Pope Hormisdas (; c. 450 – 6 August 523) was the bishop of Rome from 20 July 514 to his death. His papacy was dominated by the Acacian schism, started in 484 by Acacius of Constantinople's efforts to placate the Monophysites. His efforts to resolve this schism were successful, and on 28 March 519, the reunion between Constantinople and Rome was ratified in the cathedral of Constantinople before a large crowd.

Family and early career
Hormisdas was born in Frusino in the moribund era of the Western Roman Empire. His Persian name was probably given in honour of an exiled Persian noble, Hormizd, "celebrated in the Roman martyrology (8 August) but not so honoured in the East." The names of his father and son suggest he had an otherwise "straightforward Italian pedigree." However, according to Iranica he was probably related to Hormizd.<ref>Hormozod, A. Shapur Shahbazi, 'Encyclopaedia Iranica (March 23, 2012).</ref>

Before becoming a deacon, Hormisdas was married and had a son, Silverius, who later became pope. During the Laurentian schism, Hormisdas was one of the most prominent clerical partisans of Pope Symmachus. He was notary at the synod held at St. Peter's in 502. Two letters of Magnus Felix Ennodius, bishop of Pavia, survive addressed to him, written when the latter tried to regain horses and money he had lent the Pope.

Pontificate
Unlike that of his predecessor Symmachus, the election of Hormisdas lacked any notable controversies. Upon becoming pope, one of Hormisdas' first actions was to remove the last vestiges of the schism in Rome, receiving back into the Church those adherents of the Laurentian party who had not already been reconciled. "The schism had lingered on largely out of personal hatred to Symmachus," writes Jeffrey Richards, "something with which Hormisdas was apparently not tainted."

The account of his tenure in the Liber Pontificalis, as well as the overwhelming bulk of his surviving correspondence, is dominated by efforts to restore communion between the Sees of Rome and Constantinople caused by the Acacian schism. This schism was the consequence of the "Henoticon" of the Emperor Zeno and supported by his successor Anastasius, who became more and more inclined towards Monophysitism and persecuted those bishops who refused to repudiate the Council of Chalcedon.

The emperor Anastasius took the first steps to resolve this schism pressured by Vitalian, the commander of the imperial cavalry, who, having taken up the cause of orthodoxy, led Thracia, Scythia Minor, and Mysia to revolt, and marched with an army of Huns and Bulgarians to the gates of Constantinople. Richards points out that there would bound to be some tentative efforts from Constantinople, "if only because there was a new man on the throne of St. Peter. Relations between Symmachus and the emperor Anastasius had been virtually non-existent".

Anastasius wrote to Hormisdas on 28 December 514, inviting him to a synod that would be held 1 July of the following year. A second, less courteous invitation, dated 12 January 515, was also sent by Anastasius to the pope, which reached Rome before the first. On 4 April Hormisdas answered, expressing his delight at the prospect of peace, but at the same time defending the position of his predecessors and welcoming a synod, but believing it unnecessary. The bearers of the emperor's first letter at last reached Rome on 14 May. The pope guardedly carried on negotiations, convened a synod at Rome and wrote to the emperor on 8 July to announce the departure of an embassy for Constantinople. Meanwhile, the two hundred bishops who had assembled on 1 July at Heraclea separated without accomplishing anything.

The pope's embassy to the imperial court consisted of two bishops, Ennodius of Pavia and Fortunatus of Catina, the priest Venantius, the deacon Vitalis, and the notary Hilarius. According to Rev. J. Barmby, Hormisdas made several demands: (1) The emperor should publicly announce his acceptance of the Council of Chalcedon and the letters of Pope Leo; (2) the Eastern bishops should make a similar public declaration, and in addition anathematize Nestorius, Eutyches, Dioscorus, Aelurus, Peter Mongus, Peter the Fuller, and Acacius, with all their followers; (3) everyone exiled in this dispute should be recalled and their cases reserved for the judgment of the Apostolic See; (4) those exiles who had been in communion with Rome and professed Catholicism should first be recalled; and (5) bishops accused of having persecuted the Orthodox should be sent to Rome to be judged. "Thus the emperor proposed a free discussion in council; the pope required the unqualified acceptance of orthodoxy, and submission to himself as head of Christendom, before he would treat at all."

An imperial embassy of two high civil officials came to Rome bringing one letter dated 16 July 516 for the pope, and one dated 28 July for the Roman Senate; the aim of the latter was to convince the senators to take a stand against Hormisdas. However both the Senate, as well as King Theodoric, stayed loyal to the pope. Meanwhile, Hormisdas reported to Avitus of Vienne that an additional number of Balkan bishops had entered into relations with Rome, and Bishop John of Nicopolis, who was also the archbishop of Epirus, had broken communion with Constantinople and resumed it with Rome.

A second papal embassy consisting of Ennodius and Bishop Peregrinus of Misenum was as unsuccessful as the first. Anastasius even attempted to bribe the legates, but was unsuccessful. Secure now that Vitalian had been defeated outside Constantinople, forced into hiding, and his supporters executed, Anastasius announced on 11 July 517 that he was breaking off the negotiations. But less than a year later the emperor died; the Liber Pontificalis'' claims he was struck dead by a thunderbolt. His successor, the Catholic Justin I, immediately reversed Anastasius' policies. All the demands of Pope Hormisdas were granted: the name of the condemned Patriarch Acacius as well as the names of the Emperors Anastasius and Zeno were stricken from the church diptychs, and the Patriarch John II accepted the formula of Hormisdas. Some maintain that he did so with some qualifications. This argument is based on the following quote:"I declare that the see of apostle Peter and the see of this imperial city are one."

However, the East continued to disregard papal demands by not condemning Acacius. On 28 March 519, in the cathedral of Constantinople in the presence of a great throng of people, the end of the schism was concluded in a solemn ceremony.
