Palaiologos

Michael VIII Palaiologos (r. 1259–1282), founder of the imperial Palaiologos dynasty

Michael Palaiologos, born in 1223, was the son of Andronikos Palaiologos, megas domestikos in the Empire of Nicaea. Through the preceding century or so of Palaiologan marriages to other imperial families, his ancestry could be traced back to the three most recent dynasties that had ruled the empire before the Fourth Crusade (Doukas, Komnenos and Angelos).[6] In his youth, Michael had served as the governor of the towns of Melnik and Serres in Thrace, and though he and his family were distinguished among the aristocracy, he was frequently mistrusted by the ruling Laskaris dynasty. In 1253, Emperor John III Doukas Vatatzes accused him of plotting against the throne, though Michael escaped the accusation without punishment following a trial by ordeal of holding a red-hot iron.[7] Though Michael continued to be mistrusted even after this, he married John III's grandniece Theodora Vatatzaina and was appointed as the megas konostaulos of the Latin mercenaries employed by the empire.[8]

After John III's death in 1254, Michael briefly took service with the Seljuk Sultanate of Rum, frequent enemies of the empire, and from 1256 to 1258 he was the commander of the Christian mercenaries fighting for the Seljuk Sultan Kaykaus II. John III's son and successor, Theodore II Laskaris, recalled Michael in 1258 and after they had exchanged guarantees of safety and oaths of loyalty, Michael returned to service within the empire.[8] Theodore II died in that same year and was succeeded by his eight-year-old son John IV Laskaris. Just a few days after Theodore's death, Michael led a coup against the bureaucrat George Mouzalon,[9] who had been appointed regent by Theodore II.[1] Michael seized the guardianship of the child emperor and was invested with the titles of megas doux and despotes. On 1 January 1259, Michael was proclaimed as co-emperor at Nymphaion, probably without John IV being present.[9]

On 25 July 1261, Nicene forces under general Alexios Strategopoulos recaptured Constantinople from the Latin Empire, restoring the city to Byzantine rule after almost sixty years in foreign hands.[10] After the recapture of the capital and the restoration of the Byzantine Empire, Michael took care to be crowned emperor in Hagia Sophia, as Byzantine emperors had been before the city was lost to the crusaders. John IV, the last representative of the imperial Laskaris dynasty, was pushed aside in order to consolidate the Palaiologos family on the throne.[1] On John IV's eleventh birthday, 25 December 1261, the boy was deposed, blinded and confined to a monastery.[11] Once news of the act, the blinding of not only the legitimate emperor, but an underage boy, got out, the Patriarch of Constantinople, Arsenios Autoreianos, excommunicated Michael. The emperor's excommunication was not lifted until nine years into his reign, upon the appointment of Patriarch Joseph I.[12] The blinding of John IV was a stain on the Palaiologan dynasty. In 1284, Michael's son and successor Andronikos II Palaiologos visited the blinded and then 33-year-old John IV during a journey in Anatolia, hoping to demonstrate his disapproval with his father's actions.[1]

Imperial banner adopted by the Palaiologos dynasty in the 14th century

The Palaiologoi ruled Byzantium at its weakest point in history, and the empire underwent significant economical and political decline. Even in this state, the empire, famous for its frequent civil wars, was unable to stay united. In 1320, Emperor Andronikos II Palaiologos attempted to disinherit his grandson Andronikos III Palaiologos, despite the death of Andronikos II's son, heir and co-emperor Michael IX Palaiologos (Andronikos III's father). Andronikos III secured the support of a significant number of the aristocracy and a period of civil war, not ended until 1328, ensued. Although Andronikos III was ultimately victorious and Andronikos II was deposed, the empire was damaged economically and for the first time, foreign states such as Bulgaria and Serbia had appeared as significant regulating factors in imperial dynastic disputes (joining opposite sides of the civil war).[1]

John VI Kantakouzenos (center, r. 1347–1354) nearly succeeded in deposing the Palaiologos dynasty in favor of his own family, the Kantakouzenoi.

