John V Palaiologos orPalaeologus (Greek:Ἰωάννης Παλαιολόγος,romanized: Iōánnēs Palaiológos; 18 June 1332 – 16 February 1391) wasByzantine emperor from 1341 to 1391, with interruptions. His long reign was marked by constant civil war, the spread of theBlack Death and several military defeats to theOttoman Turks, who rose as the dominant power of the region.
John V became emperor at age eight, which resulted in acivil war between his regentJohn VI Kantakouzenos and a rival council led by his motherAnna of Savoy, who pawned the crown jewels toVenice in order to raise funds. Kantakouzenos was recognized as emperor in 1347, coinciding with thearrival of the Black Death. Shortly after, anothercivil war erupted in 1352, with John V seeking help fromSerbia against John VI's sonMatthew and his enlistedOttoman Turks. The Turks used the ensuing chaos to gain their first European territory on former Byzantine soil.
John V assumed real power in 1354, removing John VI and his son Matthew. He attempted to gain Western support for the war against the Turks, resulting in his conversion to Catholicism in 1369 in presence of the Pope. These efforts were useless, as he was imprisoned in Venice due to his debts and was eventually forced to recognize Ottoman suzerainty. Political intriguing continued to plague his late reign; John was twice usurped from the throne, first by his sonAndronikos IV in 1376 and then by his grandsonJohn VII in 1390. He died in 1391 and was succeeded by his sonManuel, while his younger sonTheodore ruled theDespotate of the Morea.
John V was the son of EmperorAndronikos III and his wifeAnna,[4] the daughter of CountAmadeus V of Savoy by his wifeMaria of Brabant. His long reign was marked by the gradual dissolution of imperial power amid numerous civil wars and the continuing ascendancy of theOttoman Turks.
Victorious in 1347, John VI Kantakouzenos ruled as co-emperor until his sonMatthew Kantakouzenos was attacked by John V in 1352, leading to asecond civil war. John V asked the ruler of Serbia,Stefan Dušan for help, and Dušan obliged by sending 4,000 Serbian horsemen to his aid. Matthew Kantakouzenos asked his father for help, and 10,000 Ottoman Turks showed up at Demotika (Didymoteicho) in October 1352 and engaged the forces of John V's Serbian allies in anopen field battle that resulted in the destruction of the allies and a victory for the more numerous Turks in the service of the Byzantines. TheOttoman Empire thus acquired its first European territory, atÇimpe andGallipoli. Able to retake Constantinople in 1354, John V removed andtonsured John VI Kantakouzenos; by 1357, he had deposed Matthew as well, who had been captured by the Serbs and was ransomed to John V.
In 1366, John V reached theKingdom of Hungary, arriving at the Royal city ofBuda to meet KingLouis I of Hungary. However, the Byzantine emperor offended the king by staying on his horse, while Louis descended and approached him on foot. The Hungarian monarch then offered him help on the condition that John join the Catholic Church, or at least achieve recognition by the Patriarch of the Pope's supremacy. The Emperor left the court of Buda with empty hands and continued his trip through Europe searching for assistance against the Ottomans.[5]
The Ottomans, who had been allied with the Kantakouzenoi, continued to press John.Suleyman Paşa, the son of the Ottoman sultan, led their forces in Europe and was able to takeAdrianople andPhilippopolis and to exact tribute from the emperor. John V appealed to the West for help, proposing toPope Urban V in 1367 to end theschism between theByzantine andLatin churches by submitting thepatriarchate to the supremacy of thePope. In October 1369, John, having travelled through Naples to Rome, formally converted to Catholicism in Saint Peter's Basilica and recognized the Pope as supreme head of the Church.[6] He was not accompanied by the clergy of the Byzantine Church and the move failed to bring about an end to the Schism.[7] He became the last Byzantine emperor (the first since emperorConstans II' visit in 663) to make a visit to Rome.
Impoverished by war, he was detained as a debtor when he visitedVenice in 1369 on his way back from Rome and was later captured on his way back through Bulgarian territories. In 1371, he recognized the suzerainty of the Ottoman sultanMurad I. Murad later assisted him against his sonAndronikos when the latterdeposed him in 1376.
In 1390, his grandsonJohn VII briefly usurped the throne, but was quickly overthrown. The same year, John V ordered the strengthening of theGolden Gate in Constantinople, utilizing marble from the decayed churches in and around the city. Upon completion of this construction,Bayezid I demanded that John raze these new works, threatening war and the blinding of his son Manuel, whom he held in captivity. John V carried out the Sultan's order but is said to have suffered from this humiliation and died soon thereafter on 16 February 1391, and was buried in theHodegon Monastery in Constantinople.[8]
John V was finally succeeded to the imperial throne by his sonManuel. His younger sonTheodore had already acceded to theDespotate of Morea in 1383.

^"...in the presence of four cardinals, he acknowledged, as a true Catholic, the supremacy of the Pope, and the double procession of the Holy Ghost. After this purification, he was introduced to a public audience in the church of St. Peter: Urban, in the midst of the cardinals, was seated on his throne; the Greek monarch, after three genuflections, devoutly kissed the feet, the hands, and at length the mouth, of the holy father, who celebrated high mass in his presence, allowed him to lead the bridle of his mule, and treated him with a sumptuous banquet in the Vatican." –Edward Gibbon,The History of the Decline and Fall of the Roman Empire,Chapter 66 (Visit of John Palaeologus to Urban V. at Rome, A.D. 1369, 13 October etc.), via theChristian Classics Ethereal Library
