Papal appointment

Papal appointment was a medieval method of selecting the Pope. Popes have always been selected by a council of Church fathers; however, Papal selection before 1059 was often characterized by confirmation or nomination by secular European rulers or by the preceding pope. The later procedures of the Papal conclave are in large part designed to prohibit interference of secular rulers, which to some extent characterized the first millennium of the Roman Catholic Church, e. g. in practices such as the creation of crown-cardinals and the claimed but invalid jus exclusivae. Appointment may have taken several forms, with a variety of roles for the laity and civic leaders, Byzantine and Germanic emperors, and noble Roman families. The role of the election vis-a-vis the general population and the clergy was prone to vary considerably, with a nomination carrying weight that ranged from nearly determinative to merely suggestive, or as ratification of a concluded election.
The practice originated in late antiquity, where on many occasions the Roman Emperor stepped in to resolve disputes over the legitimacy of Papal contenders. An important precedent from this period is an edict of Emperor Honorius, issued after a synod he convoked to depose Antipope Eulalius. The practice passed to, and grew with, the King of the Ostrogoths, and then the Byzantine Emperor. After an interregnum, the Kings of the Franks and the Holy Roman Emperor, generally assumed the role of confirming Papal elections. For a period, today known as the "saeculum obscurum", the practice passed from the Emperor to powerful Roman nobles—the Crescentii and then the Counts of Tusculum.
In many cases, the Papal coronation was delayed until the election had been confirmed. Some antipopes were similarly, putatively, appointed. The practice ended with the conclusion of the Investiture Controversy due largely to the efforts of Cardinal Hildebrand, the future Pope Gregory VII, who was a guiding force in the selection of his four predecessors, and the 1059 Papal bull In Nomine Domini of Pope Nicholas II; some writers consider this practice to be an extreme form of "investiture" in and of itself.
Although the practice was forbidden by the Council of Antioch and the Council of Rome, the Bishops of Rome, as with other bishops, often exercised great control over selection of their successors, even after the sixth century. In addition, most popes of the fourth to twelfth centuries were nominated or confirmed by a secular power.

Ancient Rome

As to the earliest ages, St. Peter himself constituted a senate for the Roman Church, consisting of twenty-four priests and deacons. These were the councillors of the Bishop of Rome and the electors of his successors. This statement is drawn from a canon in the "Corpus Juris Canonici". Historians and canonists, however, generally hold that the Roman bishopric was filled on its vacancy in the same manner as other bishoprics, that is, the election of the new pope was made by the neighbouring bishops and the clergy and faithful of Rome. Nevertheless, some maintain that the naming of the successor of St. Peter was restricted to the Roman clergy, and that the people were admitted to a part in the elections only after the time of Sylvester I.
After Constantine had given peace to the Church, the Christian Roman emperors often took part in the institution of a new pope and at times their influence was very marked. From the fourth century onwards, therefore, a new force had to be reckoned with. The occasion for the interference of the Roman emperors and later of the kings of Italy was afforded by disputed elections to the papal chair. The most noted of the earlier instance was at the election of Boniface I. This gave occasion to the decree that when an election was disputed a new candidate should be chosen.

Ostrogoths

On November 22, 498, both Pope Symmachus and Antipope Laurentius were elected pope; both Byzantine Emperor Anastasius I and the Gothic King Theodoric the Great originally supported Laurentius, who was installed in the Lateran Palace, but Symmachus prevailed when Theodoric expelled Laurentius from Rome, fearing that he was too influenced by the Byzantine ruler.

Justinian I	Pelagius I	April 16, 556 – March 4, 561	"Pelagius, as the nominee of Justinian, at once succeeded on his arrival in Rome, but most of the clergy, suspecting his orthodoxy, and believing him to have had some share in the unlooked-for removal of his predecessor, shunned his fellowship, and only two bishops and presbyter could be got to take part in his ordination to the pontificate"
Justinian I	John III	July 17, 561 – July 13, 574	"At the death of Pelagius I, Rome had been under Byzantine control for many years, and according to the procedure imposed by Constantinople, the name of the elected candidate had to be submitted to the emperor for approval.