When Andronikos III died in 1341, his underage son John V Palaiologos inherited the throne. Disputes between John V's mother Anna of Savoy and the Patriarch John XIV on one side and Andronikos III's friend and megas domestikos John Kantakouzenos on the other led to a new and devastating civil war, lasting until 1347 and won by John Kantakouzenos, who became senior co-emperor as John VI. The weakening of Byzantium as a result of the civil war allowed Stefan Dušan of Serbia to invade Macedonia, Thessaly and Epirus in 1346–1348, creating the Serbian Empire. In the meantime, John VI Kantakouzenos attempted to consolidate his own dynasty on the imperial throne, marrying his daughter Helena to John V and proclaiming his son Matthew Kantakouzenos as co-emperor. Clearly intending to usurp the throne, a new series of civil wars from 1352 to 1357 were eventually won by John V, deposing the Kantakouzenoi. In 1382, the Kantakouzenoi were also driven out of the Morea (the modern-day Peloponnese) and John V's son Theodore was placed to govern it as the semi-independent Despot of the Morea, an important victory as the region was quickly becoming the most important Byzantine province. The Byzantine civil wars, and the collapse of Stefan Dušan's Serbian Empire following his death in 1355, had allowed the Ottoman Turks to expand almost unopposed through the Balkans and in the second half of the 14th century, the empire passed almost without a fight under Ottoman sovereignty, forced to pay tribute and offer military aid if needed.[1]

In 1373, John V's son and heir Andronikos IV Palaiologos rebelled against his father in an attempt to seize the throne, instigating a fourth series of Palaiologan civil wars. John V was initially victorious, imprisoning and disinheriting Andronikos IV and appointing a younger son, Manuel II Palaiologos, as his successor instead. However, Andronikos eventually escaped from prison and successfully took the throne in 1376 with aid from Genoa, imprisoning his father and his younger brother. John V retook the throne in 1379 but reached an agreement with Andronikos in 1381, wherein Andronikos was to succeed him as emperor, passing over Manuel. Andronikos died in 1385 and his son, John VII Palaiologos briefly managed to usurp the throne in 1390. Following this, Manuel II was firmly established as John V's successor, becoming senior emperor upon John's death in 1391.[1]

Though most of the Palaiologan era was defined by decline and war, it was also an age of cultural flourishing, beginning in the late 13th century. Advances in science and the arts, referred to as the Palaiologan Renaissance, lasted throughout the dynasty's rule, encouraged by the efforts of some emperors such as Andronikos II and Manuel II.[1]

Constantine XI Palaiologos (r. 1449–1453), the final Byzantine Emperor

By the 15th century, the Byzantine emperors had lost any real power, with the Ottoman sultans increasingly becoming the real regulators of political matters within the empire.[1] Despite their de facto submission under the Ottomans, the Byzantines continued to act with hostility against them. In 1394, Manuel II ceased to pay tribute to the Ottoman sultan Bayezid I, who responded by besieging Constantinople.[13] Bayezid's siege lasted for more than a decade, with Western aid through the Crusade of Nicopolis (1396) failing to stop the sultan. The situation was so dire that Manuel left Constantinople to travel around Western Europe asking for further aid against the Ottomans, visiting Italy, France and England.[14] Ultimately, the siege was resolved peacefully by Manuel through signing a peace treaty with Bayezid's son and successor, Mehmed I, in 1403, which among other things returned the city of Thessaloniki, captured by the Ottomans in 1387, to Byzantine rule.[15]

There was peace between the Palaiologans and the Ottomans until 1421, when Mehmed I died and Manuel retired from state affairs, to pursue scholarly and religious interests. Manuel's son, John VIII Palaiologos, co-emperor since before 1416, ignored the fragile peace with the Ottomans and supported Mustafa Çelebi, a pretender to the Ottoman throne, in a rebellion against Mehmed I's successor Murad II. Murad defeated Mustafa's rebellion and besieged Constantinople in 1422, though the Byzantines successfully repulsed him.[15] Even during the final decades of the Byzantine Empire, the Palaiologoi often found it difficult to cooperate with each other. During Manuel II's reign, John VIII and the younger son Constantine appear to have got on well with each other, but the relations between Constantine and the younger brothers Demetrios and Thomas were not as friendly.[16]

Through most of John VIII's reign, Constantine and Thomas ruled as Despots of the Morea, with Demetrios governing a stretch of land in Thrace.[17] Demetrios was unhappy with his subordinate position and assaulted Constantinople in 1442, with Ottoman help, in an attempt to seize the city and become emperor himself.[17] John VIII, aided by Constantine, successfully repulsed this attack and Demetrios was briefly imprisoned as punishment.[18] After John VIII's death in June 1448, the candidates for the throne were brothers Constantine, Demetrios and Thomas. To avoid infighting, their mother Helena Dragaš decided that Constantine was to be the next emperor. Constantine XI Palaiologos's rise to the throne was also accepted by Murad II, who by now had to be consulted for any appointments.[19]

