About the year 860,
After his return to Constantinople, Cyril assumed the role of professor of philosophy at the university. His brother had by this time become a significant figure in Byzantine political and administrative affairs, and an abbot of his monastery.
Mission to the Slavs
Great Moravia

In 862, the brothers began the work which would give them their historical importance. That year Prince
For the purpose of this mission, they devised the

Exactly how much the brothers translated is impossible to say for certain. The New Testament and the Psalms seem to have been the first, followed by other lessons from the Old Testament.[citation needed] The "Translatio" speaks only of a version of the Gospels by Cyril, and the "Vita Methodii" only of the "evangelium Slovenicum", though other liturgical selections may also have been translated.
Nor is it known for sure which liturgy, whether of Rome or of Constantinople, they took as a source. They may well have used the

The mission of Constantine and Methodius had great success among Slavs in part because they used the people's native language rather than Latin or Greek. In Great Moravia, Constantine and Methodius also encountered missionaries from East Francia. They would have represented the western, or Latin, branch of the Church, more particularly epitomizing the Carolingian Empire as founded by Charlemagne, and intent on linguistic and cultural uniformity. They insisted on the use of the Latin liturgy, and they regarded Moravia and the Slavic peoples as part of their rightful mission field.
When friction developed, the brothers, unwilling to be a cause of dissension among Christians, decided to travel to Rome to see the Pope, and seek a solution that would avoid quarrelling between missionaries in the field. In 867,
With them they brought the relics of
The brothers sought support from Rome, and arrived there in 868, where they were warmly received. This was partly due to their bringing with them the relics of Saint Clement; rivalry with Constantinople over the territory of the Slavs would have inclined Rome to value the brothers and their influence.[20]
The brothers were praised for their learning and cultivated for their influence in Constantinople. Anastasius Bibliothecarius would later call Cyril "a man of apostolic life" and "a man of great wisdom".[24] Their project in Moravia found support from the new Pope Adrian II (867-872), who formally authorized the use of the new Slavic liturgy.
Subsequently, Methodius was ordained as priest by the pope himself, and five Slavic disciples were ordained as priests (
The newly made priests officiated in their own language at the altars of some of the principal churches.Feeling his end approaching, Cyril became a Basilian monk and was given the name Cyril.[28] He died in Rome fifty days later (14 February 869). There is some question whether he had been made a bishop, as is asserted in the Translatio (ix.). Upon Cyril´s death Methodius was given the title of Archbishop of Sirmium (now Sremska Mitrovica in Serbia) with jurisdiction over all of Moravia and Pannonia, and authority to use the Slavonic Liturgy.[29] The statement of the "Vita" that Methodius was made bishop in 870 and not raised to the dignity of an archbishop until 873 is contradicted by the brief of Pope John VIII, written in June 879, according to which Adrian consecrated him archbishop; John includes in his jurisdiction not only Great Moravia and Pannonia, but Serbia as well.
Methodius alone

