Title: Demetrios Palaiologos (son of Andronikos II)
Content:  Demetrios Angelos Doukas Palaiologos (Δημήτριος Ἄγγελος Δούκας Παλαιολόγος; ca. 1297 – after 1343) was a son of the Byzantine Emperor Andronikos II Palaiologos (reigned 1282–1328) and his second wife, Irene of Montferrat. Born ca. 1297, Demetrios was the youngest of Andronikos II's sons. In ca. 1304, he was sent to the court of the Serbian ruler Stephen Uroš II Milutin, intended to become his successor; his stay there was short, however, and he soon returned to Constantinople. In 1306 he was named to the highest court rank, that of Despot. In the Byzantine civil war of 1321–1328, Demetrios sided with his father against his nephew, Andronikos III Palaiologos. 
Title: Demetrios Palaiologos
Content:  Demetrios Palaiologos or Demetrius Palaeologus (Δημήτριος Παλαιολόγος; 1407–1470) was Despot of the Morea together with his brother Thomas from 1449 until the fall of the despotate in 1460. Demetrios and Thomas were sons of Byzantine Emperor Manuel II Palaiologos, and brothers of the final two emperors John VIII and Constantine XI. Demetrios had a complicated relationship with his brothers, who he frequently quarreled with, usually over the matter of Demetrios's wish to establish himself as the most senior of them and claim the imperial throne for himself. In 1437, Demetrios accompanied his older brother John VIII to the Council of Florence, the main objective of which was to unify the Roman Catholic and Eastern Orthodox churches so that Western

Content:  1327–1328, during the last stage of the civil war, he served as governor of Thessalonica. Eventually he was forced to flee to Serbia, while Andronikos III managed to take his wife and children captive, but Demetrios returned to Constantinople after Andronikos III's final victory. Demetrios was accused of conspiring against his nephew in 1336/37, but Andronikos III dropped the charges. Nothing more is known of him after 1343. Demetrios was also an accomplished theologian and miniature painter. The identity of his wife is not established, but she was possibly Theodora Komnene. By her he had a daughter, the future empress Irene, and at least one other, unnamed, child.
Title: Demetrios Palaiologos
Content:  Asen was appointed as governor of Corinth by Demetrios. Before his marriage to Theodora, Demetrios had been married either once or twice. His previous marriage(s) had not produced any children. His first wife was the daughter of Kantakouzenos Strabomytes, between 1430 and c. undefined 1435. His second wife, possibly the same person as the daughter of Kantakouzenos Strabomytes, is known only as the "basilissa Zoe" and died in March/April 1436. In 1452, during the preparation stages of the final Ottoman siege of Constantinople, Constantine XI sent an urgent message to the Morea, requesting that one of his brothers bring their forces to help him defend the city. To prevent aid 
Title: Demetrios Palaiologos
Content:  Demetrios (born in 1407), and Thomas, were kept in Constantinople as there was not sufficient land left to grant them. The younger children; Theodore, Andronikos, Constantine, Demetrios and Thomas were frequently described as having the distinction of Porphyrogennetos ("born in the purple"; born in the imperial palace during the reign of their father), a distinction that does not appear to have been shared by the emperor-to-be John. Relations between the Palaiologos brothers were not always good. Though the young John and Constantine appears to have got on well with each other, relations between Constantine and the younger Demetrios and Thomas were not as friendly. Demetrios was made the despot of the island of Lemnos in 1422 by Manuel; however, he was not

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. 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. 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.
Title: Succession to the Byzantine Empire
Content:  the Ottoman conquest mainly looked to the surviving members of the Palaiologos dynasty as prospective emperors, with it being suggested by some to crown Demetrios Palaiologos (1407–1470), Constantine XI's brother, who ruled in the Morea. Demetrios was reluctant and was captured by the Ottomans in 1460. In 1483, Constantine XI's nephew, Andreas Palaiologos (1453–1502), in exile in Italy, proclaimed himself as the rightful emperor. The last documented and verified male-line descendants of the Palaiologoi died out in the early 16th century but that did little to stop forgers, pretenders, impostors and eccentrics from claiming descent from the ancient emperors, not only the Palaiologoi but also earlier ruling dynasties of the 
Title: Theodore Palaiologos (stratiote)
Content:  Theodore Palaiologos was born in 1452, the son of Paulos Palaiologos. Paulos was probably from the Morea (the medieval name for the Peloponnese peninsula in southern Greece) and Theodore was likely born at Mystras, the peninsula's capital. They shared their last name with the Palaiologos dynasty, the final ruling dynasty of the Byzantine Empire, but are unlikely to have been related to the imperial family. The Palaiologos family had been extensive even before they became the empire's ruling dynasty, so it is plausible that Theodore and his family were distant cousins of the emperors. Theodore had three siblings; Georgios (Giorgio or Zorzi in Italian), Matthew (who would become the abbot of a monastery on Zakynthos) and a sister whose name remains unknown. In his youth, Theodore originally worked as a soubashi (debt-collector/police enforcer) in the Peloponnese on behalf of the Ottoman Empire, which conquered the Morea in 1460, before he, his father, and his brother Georgios, took up service with the Republic of Venice as stratioti (light-armed mercenary cavalrymen) in 1478. In due time, Paulos, Theodore and Georgios would all rise through the ranks to become capo dei stratioti ("head of the stratioti").
Title: Demetrios Palaiologos
Content:  Demetrios raised the possibility of a marriage alliance with Alfonso of Aragon and Naples, suggesting that his daughter Helena marry Alfonso's grandson. Despite his own views on the Council of Florence, Demetrios even sent his own envoy to Pope Nicholas V's successor, Pope Callixtus III, in 1455; Frankoulios Servopoulos, a known supporter of the Council of Florence. Servopoulos probably arrived in Rome at around the same time as Thomas's envoy, Argyropoulos, and the two envoys travelled through Europe, visiting the same courts, independently of each other. Thomas and Demetrios proved to be incapable of working together even with foreign diplomacy.
Title: Demetrios Palaiologos Kantakouzenos
Content:  Demetrios Palaiologos Kantakouzenos (Δημήτριος Παλαιολόγος Καντακουζηνός; ) was the mesazon (chief minister) of the Emperors John VIII Palaiologos and his brother, Constantine XI. His colleague in the office as mesazon was Loukas Notaras. Demetrios first appears in history as one of the courtiers who advised John VIII to support the Ottoman prince Mustafa in his bid to seize control of the Ottoman Empire on the death of his brother Mehmet I in 1421. When Mehmet's son Murat emerged as the victor, he was selected as one of the envoys (the other two being Matthew Laskaris and Angelos Philomattes) to meet with Murat. The Sultan showed his annoyance that