Constantine XI's reign would prove to be brief. Murad II's young son and successor, Mehmed II, who became sultan in 1451, was obsessed with the idea of conquering Constantinople.[20] In an effort to extort money from Mehmed, Constantine implicitly threatened to release Orhan Çelebi, Mehmed's cousin and the only other known living member of the Ottoman dynasty (and as such a potential rival to Mehed), who was held prisoner in Constantinople.[21] The ill-advised threat gave Mehmed a casus belli and late in 1451, preparations were already underway for a new Ottoman siege of Constantinople.[22] To prevent aid coming from the Morea, now governed by Thomas and Demetrios, Mehmed II sent one of his generals, Turahan Bey (who had raided the Morea twice before) to devastate the peninsula.[23] Constantine also sent desperate pleas for aid to Western Europe, though little help ever arrived.[22] After a 53-day long siege, the city finally fell to the Ottomans on 29 May 1453. Constantine XI died fighting in its defense.[24]

Thomas Palaiologos, younger brother of Constantine XI and Despot of the Morea 1428–1460

In the aftermath of Constantinople's fall, one of the most pressing threats to the new Ottoman regime was the possibility that one of Constantine XI's relatives would secure support and return to reclaim the empire. However, it soon became apparent Constantine's closest relatives, his brothers in the Morea, represented little more than a nuisance to Mehmed II and they were thus allowed to keep their titles and lands as Ottoman vassals.[24] Under their rule, the Morea was transformed into somewhat of a Byzantine government-in-exile, as Byzantine refugees from Constantinople and elsewhere fled to their courts, some even wishing to proclaim Demetrios, the elder brother, as Constantine's successor and the new Emperor and Autocrat of the Romans.[25] The brothers were divided in their policies. Thomas retained hope that the Papacy might yet call for a crusade to restore the Byzantine Empire whereas Demetrios, probably the more realistic of the two, had more or less given up hope of Christian aid from the West and believed it to be best to placate the Turks.[23]

In January 1459, rivalry between the brothers broke out into civil war as Thomas, with the aid of some of the Albanian lords in the Morea, seized a series of fortresses held by Demetrios.[26] The ongoing civil war, and the possibility that Thomas could receive aid from the West since he had proclaimed the war against his brother as a holy war against the muslims, caused Mehmed to invade the Morea in 1460.[27][28] Mehmed was victorious and annexed the region directly into the Ottoman Empire, ending Palaiologan rule in Greece. Demetrios surrendered to the Ottomans without a fight and Thomas escaped into exile.[28] Demetrios lived in the Ottoman Empire for the rest of his life, dying in 1470. His only child, his daughter Helena, never married the sultan nor entered the sultan's harem, possibly because the sultan feared that she would poison him. She predeceased her father, dying in 1469.[29]

Thomas had four children; Helena, Zoe, Andreas and Manuel. Helena had already been married to Lazar Branković, the Despot of Serbia, but the three younger children, and Thomas's wife Catherine Zaccaria, and a retinue of other refugees, accompanied him as he escaped to the Venetian-held island of Corfu. The local authorities on Corfu were not eager to house the despot out of fear of provoking the Ottomans,[30] so Thomas soon left the island and travelled to Rome, hoping to convince Pope Pius II of calling for a crusade against the Ottomans.[31] Though Pius II was eager to go through with the idea, and Thomas rode around Italy in the hopes of drumming up support for the venture,[32] no crusade materialized this time either.[32] Thomas died on 12 May 1465 and shortly thereafter Zoe, Andreas and Manuel arrived in Rome.[33]

In Rome, the three children were taken care of by Cardinal Bessarion, also a Byzantine refugee. In 1472, according to Bessarion's plans, Zoe (whose name was later changed to Sophia) was married to Duke Ivan III of Moscow.[34] As the oldest son, Andreas was recognized by the Papacy as Thomas's heir and the rightful Despot of the Morea.[35] From the 1480s onwards, Andreas also claimed the title Imperator Constantinopolitanus ('Emperor of Constantinople'). Some Byzantine refugees, such as historian George Sphrantzes, recognized Andreas as the rightful heir of the old emperors.[35] Andreas and Manuel soon faced financial problems, with the pension once provided to their father having been split between the two of them and constantly cut back by the Papacy. Andreas attempted to sell his claims to various Byzantine titles to earn money, but since Manuel did not have any claims to sell (as he was the second son), he instead travelled around Europe hoping to enter into the service of some noble. After not receiving any satisfactory offers, Manuel surprised the establishment in Rome by travelling to Constantinople in 1476 and presenting himself before Sultan Mehmed II. The sultan generously received him and Manuel stayed in Constantinople for the rest of his life.[36]

