Quite in keeping with the general reactionary character of the earls' government, was the revival of the viking cruises which, during the reign of Olaf Tryggvesson, had been diminishing in frequency. Earl Erik himself had been a valiant viking in his youth, and probably could see no harm in the careless and predatory life in which the old Germanic paganism found its most characteristic expression. A great impetus must have been given to this mode of life by Sweyn Forkbeard's repeated expeditions to England, in which a large number of Norsemen participated. It makes little difference if the aggressors were nominally Christians; their actions were an outburst of the old, tribal pagan spirit, which respected no right but that of might. It was natural that the earls, if they expected to make their dominion permanent, should endeavor to extend their connections beyond Tröndelag. The strength of a government in those days depended largely upon the support which it received among the chieftains or tribal aristocracy, whose sentiments were usually reflected by the peasants. It was therefore necessary in some way to conciliate the late adherents of Olaf Tryggvesson, whose influence upon public opinion could be utilized to advantage. It may have been some such consideration which restrained Earl Erik from attacking Erling Skjalgsson. It is obvious that the overtures which he made to Einar Thambarskelver had the same end in view. We have seen how the young archer came within an inch of ending the earl's days at Svolder, thereby exciting the admiration of Erik for his skill and bravery. After the battle, the earl, with his usual generosity, spared his life, and sought in many ways to secure his friendship. He married him to his sister, the high-minded Bergljot, and gave him large fiefs, so that no chieftain in Tröndelag could rival him in power.
