In the name of omnipotent God, the Father, Son, and Holy Ghost. We, Otto, by the grace of God emperor and Augustus, together with our glorious son, king Otto, promise and pledge to thee, St. Peter, prince of apostles and keeper of the keys of heaven, and through thee to thy vicar, pope John XII, the following possessions, as his predecessors have held and possessed them up to the present time; namely, (1) the city of Rome with its duchy, and its neighboring villages and territories, highland and lowland, shores and ports; (2) all the cities, towns, fortresses, and villages of Tuscany; that is, Porto, Civita Vecchia, Ceri, Bieda, Marturianum, Sutri, Nepi, Gallese, Orte, Polimartium, Ameria, Todi, Perugia, with its three islands, the larger and the smaller, and Pulvensis, Narni, and Otricoli, with all the territories belonging to the aforesaid cities; (3) the whole exarchate of Ravenna with all the cities, towns, and fortresses which our predecessors the most excellent emperors, Pippin and Karl, conferred on St. Peter and your predecessors by a deed of gift; namely, the city of Ravenna and the district of Emilia, including the following towns: Bobbio, Cesena, Forlimpopoli, Forli, Faenza, Imola, Bologna, Ferrara, Comacle, Adria, and Gabello, with all the territories and islands by land and sea which belong to the aforesaid cities; (4) likewise also the Pentapolis; that is, Rimini, Pesaro, Fano, Sinigaglia, Ancona, Osimo, Humana, Iesi, Forum Sempronii, Montefeltre, Urbino, and the territory of Balneum, Cagli, Lucioli, and Gubbio, with all the territories belonging to the aforesaid cities; (5) likewise the whole Sabine territory as it was granted to St. Peter by our predecessor, emperor Karl, by a deed of gift; (6) likewise in Lombard Tuscany the fortress of Felicitas, and the towns of Orvieto, Bagnorea, Ferento, Viterbo, Orcle, Marca, Toscanella, Soana, Populonia, and Roselle, with all their suburbs and villages and all their territories, towns, and boundaries; (7) and likewise from Luna, with the island of Corsica, to Suriano, thence over the Apennines to Berceto, thence to Parma, thence to Reggio, thence to Mantua and Monselice, together with the provinces of Venetia and Istria and all the duchies of Spoleto and Benevento, and the church of St. Christina which is situated on the Po about four miles from Pavia; (8) and likewise in Campania, Sora, Arce, Aquino, Arpino, Teano, Capua; (9) likewise the patrimonies under your power and sway, such as the patrimonies of Benevento, Naples, and upper and lower Calabria, and also of the island of Sicily, if God shall give it unto our hand; (10) likewise the cities of Gaeta and Fondi with all their belongings; (11) moreover we offer to thee, St. Peter, the apostle, and to thy vicar, pope John and his successors, for the salvation of our own soul and the souls of our son and our parents, the following cities and towns from our own lands; namely, Rieti, San Vittorino [on the Aterno], Furco, Norcia, Balua, Marsi, and besides the city of Teramne. (12) All the aforesaid provinces, cities, towns, fortresses, villages, territories, and patrimonies, we now grant to thee, St. Peter, and through thee to thy vicar, our spiritual father, pope John, and his successors to the end of the world, for the salvation of our own soul and the souls of our son, our parents, and our successors, and for the preservation of the whole Frankish people; and we grant them in such a way that the popes shall possess them in their own right and government and control. (13) Likewise, by this agreement we confirm all the gifts which king Pippin and emperor Karl voluntarily gave to St. Peter, the apostle, and also the rents and payments and taxes which were paid annually to the king of the Lombards from Tuscany and the duchy of Spoleto, as is contained in the aforesaid donation and as was agreed upon between pope Adrian of blessed memory and the emperor Karl, when the same pope surrendered to the emperor his claims on the provinces of Tuscany and Spoleto on condition that the aforesaid taxes should be paid each year to the church of St. Peter, the apostle. But in all this our authority over these provinces and their subjection to us and to our son are not in any way diminished. (14) We therefore confirm your possession of all the things mentioned above in this document; they shall remain in your right and ownership and control, and no one of our successors shall on any pretext take from you any part of the aforesaid provinces, cities, towns, fortresses, villages, dependencies, territories, patrimonies, or taxes, or lessen your authority over them. We will never do so, nor allow others to do so, but we will always defend the church of St. Peter and the popes who rule over that church in their possession of all these things, as far as in us lies, that the popes may be able to keep these things in their control to use, enjoy, and dispose of. (15) In all this there shall be no derogation of our power or of the power of our son and our successors.

55. Leo VIII Grants the Emperor the Right to Choose the Pope and Invest all Bishops, 963.

Cor. Jur. Can., Dist. LXIII, c. xxiii; Migne, 134, cols. 992 ff.

Otto I, after the rebellion of John XII, deposed him and caused a layman to be made pope, who took the title Leo VIII. The new pope then issued a decree, the essence of which is contained in the following document. It shows how determined Otto was to assert his imperial authority and is important as a statement of the imperial theory. Leo VIII is regarded as an anti-pope by the Roman church, because, according to the papal theory, Otto had no power to depose a pope. John XII was the legal pope and there could be no other until he died.