Andreas died poor in Rome in 1502.[37] Whether he had any children is uncertain. It is possible that a Constantine Palaiologos, employed in the Papal Guard and dead in 1508 was his son.[38][39] According to Russian sources, he might also have had a daughter, Maria Palaiologina, who married a Russian prince.[38] A Fernando Palaiologos, referred to as the "son of the Despot of the Morea" by Ludovico Sforza, Duke of Milan, in 1499 might also have been a son of Andreas.[40] Andreas's brother Manuel died in Constantinople at some point during the reign of Mehmed II's son and successor Bayezid II (r. 1481–1512).[41] Manuel had two sons; John Palaiologos, who died young, and Andreas,[42] probably named after Manuel's brother.[43] Manuel's son Andreas converted to Islam and might have served as an Ottoman court official.[44] He is last attested in the reign of Suleiman the Magnificent (r. 1520–1566)[45] and is not believed to have had children of his own.[46] Thus, the male line of the imperial branch of the House of Palaiologos probably went extinct at some point in the early 16th century.[38]

In order to conserve space, the family tree only displays people of male-line descent who survived until adulthood (with the exception of co-emperor Andronikos V Palaiologos, who died a child). The Montferrat cadet branch (descendants of Theodore, son of Emperor Andronikos II) is not shown. Emperors are indicated with bold text and women are indicated with italics. Dotted lines indicate illegitimate offsprings.[47]

Although the imperial dynasty went extinct in the male line, descendants of the Palaiologan emperors survived for centuries through the lineages of various daughters. Thomas Palaiologos's oldest daughter, Helena, married Lazar Branković, Despot of Serbia, with whom she had three daughters; Jelena, Milica and Jerina Brankovic.[48] Jelena died childless, but Milica married Leonardo III Tocco, the ruler of the Despotate of Epirus.[49][50] When the despotate fell to the Ottomans in 1479, Leonardo and his family escaped to Italy, where he continued to be recognized as the titular Despot of Epirus.[51] Milica and Leonardo had a son; Carlo III Tocco, who succeeded Leonardo as the titular despot.[49] The Tocco family, male-line descendants of Leonardo III and Milica Branković styled themselves as princes on the ground that they represented not only the senior descendants of the Byzantine imperial dynasty, but of the Serbian royal dynasty as well. Additionally, they continued to style themselves as despots of Epirus until the 17th century, when they instead began to title themselves as princes of Achaea.[52] The change in title might be attributable to the family being the senior heirs of Thomas Palaiologos, whose wife had been the heiress of the last Prince of Achaea.[53] The Tocco family went extinct in 1884, with the title of Prince of Achaea (among others) being inherited by Carlo Capece Galeota, their closest relative.[53][54] Carlo died in 1908 and his only child, his daughter Maria Maddalena, died in 1933.[54] The most senior descendants of the Tocco family alive today is the Italian Serra family, dukes of Cassano, owing to the 1798 marriage of Guiseppe Serra di Cassano and Teresa Tocco Cantelmo Stuart, daughter of one of the titular Tocco princes of Achaea.[55]

Lazar Branković's third daughter, Jerina, married Gjon Kastrioti II, the son of Albanian national hero Skanderbeg. The modern Castriota family, living in Italy, are the only known living descendants of Jerina and Gjon Kastrioti II.[56]

The marriage of Zoe/Sophia (Thomas's second daughter) to Ivan III of Moscow served to strengthen Moscow's claim to be the "Third Rome", the ideological and spiritual successor to the Byzantine Empire. Sophia and Ivan had several children and numerous descendants. Though the Palaiologos name was not passed on, many of them used the double-headed eagle iconography of Byzantium. The famous Ivan the Terrible (r. 1547–1575), Russia's first Tsar, was Sophia's grandson.[48] The Romanov dynasty, which succeeded Ivan the Terrible's Rurik dynasty and ruled Russia from 1613 to 1917, were not descended from Sophia, originating as in-laws, rather than descendants, of the Rurikids.[57]

Thomas's older brother Theodore II, who preceded him (and co-ruled with him for a time) as Despot of the Morea, had a daughter, Helena, who married King John II of Cyprus. Their only child to survive until adulthood, Charlotte, died childless in 1487.[58]

When the Byzantines reconquered Constantinople in 1261 under Michael VIII Palaiologos, the Papacy suffered a loss of prestige and endured severe damage to its spiritual authority. For 57 years, Constantinople had been under Catholic rule through the Latin Empire and now the easterners had once more asserted their right not only to the position of Roman emperor but also to a church independent of the one centered in Rome. The Popes in the immediate aftermath of the Latin Empire's fall pursued a policy of attempting to assert their religious authority over the Byzantine Empire. Some Western pretenders who wished to restore the Latin Empire, such as the King of Sicily, Charles of Anjou, periodically enjoyed Papal support,[59] and several Popes considered the idea of calling for a new crusade against Constantinople to once more impose Catholic rule.[60]

