Pseudo-Isidore is the conventional name for the unknown Carolingian-era author (or authors) behind an extensive corpus of influential forgeries. Pseudo-Isidore's main object was to provide accused bishops with an array of legal protections amounting to de facto immunity from trial and conviction; to secure episcopal autonomy within the diocese; and to defend the integrity of church property. The forgeries accomplished this goal, in part, by aiming to expand the legal jurisdiction of the Bishop of Rome.
