However, according to the laws that were put to paper during the following 200 years, the King of Sweden was obliged to take hostages from the powerful clans when he entered a former petty kingdom to be accepted as their king as well. Moreover, the regnal list of the West Geats (Westrogoths) claims that his not taking hostages showed his arrogance. This is also the traditional Swedish interpretation why he was killed.