Michael VIII succeeded in achieving a union of the Catholic and Orthodox churches at the Second Council of Lyons in 1274, legitimizing him and his successors as rulers of Constantinople in the eyes of the West.[61] Michael's son and successor Andronikos II wished to further legitimize the rule of the Palaiologan dynasty. Other crusader states had been formed in Greece as a result of the Fourth Crusade, notably the Kingdom of Thessalonica, which had been ruled by the Aleramici family of Montferrat. In an effort to rid himself of the threat that an Aleramici pretender might launch an invasion and attempt to seize Thessaloniki in the future, Andronikos married Yolande of Montferrat in 1284, bringing her dynastic claims to Thessaloniki into his own family line.[62] Since Yolande was second-in-line to the throne of the March of Montferrat, the marriage had the unexpected result of creating the possibility that a Byzantine prince might inherit Montferrat. When Yolande's brother, John I of Montferrat, died without children in 1305, Montferrat legitimately passed to Yolande and her children.[63]

The Byzantine aristocracy were less than eager of sending one of Andronikos II's sons to claim Montferrat. That a Byzantine prince, born in the purple, would be sent to live among, and rule over, Latin barbarians,[64] was bad enough but there were also fears that he and his descendants might become 'Latinized'[65] and that the Italians, as a result of the Montferrat inheritance, could launch an invasion in the future in hopes of placing a Catholic Palaiologos on the Byzantine throne.[66] In the end, Andronikos II's fourth son (in order to not jeopardize the line of succession),[67] Theodore, was chosen to travel to Montferrat, arriving there in 1306.[68] Byzantine fears of Latinization became true; Theodore converted to Catholicism and on his visits to Constantinople, Theodore schocked the Byzantines with his shaven face and Western customs.[69]

Theodore's descendants, the Palaeologus-Montferrat family, ruled at Montferrat until the 16th century, though they were sometimes given Greek names, such as Theodore and Sophia,[70] most of the Palaiologan Marquises of Montferrat paid little attention to affairs in the eastern Mediterranean.[71] The only Marquis to seriously consider using his Byzantine connection was Theodore's son, John II of Montferrat, who wished to take advantage of the Byzantine civil war of 1341–1347, between Andronikos II's great-grandson John V and John VI Kantakouzenos, in order to invade the empire and conquer Thessaloniki. In his will from 1372, John II claimed that Andronikos II's deposition in 1328 by his grandson Andronikos III (John V's father) had been unlawful and thus disqualified Andronikos III and all his heirs from the legitimate line of succession to the throne of Byzantium. John II also pointed out that since Andronikos II had disinherited Andronikos III, John II was thus the rightful emperor as the only true heir to Andronikos II.[69] John II even petitioned the Papacy to recognize his claims to Thessaloniki and to the empire, and to help him conquer them.[72] An expedition to "recover" these territories was never organized.[65]

Coat of arms of the Paleologo-Oriundi, living descendants of an illegitimate son of the marquis John George Palaeologus (d. 1533)

The final Palaeologus Marquis, John George, Marquis of Montferrat, died in 1533 and rule of Montferrat was then given to Federico II Gonzaga, Duke of Mantua, by Holy Roman Emperor Charles V.[73] The last female member, Margaret Paleologa, married to Federico II, died in 1566, rendering the Montferrat cadet branch extinct. Her and Federico II's descendants, with the Gonzaga name, ruled Montferrat until they were supplanted by the House of Savoy, which had also intermarried with the Palaeologus-Montferrat family in the past, in the 18th century.[74] The name "Montferrato-Paleologo" is recorded on the Greek island of Cephalonia until the 17th century, though it is uncertain how they were connected to the Italian family.[75] A modern lineage, called the Paleologo-Oriundi, descends from Flaminio, an illegitimate son of John George.[76][77][78]

The probable extinction of the senior branch of the imperial Palaiologos family at some point in the 16th century did little to stop individuals in various parts of Europe from claiming descent from the old imperial dynasty.[38] The family name Palaiologos had been relatively widespread in the Byzantine Empire, and the family had been quite extensive before a branch of it acceded to the imperial throne.[79] Many of the non-imperial Byzantine Palaiologoi were part of the nobility and served as generals or powerful landowners.[80] In addition to the non-imperial Palaiologoi that were descendants of older collateral lines, Byzantine genealogy is also made complicated by the fact that it was common in Byzantium to adopt the family name of your spouse or mother, if that was more prestigious.[78]

