Gottschalk of Aachen (fl. 1071–1104) was a German monk, notary, poet and composer. A supporter of King Henry IV during the Investiture Contest, his writings laid the theoretical foundation for the state's anti-papal propaganda.[1]
^McGrade 2010: "His vision of the relationship between the pope and the German emperor became the conceptual basis of imperial propaganda". Robinson 1999, p. 11: he "was the first royal supporter to formulate a theoretical defence of Henry IV's kingship. The arguments presented in his polemics of 1076 continued to influence 'state propaganda' for the rest of the century."