In the synod held at Rome in the Church of the Holy Saviour. Following the example of blessed pope Adrian, who granted to Karl, victorious king of the Franks and Lombards, the dignity of the patriciate and the right to ordain the pope and to invest bishops, we, Leo, bishop, servant of the servants of God, with all the clergy and people of Rome, by our apostolic authority bestow upon lord Otto I, king of the Germans, and upon his successors in the kingdom of Italy forever, the right of choosing the successor of the pope, and of ordaining the pope and the archbishops and bishops, so that they shall receive their investiture and consecration from him, with the exception of those prelates whose investiture and consecration the emperor has conceded to the pope or the archbishops. No one, no matter what his dignity or ecclesiastical rank, shall have the authority to choose the patricius or to ordain the pope or any bishop without the consent of the emperor, and that without bribery; and the emperor shall be by right both king [of Italy] and patricius [of Rome]. But if anyone has been chosen bishop by the clergy and people, he shall not be consecrated unless he has been approved by the aforesaid king and has received his investiture from him....

56. The Pope Confers the Royal Title. A Letter of Pope Sylvester II to Stephen of Hungary, 1000.

Migne, 139, cols. 274 ff.

Previous to this time, it was considered the emperor’s right to confer the royal title and to elevate a person to the rank of king. Here, for the first time in the history of the papacy, a pope confers the royal title, thereby intrenching on the imperial prerogative. Otto III, who was then emperor, did not resist this papal infringement of his rights. Later popes were not slow to see the value of this act as a precedent (see nos. [69], [72], [128]), and exercised the right to confer titles and dignities as they pleased. This act of Sylvester II is, therefore, an important milestone in the history of the development of the papal prerogatives.

Sylvester, bishop, servant of the servants of God, to Stephen, king of the Hungarians, greeting and apostolic benediction. Your ambassadors, especially our dear brother, Astricus, bishop of Colocza, were received by us with the greater joy and accomplished their mission with the greater ease, because we had been divinely forewarned to expect an embassy from a nation still unknown to us.... Surely, according to the apostle: "It is not of him that willeth nor of him that runneth, but of God that showeth mercy" [Rom. 9:16]; and according to the testimony of Daniel: "He changeth the times and the seasons; he removeth kings and setteth up kings; he revealeth the deep and secret things; he knoweth what is in the darkness" [Dan. 2:21, 22]; for in him is that light which, as John teaches, "lighteth every man that cometh into the world" [John 1:9]. Therefore we first give thanks to God the Father, and to our Lord Jesus Christ, because he has found in our time another David, and has again raised up a man after his own heart to feed his people Israel, that is, the chosen race of the Hungarians. Secondly, we praise you for your piety toward God and for your reverence for this apostolic see, over which, not by our own merits, but by the mercy of God, we now preside. Finally, we commend the liberality you have shown in offering to St. Peter yourself and your people and your kingdom and possessions by the same ambassadors and letters. For by this deed you have clearly demonstrated that you already are what you have asked us to declare you [i.e., a king]. But enough of this; it is not necessary to commend him whom God himself has commended and whose deeds openly proclaim to be worthy of all commendation. Now therefore, glorious son, by the authority of omnipotent God and of St. Peter, the prince of apostles, we freely grant, concede, and bestow with our apostolic benediction all that you have sought from us and from the apostolic see; namely, the royal crown and name, the creation of the metropolitanate of Gran, and of the other bishoprics. Moreover, we receive under the protection of the holy church the kingdom which you have surrendered to St. Peter, together with yourself and your people, the Hungarian nation; and we now give it back to you and to your heirs and successors to be held, possessed, ruled, and governed. And your heirs and successors, who shall have been legally elected by the nobles, shall duly offer obedience and reverence to us and to our successors in their own persons or by ambassadors, and shall confess themselves the subjects of the Roman church, who does not hold her subjects as slaves, but receives them all as children. They shall persevere in the catholic faith and the religion of our Lord and Saviour Jesus Christ, and strive always to promote it. And because you have fulfilled the office of the apostles in preaching Christ and propagating his faith, and have tried to do in your realm the work of us and of our clergy, and because you have honored the same prince of apostles above all others, therefore by this privilege we grant you and your successors, who shall have been legally elected and approved by the apostolic see, the right to have the cross borne before you as a sign of apostleship,[{68}] after you have been crowned with the crown which we send and according to the ceremony which we have committed to your ambassadors. And we likewise give you full power by our apostolic authority to control and manage all the churches of your realm, both present and future, as divine grace may guide you, as representing us and our successors. All these things are contained more fully and explicitly in that general letter which we have sent by our messenger to you and to your nobles and faithful subjects. And we pray that omnipotent God, who called you even from your mother’s womb to the kingdom and crown, and who has commanded us to give you the crown which we had prepared for the duke of Poland, may increase continually the fruits of your good works, and sprinkle with the dew of his benediction this young plant of your kingdom, and preserve you and your realm and protect you from all enemies, visible and invisible, and, after the trials of the earthly kingship are past, crown you with an eternal crown in the kingdom of heaven. Given at Rome, March 27, in the thirteenth indiction [the year 1000].

{68} The title "apostolic king of Hungary" is still used by the emperor of the Austro-Hungarian Empire.