Many Byzantine nobles found themselves in Constantinople in 1453, fighting against the Ottomans in their final attack. Some, such as Theophilos Palaiologos, lost their lives in the battle, whereas others were taken prisoner and executed. Nobles that could escape mostly did, many fleeing to the Morea where they had estates. There, they faced a dilemma. The Byzantine Empire had fallen and the rulers of the Morea, Thomas and Demetrios, appeared more interested in their own rivalry than in organizing resistance against the Ottomans. As such, many of them escaped into Western Europe either before or after the Morea fell in 1460.[80]

Many Byzantine refugees, though unrelated to the emperors, legitimately bore the name Palaiologos due to the extensive nature of the family. Because the name could lend whoever bore it prestige (as well as possible monetary support), many refugees fabricated closer links to the imperial dynasty. Many Western rulers were conscious of their failure to prevent Byzantium's fall and welcomed these men at their courts.[79] The refugees were helped in that many in Western Europe would have been unaware of the intricacies of Byzantine naming customs; to Western Europeans, the name Palaiologos meant the imperial dynasty.[81] Though such Palaiologoi, imperial or not, were mainly concentrated in northern Italy, such as in Pesaro, Viterbo or Venice, other Greek refugees travelled across Europe, many ending up in Rome, Naples, Milan, Paris or in various cities in Spain.[79][82]

'Palaiologos' as a last name continues to survive to this day in various variants. Common versions of the last name used today include the standard Palaiologos (approximately 1,800 people, most common in Greece),[83] Palaiologou (approximately 2,000 people, again most common in Greece),[84] Paleologos (approximately 500 people, most common in the United States but present worldwide)[85] and Paleologo (approximately 250 people, most common in Italy).[86] These modern Palaiologoi cannot be confidently proven to descend from the imperial dynasty, or the medieval family which produced it.[87] Because people with the name live throughout the world and might not even be related in the first place, creating an all-encompassing modern Palaiologos genealogy is next to impossible.[78]

It is possible that many of the modern people who bear the name are descended from wealthy Greeks in the Ottoman period, who commonly assumed Byzantine surnames and claimed descent from the famous noble houses of their Byzantine past.[87][88] Some might be genuine descendants of the imperial family as several of the imperial Palaiologoi are recorded as having had illegitimate children; for instance, Theodore II, Despot of the Morea, is known to have had several illegitimate children.[88]

Coat of arms of Theodore Paleologus (d. 1636)

The Paleologus family in Pesaro, attested from the early 16th century onwards, claimed descent from 'John Palaiologos', a purported third son of Thomas Palaiologos. Their genealogy mainly derives from the tombstone of Theodore Paleologus (d. 1636), which lists Theodore's male-line ancestors five generations back, reaching Thomas.[89] With the sole exception of Thomas's purported son John, the existence of the rest of Theodore's immediate ancestors can be verified through records at Pesaro.[90] The earliest record of John's existence other than Theodore's tombstone are the writings of the Greek scholar Leo Allatius, who wrote in 1648, too late for his works to be considered independent evidence. Allatius was the keeper of the Vatican Library and would have had access to its vast collection of books and records and might have deduced his findings from there.[91] As such, it is possible that Allatius had access to earlier documents, now lost, which would have proven the legitimacy of the Pesaro line. Allatius gives the sons of Thomas as "Andrea, Manuele and Ioanne".[92] It would be difficult to explain why Allatius, a respected scholar, would simply make up a member of an ancient dynasty.[93] The absence of any mentions of John Palaiologos in contemporary sources means that the Paleologus family's status as genuine male-line descendants of the last few Byzantine emperors can not be proven, but it is not impossible. None of their own contemporaries appear to have doubted their imperial descent.[94]

Tombstone of Ferdinand Paleologus (d. 1670) in Barbados

In 1578, the members of the family living in Pesaro were embroiled in a scandal as brothers Leonidas and Scipione Paleologus, and their nephew Theodore, were arrested for attempted murder.[95] What happened to Scipione is not known, but Leonidas was executed. On account of his young age, Theodore was exiled from Pesaro rather than executed.[96] Following his exile, Theodore established himself as an assassin and appears to have garnered an impressive reputation.[97] In 1599, he entered into the service of Henry Clinton, the Earl of Lincoln, in England.[98] Theodore lived in England for the rest of his life and fathered six children,[99] whose fates were caught up in the English Civil War of 1642–1651. His son Ferdinand Paleologus, escaping the war, settled on the recently colonized island of Barbados in the Caribbean, where he became known as the "Greek prince from Cornwall" and owned a cotton or sugar plantation.[100][101]

