ABSTRACT
The missions to Sweden and Denmark were divided sometime in the early 830s. The Vita Anskarii only returns to the history of the northern mission as disaster befalls it. The loss of Turholt around 845 following the division of the empire, and the sack of Hamburg in 845, both receive prominent mention. After the destruction of Hamburg, Rimbert laments that "Our lord bishop was beset by numerous calamities and anxieties, and the brothers of his congregation, wandered here and there from place to place and had no refuge. Louis's privilege is addressed to "the sons, present and future, of the holy church of God". The arenga explains the emperor's obligation to govern and guard the Christian church, which Christ has committed to his care. The authentic immunity buried in Louis's privilege provides the best means of identifying the inauthentic material. Immunities issued by Louis's chancery were strictly formulaic documents and all adhere broadly to the same set of norms.
