Constantine Opos (megas Doux)
Constantine Opos ( el, ) was a notable Byzantine general and aristocrat in the first half of the reign of Emperor Alexios I Komnenos (r. 1081–1118). He participated in the wars against the Normans and the Seljuk Turks, eventually reaching the rank of '' megas doux'' (commander-in-chief of the Byzantine navy). Biography Constantine Opos first appears in the ''Alexiad'' in 1081, during Alexios's campaign against the Normans of Robert Guiscard, leading the '' tagma'' of the ''Exkoubitoi''. The campaign ended in the Byzantine defeat at the Battle of Dyrrhachium on 18 October 1081, which effectively shattered the last remains of the old-established regiments of the middle Byzantine army. The ''Exkoubitoi'' are never heard from again; their remnants were probably disbanded, marking the end of this historic unit, which had been founded as an elite imperial bodyguard by Emperor Leo I the Thracian (r. 457–474). In 1090, Opos was subordinate to the admiral Constantine Dalassenos durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byzantine 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 ...

Smyrna
Smyrna ( ; grc, Σμύρνη, Smýrnē, or , ) was a Greek city located at a strategic point on the Aegean coast of Anatolia. Due to its advantageous port conditions, its ease of defence, and its good inland connections, Smyrna rose to prominence. The name of the city since about 1930 is İzmir. Two sites of the ancient city are today within Izmir's boundaries. The first site, probably founded by indigenous peoples, rose to prominence during the Archaic Period as one of the principal ancient Greek settlements in western Anatolia. The second, whose foundation is associated with Alexander the Great, reached metropolitan proportions during the period of the Roman Empire. Most of the present-day remains of the ancient city date from the Roman era, the majority from after a second-century AD earthquake. In practical terms, a distinction is often made between these. ''Old Smyrna'' was the initial settlement founded around the 11th century BC, first as an Aeolian settlement, and l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

11th-century Byzantine People
The 11th century is the period from 1001 ( MI) through 1100 ( MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynasty court created strife amongst th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bosporus
The Bosporus Strait (; grc, Βόσπορος ; tr, İstanbul Boğazı 'Istanbul strait', colloquially ''Boğaz'') or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul in northwestern Turkey. It forms part of the continental boundary between Asia and Europe, and divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation. Most of the shores of the Bosporus Strait, except for the area to the north, are heavily settled, with the city of Istanbul's metropolitan population of 17 million inhabitants extending inland from both banks. The Bosporus Strait and the Dardanelles Strait at the opposite end of the Sea of Marmara are together known as the Turkish Straits. Sections of the shore of the Bosporus in Istanbul have been reinforced with concrete or rubble and those sections of the Strait prone to deposition are periodically dredged. Name The name of th ...

First Crusade
The First Crusade (1096–1099) was the first of a series of religious wars, or Crusades, initiated, supported and at times directed by the Latin Church in the medieval period. The objective was the recovery of the Holy Land from Islamic rule. While Jerusalem had been under Muslim rule for hundreds of years, by the 11th century the Seljuk takeover of the region threatened local Christian populations, pilgrimages from the West, and the Byzantine Empire itself. The earliest initiative for the First Crusade began in 1095 when Byzantine emperor Alexios I Komnenos requested military support from the Council of Piacenza in the empire's conflict with the Seljuk-led Turks. This was followed later in the year by the Council of Clermont, during which Pope Urban II supported the Byzantine request for military assistance and also urged faithful Christians to undertake an armed pilgrimage to Jerusalem. This call was met with an enthusiastic popular response across all social classes in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protoproedros
''Proedros'' ( el, πρόεδρος, "president") was a senior Byzantine court and ecclesiastic title in the 10th to mid-12th centuries. The female form of the title is ''proedrissa'' (προέδρισσα). Court dignity The title was created in the 960s by Nikephoros II Phokas and was first awarded to Basil Lekapenos, the eunuch '' parakoimōmenos''. It was placed very high in the court hierarchy, coming immediately below the position of the '' zostē patrikia'' and before the ''magistros'', meaning that it was the most senior non-imperial title open to males. The title apparently continued to be restricted to eunuchs until the mid-11th century, when it was opened up to the wider aristocracy and extensively awarded. The holder of this dignity was also the president of the Senate (), and the term ''proedros'' was often used to denote precedence in other offices, e.g. ''proedros'' of the ''notarioi'' for the '' prōtonotarios''. The title was widely awarded in the 11th century, aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leo Of Chalcedon
Leo of Chalcedon was an 11th-century Eastern Orthodox bishop of Chalcedon who opposed the appropriation of church treasures by Byzantine emperor Alexios I Komnenos between 1081 and 1091. Alexios I was in a desperate situation upon ascending the throne in 1081. With the Byzantine-Norman Wars draining what little money remained in the imperial treasury, and Robert Guiscard marching across the Balkans, Alexios was forced to assemble a synod of Greek ecclesiastics who authorised him to employ the wealth gathered as offerings in the churches for public service. This act was violently opposed by many of the clergy, with Leo, Bishop of Chalcedon being among the most prominent. Leo declared that the government had committed sacrilege in melting down sacred objects which were entitled to the adoration of Christians. Leo's opposition forced the emperor to back down temporarily in 1082. The resumption of confiscations soon after and the lack of resistance by Patriarch Nicholas III and the ...

Apollonia Ad Rhyndacum
Apollonia or Apollonia-on-the-Rhyndacus ( grc, Ἀπολλωνία ἐπὶ Ῥυνδακῷ, ''Apollōnía épì Ryndakō''; la, Apollonia ad Rhyndacum) was an ancient town opposite the delta of the Rhyndacus river in northwestern Anatolia and corresponds today to the town of Gölyazı. Location Nine cities known as Apollonia were build during antiquity in Anatolia. Strabo placed Apollonia-on-the-Rhyndacus in Mysia, causing some to misidentify Uluabat as Apollonia on the western shore of Lake Uluabat. However, the site is actually the promontory tombolo on the northeastern shore, near modern Gölyazı. Lake Uluabat extends from east to west and is studded with several islands and peninsulas, on one of which the city of Apollonia was built. The name of “Apollonia ad Rhyndacum” was likely chosen in order to differentiate from the other cities in the antiquity with reference to the stream “Rhyndacus (Adranos)” located close to the city and stemming from Aizanoi (Çavda ...
