbie, who first preached to the Scandinavians, and other Benedictines were apostles to Poles, Prussians and other Slavonic peoples..
He had by this time aroused against him the full fury of the Jesuits, and at their instigation a royal provost was sent to Corbie to arrest him.
Soon after his accession the territory that had been bestowed on the popes by Pippin was invaded by Desiderius, king of the Lombards, and Adrian found it necessary to invoke the aid of Charlemagne, who entered Italy with a large army, besieged Desiderius in his capital of Pavia, took that town, banished the Lombard king to Corbie in France and united the Lombard kingdom with the other Frankish possessions.