Justin II	Benedict I	June 2, 575 – June 30, 579	"The ravages of the Lombards rendered it very difficult to communicate with the emperor at Constantinople, who claimed the privilege of confirming the election of the popes.

Tiberius II Constantine	Pelagius II	November 26, 579 – February 7, 590	"He succeeded Benedict I, when the Lombards were besieging Rome, but his consecration was delayed in the hope of securing the confirmation of the election by the emperor.

Maurice	Gregory I	September 3, 590 – March 12, 604	"The choice of a successor lay with the clergy and people of Rome, and without any hesitation they elected Gregory wrote personally to the Emperor Maurice, begging him with all earnestness not to confirm the election. Germanus, prefect of the city, suppresses this letter, however, and sent instead of it the formal schedule of the election. In the interval while awaiting the emperor's reply the business of the vacant see was transacted by Gregory At length, after six months of waiting, came the emperor's confirmation of Gregory's election."

Heraclius	Severinus	October 638 – August 2, 640	"Severinus was elected and envoys were at once sent to Constantinople, to obtain the confirmation of his election.

Crescentii

Crescentius the Elder, the brother of Pope John XIII, had previously deposed and had strangled Pope Benedict VI, and helped install Antipope Boniface VII in Rome in opposition to the imperial candidates, Pope Benedict VII and Pope John XIV, the latter of which perished in the Castel Sant'Angelo like Benedict V. Crescentius the Younger, the son of Crescentius the Elder, likely had a strong hand in the election of Pope John XV, although the details of that papacy are incomplete and disputed. However, it is known that Crescentius the Younger deferred to Otto III, Holy Roman Emperor for the choice of the successor of John XV: Pope Gregory V, Otto III's cousin. Yet, not long afterward, disputes with the emperor and Gregory V caused Crescentius the Younger to support Antipope John XVI, who was deposed with some difficulty by Otto III, who proceeded to have John XVI mutilated and Crescentius the Younger killed.
Three years later, after a revolt in Rome involving John Crescentius, the son of Crescentius the Younger, Otto III and Pope Sylvester II were expelled from Rome; the three successors of Sylvester II were appointed by John Crescentius before he died in the spring of 1012, nearly simultaneously with Sergius IV, allowing the Counts of Tusculum to displace the Crescentii.

Counts of Tusculum

Unlike the Tusculan popes during the "Pornocracy", Benedict VIII, John XIX, and Benedict IX were the Count of Tusculum themselves immediately prior to their becoming pope. Benedict VIII subjugated the Crescentii and made peace with the Holy Roman Empire, crowning Henry II, Holy Roman Emperor on February 14, 1014, nearly two years after his accession to the papacy.

Henry III	Victor II	April 13, 1055 – July 28, 1057	"After the death of Leo IX Cardinal-subdeacon Hildebrand came to the emperor at the head of a Roman legation with the urgent request to designate Gebhard as pope. At the Diet of Mainz, in September, 1054, the emperor granted this request, but Gebhard refused to accept the papal dignity. At a court Diet held at Ratisbon in March, 1055, he finally accepted the papacy, but only on condition that the emperor restored to the Apostolic See all the possessions that had been taken from it. The emperor consented to this condition and Gebhard accompanied Hildebrand to Rome, where he was formally elected and solemnly enthroned on Maundy Thursday, 13 April 1055, taking the name of Victor II."

His elevation, due to violence and corruption, was contrary to the specific orders of Stephen X that, at his death, no choice of a successor was to be made until Hildebrand's return from Germany. Several cardinals protested against the irregular proceedings, but they were compelled to flee from Rome. Hildebrand was returning from his mission when the news of these events reached him. He interrupted his journey at Florence, and after agreeing with Duke Godfrey of Lorraine-Tuscany upon Bishop Gerhard for elevation to the papacy, he won over part of the Roman population to the support of his candidate. An embassy dispatched to the imperial court secured the confirmation of the choice by the Empress Agnes. At Hildebrand's invitation, the cardinals met in December, 1058, at Siena and elected Gerhard who assumed the name of Nicholas II. On his way to Rome the new pope held at Sutri a well-attended synod at which, in the presence of Duke Godfrey and the imperial chancellor, Guibert of Parma, he pronounced deposition against Benedict X."