Ferdinand died in 1670 and was survived only by his son, Theodore.[102] Theodore left Barbados to work as a privateer, serving aboard a ship called Charles II, and died at A Coruña, Spain in 1693.[103] Theodore had a son, who probably predeceased him,[104] and was survived only by a posthumous daughter, Godscall Paleologue, born in January 1694.[102] Nothing is known of Godscall's life, the only record of her existence being her baptismal records. She was the last recorded member of the family and, if their claim to descend from the imperial dynasty was true, the last true heir of the Palaiologan emperors.[105][106][39]

Possible portrait of Theodore Palaiologos (d. 1532), stratiote in the service of Venice

Because Venice was the only major non-Muslim power in the Eastern Mediterranean, it represented an appealing destination for Byzantine refugees as the empire fell.[80] Numerous people with the last name Paleologus are recorded in Venice in the 15th and 16th centuries, many serving as stratioti (mercenary light-armed cavalrymen of Greek or Albanian origin). Venetian documents frequently refer to their "strenuous" prowess in service to the Venetian Republic.[79] Venice had first become interested in hiring stratioti after witnessing the prowess of Greek and Albanian soldiers in the First Ottoman–Venetian War of 1463–1479.[107]

The Venetian Palaiologoi were not related to the imperial family, but they might have been distant cousins. One of the earliest references to Palaiologoi in Venice is a 1479 Senate decision concerning Theodore Palaiologos, who had recently proven himself in a campaign in Friuli.[108] Theodore had a well-documented career as a stratiote.[79] Born in 1452,[109] and probably originally from Mystras in the Morea,[79] Theodore was originally a debt collector for the Ottomans in the Morea. In 1478, Theodore travelled to Venice with his father, Paul, and became a stratiote. For his merits in the service of Venice, Theodore was granted the island Cranae, though he later ceded it to another family. In 1495, Theodore partook in a siege of Novara and also partook in later battles in Savona and Cephalonia. Due to his knowledge of the Turkish language, Theodore also accompanied Venetian ambassadors in diplomatic missions to the Ottoman Empire, visiting Constantinople several times.[109] He died in 1532,[79] being buried in the Orthodox church of San Giorgio dei Greci.[109]

Theodore had married Maria, a daughter of a man by the name Demetrios Kantakouzenos. That he could marry a genuine member of the noble Kantakouzenos family indicates that he held a certain noble status.[108] Theodore was one of the key players in the Greek community in Venice, having helped the Greek refugees there achieve permission to construct the San Giorgio dei Greci church in the first place, and his family was highly regarded by the locals.[110] Theodore's descendants and relatives lived on in Venice and its territories long after his death. His nephew, Zuanne Paleologo, and two of Zuanne's sons, died on Cyprus, fighting the Ottomans during the 1570 Siege of Nicosia in the Fourth Ottoman–Venetian War.[111] The 1570 will of Demetri Paleologo, a son of Theodore, begins with "Io Demetri Palleollogo, da Constantinopoli ...". Over a century had passed since Constantinople, a city Demetri had never seen, had fallen and yet he retained lingering dreams of the city.[112]

A man by the name Andrea Paleologo Graitzas, attested in Venice in 1460, supposedly has living descendants, with numerous people with the last name Palaiologos (or variations thereof) living in Athens today claiming to descend from him.[79]

In addition to the John Palaiologos of the Pesaro genealogy, some Italian genealogies from the 17th century onwards ascribe further sons to Thomas Palaiologos, notably a supposed older son by the name Rogerio or Ruggerio. According to the genealogies, Rogerio would have been born about 1430 and was supposedly sent to Alfonso the Magnanimous of Aragon and Naples as a hostage to guarantee some treaty with the Byzantines. Supposedly, he is to have stayed in Casalsottano, a hamlet of the Italian comune San Mauro Cilento, in a 15th-century building commonly referred to as the Palazzo ("the palace"). His stay in Casalsottano is said to have attracted Byzantine refugees of other families, such as the Notaras and Komnenoi, to the hamlet in the aftermath of Constantinople's fall, and together they supposedly erected the Spirito Santo church, which still stands today. Rogerio was purportedly a judge and is said to have died in 1488,[113] survived by his wife Antonia and his two children John (or Giovanni) and Angela.[114]

