The archbishop in Nidaros was at that time Eystein, a son of Erlend Himalde, who descended from a very influential family in the Throndhjem district. In the summer of 1164 Erling Skakke had a conference with Archbishop Eystein in Bergen, where all the bishops of the country were then assembled, together with the legate from Rome, Stephanus. The result of the conference was that Magnus was to be anointed and crowned as king by the archbishop, while on the other hand it was agreed that in the future the church--represented by the archbishop and the other bishops, together with twelve leading men from each bishopric selected by the bishop--was to decide at the death of a king which one of his heirs was to succeed him; and if the king left no heirs of whom the magnates approved, they were to elect a successor to the throne. In the presence of the papal legate, the bishops, and a great many other clergymen, King Magnus, who was then eight years old, was anointed and crowned by the archbishop. Magnus, Erling's son, was the first crowned king in Norway. By this solemn act Erling Skakke believed he had secured his son's dynasty on the throne, and he could now with greater safety turn his whole attention to internal and foreign enemies, as he felt convinced that the greater part of the people would rally around the anointed king. When King Valdemar of Denmark heard that Erling Skakke had defeated Haakon Herdebred and Sigurd Markusfostre, and that his son Magnus had been crowned king of the whole country, he sent a message to Erling and reminded him of the agreement, by which Viken was to be ceded to the Danish king, if Magnus became king of Norway. Erling and his advisers showed no inclination to adhere to the agreement, and the messenger returned to Denmark without having accomplished anything. In the spring of 1165 King Valdemar sailed with a fleet north to Viken in order to take possession of the province. He tried peaceful proceedings; but he was so coolly received by the people of Viken that he returned to Denmark, preferring, as he said to his men, to use his army against the heathens of Vendland. The hostility between Norway and Denmark, however, lasted some time. Erling made a cruise to Jutland and defeated the Danes in a battle at Dyrsaa, and returned to Norway with a great booty. A second expedition of King Valdemar to Viken in the spring of 1168 became as indecisive as the first, so far as establishing any authority there; but he dealt the inhabitants of Viken a hurtful blow by forbidding them to trade with Denmark, at the same time forbidding the Danes to export grain to Norway.
