John VI Kantakouzenos

John VI Kantakouzenos or Cantacuzenus (Greek: Ἰωάννης ΣΤʹ Καντακουζηνός, Iōannēs ST′ Kantakouzēnos; c. 1292 – 15 June 1383) was the Byzantine emperor from 1347 to 1354.

Early life

Born in Constantinople, John Kantakouzenos was the son of Michael Kantakouzenos, governor of the Morea; Donald Nicol speculates that he may have been born after his father's death, and was brought up as an only child.^[1] Through his mother Theodora Palaiologina Angelina, he was a descendant of the reigning house of Palaiologos.^[2] He was also related to the imperial dynasty through his wife Eirene Asanina, a second cousin of Emperor Andronikos III Palaiologos.^[3] Kantakouzenos became a close friend to Andronikos III and was one of his principal supporters in Andronikos' struggle against his grandfather, Andronikos II Palaiologos. On the accession of Andronikos III in 1328, he was entrusted with the supreme administration of affairs. On the death of the emperor in 1341, John Kantakouzenos was left as the designated regent, and guardian of his son John V Palaiologos, who was nine years old.

John had no imperial ambitions of his own, and refused to be crowned co-emperor despite being offered the opportunity by Andronikos III Palaiologos several times during the reign of latter. After the death of the emperor, John again refused to take the throne, and insisted that the rightful heir was John V, and that he would assume administrative control of the Empire until he was of age. Despite his stalwart devotion to the young emperor and his mother the empress Anna of Savoy, his friendship with the late emperor had aroused both the jealousy of the Patriarch of Constantinople and his former protégé Alexios Apokaukos, and the paranoia of the empress who suspected him to be a usurper. When John Kantakouzenos left Constantinople for Morea, his enemies seized the opportunity to declare John V emperor and order the disbandment of Kantakouzenos's army. When news reached the army at Didymoteichon in Thrace, they declared Kantakouzenos emperor, and this marked the start of the civil war between John Kantakouzenos and the regency in Constantinople headed by Anna of Savoy, Apokaukos and the Patriarch.

The civil war which ensued lasted six years, during which the rival parties called in the aid of the Serbians, Bulgarians, and the Ottoman Turks, and engaged mercenaries of every description. It was only by the aid of the Ottoman Turks, with whom he made a bargain, that John VI Kantakouzenos brought the war to an end favorable to himself. He received sanctuary and was allied with Serbian Czar Dušan.^[4]

Reign

In 1347, he entered Constantinople in triumph with an army of 1,000 men, and forced his opponents to an arrangement by which he became joint emperor with John V Palaiologos and sole administrator during the minority of his colleague. His triumph in the six-year civil war is the subject of the poem "John Kantakouzenos Triumphs" by the modern Greek poet Constantine Cavafy.

He made his own son Matthew Kantakouzenos a co-emperor in 1353.

During this period, the empire, already broken up and reduced to narrow limits, was assailed on every side. There was an unsuccessful war with the Genoese, and in particular their colony at Galata, across from Constantinople itself. His later involvement in the Venetian–Genoese War of 1350–1355 also brought no concrete results, and was terminated by a treaty with Genoa in May 1352. War also erupted against the Serbians, who were at that time establishing an extensive empire on the north-western frontiers; and there was a hazardous alliance with the Ottoman Turks, who made their first permanent settlement in Europe, at Gallipoli in Thrace, towards the end of his reign. In 1349, he sent a newly built fleet of 9 fair-sized ships and about 100 smaller ones against the Genoese, but it was captured in its entirety. Then in 1351, he sent 12 ships to help Venice against Genoa, but the fleet was defeated.

Kantakouzenos was far too ready to invoke the aid of foreigners in his European quarrels; and as he had no money to pay them, this gave them a ready pretext for seizing upon a European town. The financial burdens imposed by him had long been displeasing to his subjects, and a strong party had always favoured John V Palaiologos. Hence, when the latter entered Constantinople at the end of 1354, his success was easy.

Retirement as a monk

Kantakouzenos retired to a monastery (where he assumed the name of Joasaph Christodoulos) and occupied himself in literary labors. He became the second Roman emperor to retire, after Diocletian.

In 1367 Joasaph was appointed the representative of the Eastern Orthodox Church to negotiate with the Latin Patriarch of Constantinople Paul to attempt a reconciliation of the Eastern Orthodox and Roman Catholic Churches. They agreed to call a grand ecumenical council to be attended by the Pope, all the Patriarchs and bishops and archbishops of both the eastern and western churches.^[5] This plan was subsequently refused by Pope Urban V and so nothing came of it.

He died in the Peloponnese and was buried by his sons at Mistra in Laconia.

Writings

His History in four books deals with the years 1320–1356. An apologia for his own actions, it needs to be read with caution; fortunately it can be supplemented and corrected by the work of a contemporary, Nikephoros Gregoras. It possesses the merit of being well arranged and homogeneous, the incidents being grouped around the chief actor in the person of the author, but the information is defective on matters with which he is not directly concerned. Kantakouzenos also wrote a defense of Hesychasm, a Greek mystical doctrine.

Family

By his wife Irene Asanina, a daughter of Andronikos Asan (son of Emperor Ivan Asen III of Bulgaria by Eirene Palaiologina, herself daughter of Emperor Michael VIII Palaiologos), John VI Kantakouzenos had several children, including:^[6]

1. Matthew Kantakouzenos, co-emperor 1353–1357, later Despot of the Morea
2. Manuel Kantakouzenos, Despot of the Morea
3. Andronikos Kantakouzenos (died 1347)
4. Maria Kantakouzene, who married Nikephoros II Orsini of Epirus
5. Theodora Kantakouzene, who married Sultan Orhan of the Ottoman Empire^[7]
6. Helena Kantakouzene, who married Emperor John V Palaiologos