Supposedly, Rogerio's descendants would then have remained in Casalsottano until 1571, when Giovanni Paleologo was given the fief of Perito and Ostigliano in Salerno.[113] Giovanni's descendants then supposedly remained in Salerno, where they gave rise to the modern (and extant) Paleologo Mastrogiovanni (or just Mastrogiovanni) family, named in his honour.[115] This family history derives mainly from oral tradition, with only a handful of documents possibly verifying parts of it as true. There is a document from Casalsottano, dated 24 June 1441, which bears the signature of "Ruggerio Greco", "Greco" interpreted by proponents of the Mastrogiovanni descent as a nickname due to his Greek origin rather than a surname. A 1455 document in which Cardinal Isidoro Ruteno grants indulgences to those who donate to a church in San Mauro Cilento mentions a "Ruggerio" as the son of "Tommaso Paleologo". A 1463 document supposedly signed by King Ferdinand I of Aragon records the granting of some lands in the vicinity of San Mauro to Rogerio, son of "illustrissimi Thomae Palaeologi dispoti Moreae". Though most of these documents do not appear questionable in of themselves, they have not been authenticated and there are several problems with the overall reconstruction of events and descent.[116]

In modern scholarship, Rogerio's existence is overwhelmingly dismissed as fantasy.[117] The potential Palaiologan heir being kept as a hostage in Italy agrees poorly with contemporary Byzantine-Aragonese relations and importantly, no Byzantine historians mentions his existence. The contemporary historian George Sphrantzes, who described the life of Thomas Palaiologos in detail, wrote on the birth of Andreas Palaiologos on 17 January 1453 that the boy was "a continuator and heir" of the Palaiologan lineage, a phrase which makes little sense if Andreas was not Thomas's first-born son.[118] The "Rogerio Greco" mentioned as a judge in 1441 cannot be identified with the supposed progenitor of the Paleologo Mastrogiovanni line since it would have been impossible for him to have been a judge at only 11 years old.[119] A 1489 census of San Mauro Cilento records no inhabitants with Byzantine surnames, though records a widow and daughter of "Quondam Princi de Rogerio Greco", someone subsequent censuses make clear left no further descendants.[120] The presence of double-headed eagle symbols in the Spirito Santo church has been used as an argument in the past, but this symbol was not unique to the Palaiologoi, being used as a symbol by other families as well (both Byzantine and Western).[120]

Signature of Hass Murad Pasha, an Ottoman statesman and possibly illegitimate son of one of Constantine XI's brothers

Some nobles with the last name Palaiologos remained in Ottoman Constantinople, and even prospered in the immediate post-conquest period. In the decades after 1453, Ottoman tax registers show a consortium of noble Greeks co-operating to bid for the lucrative tax farming district including Constantinople and the ports of western Anatolia. This group included names like "Palologoz of Kassandros" and "Manuel Palologoz".[121][122] This group stood in close contact with two powerful viziers, Mesih Pasha and Hass Murad Pasha, both of whom were reportedly nephews to Constantine XI Palaiologos and had been forced to covert to Islam after Constantinople's fall,[123] as well as with other converted scions of Byzantine and Balkan aristocratic families like Mahmud Pasha Angelović, forming what the Ottomanist Halil İnalcık termed a "Greek faction" at the court of Mehmed II.[121]

Maurice Paléologue (d. 1944), a French diplomat of Romanian origin who claimed descent from the Palaiologan dynasty

Numerous people with the last name Palaiologos, living on the island of Syros in Greece, have historically claimed descent from a supposed son of Andronikos Palaiologos, one of Emperor Manuel II's sons and Despot of Thessaloniki.[75] Their descent is questionable since there is no surviving contemporary evidence that Andronikos had children. That Andronikos suffered from elephantiasis and epilepsy, and that he died at a young age, makes it unlikely that he married and had a son.[115]

Another family which claims to descend from the old imperial dynasty are the Paleologu of Romania, claiming to be the descendants of an otherwise unattested son of Theodore II Palaiologos, Despot of the Morea, called Emanuel Petrus (Manuel Petros in Greek). The Paleologu also live in Malta and France, one of the most famous members of the family being the French diplomat Maurice Paléologue, who in his lifetime repeatedly asserted his imperial descent.[75] The ancestry of the Paleologu can be traced to Greeks with the name Palaiologos, but not to the imperial family. In the 18th century, several Phanariots (members of prominent Greek families in the Fener quarter of Constantinople) were granted governing positions in the principalities of Wallachia and Moldavia (predecessors of Romania) by the Ottomans. The Phanariots sent to Wallachia and Moldavia included people with the last name Palaiologos, ancestors of the Paleologu family.[124]
