The peasants signified loudly, by rattle of arms, their approval of this sentiment; and the king, quite overawed, rose and said that he would yield and let the peasants have their way in this matter. The conditions of peace were thus accepted, and the time for the wedding was fixed. Björn and his men returned to Norway and received valuable gifts from King Olaf, for having successfully accomplished a difficult mission. Unhappily, however, the Swedish king, as soon as the danger was removed, began to reconsider his promise; and it gave him, no doubt, satisfaction to hear of his enemy's discomfort when, after vainly waiting for his bride on the boundary, he returned to Sarpsborg (1018). It did not occur to him that his own subjects, who had demanded the cessation of hostilities, might resent his undignified trick; and he was both surprised and alarmed when a revolt broke out, which came very near costing him his crown. Once more he had to make concessions, promise to make peace with the king of Norway, and accept his twelve-year-old son, Anund Jacob, as co-regent. King Olaf, of Norway, had, in the meanwhile, contrary to the will of her father, married Aastrid, a younger sister of Ingegerd. At the peace of Konghelle (1019), where the two kings finally met, this marriage was recognized by the king of Sweden, and friendly relations were established. The province of Jemteland remained in the possession of Olaf of Norway. This is the first time that Norway, as an integral kingdom, treats with a foreign power. The kings of Sweden and Denmark who claimed descent from Ragnar Lodbrok and through him from the gods, had never until now recognized the descendants of Harold the Fairhaired as rulers of a united realm and their own equals in dignity. Norway was to them merely a collection of small, scattered communities which, having once been united, made haste to fall to pieces again, and had at different times recognized the overlordship of the kings of Sweden and Denmark. The reluctance of the Swedish king to give his daughter in marriage to Olaf Haroldsson is therefore quite comprehensible.
