The Archbishops of Salzburg soon by this means gained a great and distinguished place amongst the German princes, which they retained until the power of the Emperors began to wane in consequence of differences with the Popes, to the latter of whom the Archbishops, as a rule, gave their support in the disputes that arose. Into these matters it is not necessary to enter deeply, but it was in consequence of them that Conrad I., Count of Abinberg, took the part of the Pope and caused the country to be greatly disturbed. During his reign the Abbey of St. Peter was granted as a residence to the Archbishop of Salzburg, and a new building was soon afterwards erected close by for the purpose. It was in the reign of this same Conrad I. that the Cathedral of Salzburg was destroyed by fire on May 4, 828, as was also a very large portion of the city. Both the Cathedral and the portion of the town which had been burnt down were rebuilt with even greater magnificence than before. But they were destined to once more be destroyed. Three centuries later, in the year 1167, a quarrel arose between Conrad II. and Frederick Barbarossa, because the latter refused to invest the former with the temporal power, and pronounced against him the ban of the Empire. Barbarossa ordered Salzburg and the country round about to be over-run and laid waste by the Counts Plain-Mittersill. For some time the city and its strong fortress resisted successfully; but on April 5, 1167, it was captured and once more burnt to the ground. The successor of Conrad, Albert III., a son of King Ladislav of Bohemia, also came into conflict with the Emperor, and shared a similar fate to his predecessors; but during the reigns of the immediately succeeding archbishops peace and prosperity were established, and under Eberhard II., who was distinguished as a most able and brilliant administrator as well as a great churchman, peace and tranquillity once more reigned. During the next century Salzburg was involved in political disputes and took part in the Battle of Muhldorf, on September 28, 1322, fighting on the side of Frederick the Schöne, Duke of Austria, who was taken prisoner. In consequence of which the principality not only lost large numbers of its chief nobles and knights, but also was involved in heavy monetary loss in the payment of its share of a war indemnity.
