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.Fanning, William. "Papal Elections." The Catholic Encyclopedia Vol. 11. New York: Robert Appleton Company, 1911. 6 October 2017 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 (or his delegate, the Exarch of Ravenna). After an interregnum, the Kings of the Franks and the Holy Roman Emperor (whose selection the Pope also sometimes influenced), 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 (cf. confirmation of bishops) 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.Brauer, Jerald C., and Gerrish, Brian Albert. 1971. The Westminster Dictionary of Church History. Westminster Press. . p. 216.

Although the practice was forbidden by the Council of Antioch (341) and the Council of Rome (465), the Bishops of Rome, as with other bishops, often exercised great control over selection of their successors, even after the sixth century.Josep M. Colomer and Iain McLean. (1998). "Electing Popes: Approval Balloting and Qualified-Majority Rule". The Journal of Interdisciplinary History, Vol. 29, No. 1, pp. 1-22. 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" (can. "Si Petrus", caus. 8, Q. 1). 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 (fourth century).

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 (418). This gave occasion to the decree (c. 8, dist. 79) 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.DeCormenin and de Lahaye, 1857, p. 98.
