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.

The term Extravagantes (from the Latin extra, outside; vagari, to wander) is applied to the canon law of the Roman Catholic Church, to designate some papal decretals not contained in certain canonical collections which possess a special authority. More precisely, they are not found in Gratian's Decretum or the three official collections of the Corpus Juris Canonici (the Decretals of Gregory IX, the Sixth Book of the Decretals, and the Clementines).