Methodius now continued the work among the Slavs alone; not at first in Great Moravia, but in Pannonia (in the
Notwithstanding strong representations of the
Methodius' final years
The papal will prevailed, and Methodius secured his freedom and his archiepiscopal authority over both Great Moravia and Pannonia, albeit without the use of Slavonic for
In 878, Methodius was summoned to Rome on charges of heresy and using Slavonic. This time Pope John was convinced by the arguments that Methodius made in his defence and sent him back cleared of all charges, and with permission to use Slavonic. The Carolingian bishop who succeeded him, Wiching, a Swabian, suppressed the Slavonic Liturgy and forced the followers of Methodius into exile. Many found refuge with Knyaz Boris the Baptizer in Bulgaria, under whom they reorganized a Slavic-speaking Church. Meanwhile, Pope John's successors adopted a Latin-only policy which lasted for centuries.
Methodius vindicated his orthodoxy and promised to obey with regard to the liturgy. He could the more easily defend his omission of Filioque from the creed as this also pertained in Rome at the time. Though Filioque could, by the 6th century, be heard in some Latin-speaking churches in the west, it was not to be until 1014 that Rome followed suit (see Nicene Creed). Methodius' critics were mollified by Methodius having to accept the appointment of Wiching as his coadjutor. When relations between the two factions again became strained, John VIII steadfastly supported Methodius. After his death (December 882) it was the archbishop himself whose position looked insecure. His need for political support, visiting the Eastern emperor, inclined Goetz to accept the account in the Vita (xiii.).
Methodius died on 6 April 885[32] and his body was buried in the main cathedral church of Great Moravia. It still remains an open question which city was capital of Great Moravia. As a result the location of Methodius' body remains uncertain.[33]
Upon Methodius' death an animosity erupted into open conflict. Amongst the disciples of Cyril and Methodius, Clement of Ohrid headed the struggle against the German clergy in Great Moravia along with Gorazd upon the death of Methodius in 885. Gorazd, whom Methodius had designated as his successor, was not recognised by Pope Stephen V. This pope now also forbade the Slavic liturgy[34] and placed as Methodius' successor the infamous Wiching who promptly sent disciples of Cyril and Methodius into exile from Great Moravia.
After spending some time in jail, Clement was expelled from Great Moravia, and in 885 or 886 reached the borders of the
Invention of the Glagolitic and Cyrillic alphabets


The Glagolitic and Cyrillic alphabets are the oldest known Slavic
The early Glagolitic alphabet was used in Great Moravia between 863 (the arrival of Cyril and Methodius) and 885 (the expulsion of their students) for government and religious documents and books, and at the Great Moravian Academy (Veľkomoravské učilište) founded by Cyril, where followers of Cyril and Methodius were educated, by Methodius himself among others. The alphabet has been traditionally attributed to Cyril. That seems confirmed explicitly by the papal letter Industriae tuae (880) approving the use of Old Church Slavonic, which says that the alphabet was "invented by Constantine the Philosopher". "Invention" need not exclude the brothers having possibly made use of earlier letterforms. Before that time the Slavic languages had no distinct script of their own.
The
After the adoption of Christianity in 865, religious ceremonies in Bulgaria were conducted in Greek by clergy sent from the Byzantine Empire. Fearing growing Byzantine influence and weakening of the state, Boris viewed the adoption of the Old Slavonic language as a way to preserve the political independence and stability of Bulgaria, so he established two literary schools (academies), in

The day is now celebrated as a public holiday in the following countries:
- In Bulgaria it is celebrated on 24 May and is known as the "Bulgarian Education and Culture, and Slavonic Script Day" (Bulgarian: Ден на българската просвета и култура и на славянската писменост), a national holiday celebrating Bulgarian culture and literature as well as the alphabet. It is also known as "Alphabet, Culture, and Education Day" (Bulgarian: Ден на азбуката, културата и просвещението). Saints Cyril and Methodius are patrons of the National Library of Bulgaria. There is a monument to them in front of the library. Saints Cyril and Methodius are the most celebrated saints in the Bulgarian Orthodox church, and icons of the two brothers can be found in every church.
- In North Macedonia, it is celebrated on 24 May and is known as the "Saints Cyril and Methodius, Slavonic Enlighteners' Day" (Macedonian: Св. Кирил и Методиј, Ден на словенските просветители), a national holiday. The Government of the Republic of Macedonia enacted a statute of the national holiday in October 2006 and the Parliament of the Republic of Macedonia passed a corresponding law at the beginning of 2007.[41] Previously it had only been celebrated in the schools. It is also known as the day of the "Solun Brothers" (Macedonian: Солунските браќа).
- In the
- In Russia, it is celebrated on 24 May and is known as the "Slavonic Literature and Culture Day" (Russian: День славянской письменности и культуры), celebrating Slavonic culture and literature as well as the alphabet. Its celebration is ecclesiastical (11 May in the Church's Julian calendar). It is not a public holiday in Russia.

The most important instance where translation and the beginning church did coincide closely was in Slavonic under the brothers Cyril and Methodius, with the Bible completed by A.D. 880.
