The description of the oath taking ceremony mirrors the political and societal changes during Anonymus' lifetime. The increasing power of the nobles and their need for the codification of their rights culminated in the issuing of the Golden Bull of 1222. Several historians concluded that Anonymus' intentions in writing down this agreement were to express the societal changes during his own period, and support the fight for the rights of the nobility, as a kind of historical justification. According to historian István Nemeskürty "The aim of Magister P. (Anonymus) is to justify the rights and claims of 13th century Hungarian nobility and create a lineage going back to the Conquest for all of his friends and family. Also, although Anonymus stresses that his works are based on written sources, he wanted to create a literary work in the style of his own time period."
