Niketas Triphyllios
Niketas Triphyllios ( el, Νικήτας Τριφύλλιος, died 30 April 803) was one of the highest officials of the Roman Empire during the reign of empress Irene of Athens (797–802), holding the position of Domestic of the Schools. Niketas first appears in Irene's unique triumphal procession on Easter Monday, 1 April 799. At the time, he was already Domestic of the Schools (commander of the elite '' Scholai'' regiment) and holder of the supreme dignity of ''patrikios''. Niketas was one of the four ''patrikioi'' (along with Bardanes Tourkos, Constantine Boilas, and Niketas' brother Sisinnios) leading the four white horses which drew the imperial carriage, a role that marks him out as one of the most prominent of Irene's supporters among the high dignitaries of the state.Guilland (1967), p. 436 A few weeks later, in May, Irene's health worsened considerably and the issue of her succession became opened. At this point Niketas (and possibly his brother too) allied himself wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Roman Empire
The Byzantine Empire, also referred to as the Eastern Roman Empire or Byzantium, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in Europe. The terms "Byzantine Empire" and "Eastern Roman Empire" were coined after the end of the realm; its citizens continued to refer to their empire as the Roman Empire, and to themselves as Romans—a term which Greeks continued to use for themselves into Ottoman times. Although the Roman state continued and its traditions were maintained, modern historians prefer to differentiate the Byzantine Empire from Ancient Rome a ...

Byzantine Generals
A Byzantine fault (also Byzantine generals problem, interactive consistency, source congruency, error avalanche, Byzantine agreement problem, and Byzantine failure) is a condition of a computer system, particularly distributed computing systems, where components may fail and there is imperfect information on whether a component has failed. The term takes its name from an allegory, the "Byzantine generals problem", developed to describe a situation in which, in order to avoid catastrophic failure of the system, the system's actors must agree on a concerted strategy, but some of these actors are unreliable. In a Byzantine fault, a component such as a server can inconsistently appear both failed and functioning to failure-detection systems, presenting different symptoms to different observers. It is difficult for the other components to declare it failed and shut it out of the network, because they need to first reach a consensus regarding which component has failed in the first pla ...

9th-century Byzantine People
The 9th century was a period from 801 ( DCCCI) through 900 ( CM) in accordance with the Julian calendar. The Carolingian Renaissance and the Viking raids occurred within this period. In the Middle East, the House of Wisdom was founded in Abbasid Baghdad, attracting many scholars to the city. The field of algebra was founded by the Muslim polymath al-Khwarizmi. The most famous Islamic Scholar Ahmad ibn Hanbal was tortured and imprisoned by Abbasid official Ahmad ibn Abi Du'ad during the reign of Abbasid caliph al-Mu'tasim and caliph al-Wathiq. In Southeast Asia, the height of the Mataram Kingdom happened in this century, while Burma would see the establishment of the major kingdom of Pagan. Tang China started the century with the effective rule under Emperor Xianzong and ended the century with the Huang Chao rebellions. While the Maya experienced widespread political collapse in the central Maya region, resulting in internecine warfare, the abandonment of cities, and a northw ...

8th-century Byzantine People
The 8th century is the period from 701 ( DCCI) through 800 ( DCCC) in accordance with the Julian Calendar. The coast of North Africa and the Iberian Peninsula quickly came under Islamic Arab domination. The westward expansion of the Umayyad Empire was famously halted at the siege of Constantinople by the Byzantine Empire and the Battle of Tours by the Franks. The tide of Arab conquest came to an end in the middle of the 8th century.Roberts, J., ''History of the World'', Penguin, 1994. In Europe, late in the century, the Vikings, seafaring peoples from Scandinavia, begin raiding the coasts of Europe and the Mediterranean, and go on to found several important kingdoms. In Asia, the Pala Empire is founded in Bengal. The Tang dynasty reaches its pinnacle under Chinese Emperor Xuanzong. The Nara period begins in Japan.

Nikephoros I
Nikephoros I or Nicephorus I ( gr, Νικηφόρος; 750 – 26 July 811) was Byzantine emperor from 802 to 811. Having served Empress Irene as '' genikos logothetēs'', he subsequently ousted her from power and took the throne himself. In reference to his career before becoming emperor, he is sometimes surnamed "the Logothete" (ὁ Λογοθέτης) and "Genikos" or "Genicus" (ὁ Γενικός). Nikephoros pursued wars against the Arabs and Bulgarians, with mixed results; while invading Bulgaria he was defeated and killed at the Battle of Pliska. Background Sources outside the Byzantine context, including Michael the Syrian, al-Tabari, and Mas'udi, preserve the tradition that Nikephoros was of Ghassanid Arab origin. al-Tabari claims that he derived this information from Byzantine sources, but no surviving Byzantine chronicle makes explicit mention of the emperor's ethnic background. The modern scholar Paul Julius Alexander suggests that al-Tabari did transmit informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Logothete
The ( gr, λογοθέτης τοῦ γενικοῦ, often called or simply (, 'the general ogothete), and usually rendered in English as the General Logothete, was in charge of the 'general financial ministry', the of the middle Byzantine Empire.. History and functions The was responsible for general taxation and revenue, and also served as a court for financial cases. As such, it broadly fulfilled the tasks of the earlier , although it was mostly derived from the "general department" of the praetorian prefecture. The first attested , the monk Theodotos, is mentioned in 692, but the post may have been instituted as early as 626. The bureau of the and its logothete remained one of the chief ministries for the entire middle Byzantine period (7th–12th centuries). During the Komnenian period, its importance declined, but recovered under the Angeloi. Following the sack of Constantinople in 1204 and the dissolution of the Byzantine Empire, the office of the was retained as ...

Thrace (theme)
The Theme of Thrace ( el, ) was a province (''thema'' or theme) of the Byzantine Empire located in the south-eastern Balkans, comprising varying parts of the eponymous geographic region during its history. History Traditionally, it has been held that the theme (at the time primarily a military command) was constituted in c. 680, as a response to the Bulgar threat... This is based on the mention of a certain ''patrikios'' Theodore, Count of the ''Opsikion'' and ''hypostrategos'' of Thrace, in 680/681. However, it is unclear whether this implies the existence of Thrace as a separate command, with Theodore holding a dual post, or whether Thrace was administratively united to the ''Opsikion''. In fact, separate ''strategoi'' of Thrace are not clearly attested in literary sources until 742, while seals of ''strategoi'' are also extant only from the eighth century on. Initially, Adrianople was probably the theme's capital. Under Empress Irene of Athens, in the late eighth century, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cappadocia
Cappadocia or Capadocia (; tr, Kapadokya), is a historical region in Central Anatolia, Turkey. It largely is in the provinces Nevşehir, Kayseri, Aksaray, Kırşehir, Sivas and Niğde. According to Herodotus, in the time of the Ionian Revolt (499 BC), the Cappadocians were reported as occupying a region from Mount Taurus to the vicinity of the Euxine (Black Sea). Cappadocia, in this sense, was bounded in the south by the chain of the Taurus Mountains that separate it from Cilicia, to the east by the upper Euphrates, to the north by Pontus, and to the west by Lycaonia and eastern Galatia.
