Doukas
From Wikipedia, the free encyclopedia
Doukas or Ducas (Greek: Δούκας; fem. Doukaina or Ducaena, Δούκαινα; pl. Doukai or Ducae, Δούκαι) is the name of a Byzantine family allegedly descended from a cousin of the Roman Emperor Constantine I who had migrated to Constantinople in the 4th century. The family or families using this surname supplied several rulers to the Byzantine Empire.
The original family first came into prominence during the 9th century, but was ruined when Constantine Doukas, a son of the general Andronikos Doukas, lost his life in his effort to obtain the imperial crown in 913, against the regent government of Constantine VII the Porphyrogennetos.
Towards the end of the 10th century there appeared another family of Doukas, which was perhaps connected with the earlier family through the female line and was destined to attain to greater fortune. A member of this family became emperor as Constantine X in 1059, and Constantine's son Michael VII ruled, nominally in conjunction with his younger brothers, Andronikos and Konstantios, from 1071 to 1078. Michael left a son, Constantine, who reigned nominally alongside his father and then Alexios I Komnenos. The latter married Irene Doukaina, the great-niece of Constantine X and united the Doukai and Komnenoi.
The family was also allied by marriage with other great Byzantine houses, and after losing the imperial dignity its members continued to take an active part in public affairs. In 1204 Alexius Doukas, called Mourtzouphlos, deposed the emperor Isaac II Angelos and his son Alexios IV Angelos, and unsuccessfully tried to defend Constantinople against the attacks of the forces of the Fourth Crusade. Later John III Doukas Vatatzes expanded the Empire of Nicaea into Europe and launched it on the road to recovering Constantinople. Nearly a century later one Michael Doukas took a leading part in the civil war between the emperors John V Palaiologos and John VI Kantakouzenos, and Michael's grandson was the historian Doukas (see below).
Through the dynastic marriages of the Doukai with other members of the Byzantine nobility, and especially with the Komnenoi, the name Doukas was adopted into several other families, most notably by the relatively low-born Angeloi, Constantine Angelos having married Theodora, the daughter of Alexios I Komnenos and Irene Doukaina. One of Constantine's sons became known as John Doukas and his descendants reigned over Epirus and Thessalonica calling themselves mostly Komnenos Doukas and only rarely Angelos. A branch of this family called itself simply Doukas and reigned in Thessaly.
Doukas or Ducas (fl. 15th century), Byzantine historian, flourished under Constantine XI Dragases, the last emperor of the East, about 1450. The dates of his birth and death are unknown. He was the grandson of Michael Doukas (see above). After the fall of Constantinople, he was employed in various diplomatic missions by Dorino and Domenico Gattilusio, princes of Lesbos, where he had taken refuge. He was successful in securing a semi-independence for Lesbos until 1462, when it was taken and annexed to the Ottoman Empire by Sultan Mehmed II of the Ottoman Dynasty. It is known that Ducas survived this event, but there is no record of his subsequent life. He was the author of a history of the period 1341-1462; his work thus continues that of Nikephoros Gregoras and John Kantakouzenos, and supplements George Sphrantzes and Laonikos Chalkokondyles. There is a preliminary chapter of chronology from Adam to John V Palaiologos. Although unrefined in style, the history of Doukas is both judicious and trustworthy, and it is the most valuable source for the closing years of the Byzabtine empire. The account of the Fall of Constantinople is of special importance. Doukas was a strong supporter of the union of the Greek and Latin churches, and is very bitter against those who rejected even the idea of appealing to the West for assistance against the Ottomans.
The history, preserved (without a title) in a single manuscript conserved in Paris, was first edited by I. Bullialdus (Bulliaud) (Paris, 1649); later editions are in the Bonn Corpus scriptorum Hist. Byz., by I. Bekker (1834) and Migne, Patrologia Graeca, clvii. The Bonn edition contains a 15th century Italian translation by an unknown author, found by Leopold Ranke in one of the libraries of Venice, and sent by him to Bekker.
