Metropolitan Bishop
In Christian churches with episcopal polity, the rank of metropolitan bishop, or simply metropolitan (alternative obsolete form: metropolite), pertains to the diocesan bishop or archbishop of a metropolis. Originally, the term referred to the bishop of the chief city of a historical Roman province, whose authority in relation to the other bishops of the province was recognized by the First Council of Nicaea (AD 325). The bishop of the provincial capital, the metropolitan, enjoyed certain rights over other bishops in the province, later called " suffragan bishops". The term ''metropolitan'' may refer in a similar sense to the bishop of the chief episcopal see (the "metropolitan see") of an ecclesiastical province. The head of such a metropolitan see has the rank of archbishop and is therefore called the metropolitan archbishop of the ecclesiastical province. Metropolitan (arch)bishops preside over synods of the bishops of their ecclesiastical province, and canon law and traditio ...

Forty Martyrs Of Sebaste
The Forty Martyrs of Sebaste or the Holy Forty (Ancient/Katharevousa Greek ''Ἅγιοι Τεσσεράκοντα''; Demotic: ''Άγιοι Σαράντα'') were a group of Roman soldiers in the Legio XII ''Fulminata'' (Armed with Lightning) whose martyrdom in 320 for the Christian faith is recounted in traditional martyrologies. They were killed near the city of Sebaste, in Lesser Armenia (present-day Sivas in Turkey), victims of the persecutions of Licinius, who after 316, persecuted the Christians of the East. The earliest account of their existence and martyrdom is given by Bishop Basil of Caesarea (370–379) in a homily he delivered on their feast day. The Feast of the Forty Martyrs is thus older than Basil himself, who eulogised them only fifty or sixty years after their deaths. Martyrdom According to Basil, forty soldiers who had openly confessed themselves Christians were condemned by the prefect to be exposed naked upon a frozen pond near Sebaste on a bitterly cold ...

Theophilos (emperor)
Theophilos ( gr, Θεόφιλος; sometimes Latinized or Anglicized as Theophilus or Theophilo; c. 812 20 January 842) was the Byzantine Emperor from 829 until his death in 842. He was the second emperor of the Amorian dynasty and the last emperor to support iconoclasm.Timothy E. Gregory (2010). ''A History of Byzantium''. Blackwell Publishing Ltd. p. 227. Theophilos personally led the armies in his long war against the Arabs, beginning in 831. Life Early Theophilos was the son of the Byzantine Phrygian Greek Emperor Michael II and his wife Thekla, and the godson of Emperor Leo V the Armenian. Michael II crowned Theophilos co-emperor in 821. The date is almost universally given as 12 May 821 (Whitsunday), although this is not really corroborated by any source (another possible date is 24 March, Easter). Unlike his father, Theophilos received an extensive education from John Hylilas, the grammarian, and was a great admirer of music and art. On 2 October 829, Theophilos suc ...

Byzantine Emperor
This is a list of the Byzantine emperors from the foundation of Constantinople in 330 AD, which marks the conventional start of the Eastern Roman Empire, to its fall to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors (''symbasileis'') who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title. The following list starts with Constantine the Great, the first Christian emperor, who rebuilt the city of Byzantium as an imperial capital, Constantinople, and who was regarded by the later emperors as the model ruler. It was under Constantine that the major characteristics of what is considered the Byzantine state emerged: a Roman polity centered at Constantinople and culturally dominated by the Greek East, with Christianity as the state religion. The Byzantine Empire was the direct le ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Al-Mutasim
Abū Isḥāq Muḥammad ibn Hārūn al-Rashīd ( ar, أبو إسحاق محمد بن هارون الرشيد; October 796 – 5 January 842), better known by his regnal name al-Muʿtaṣim biʾllāh (, ), was the eighth Abbasid caliph, ruling from 833 until his death in 842. A younger son of Caliph Harun al-Rashid (r. 786–809), he rose to prominence through his formation of a private army composed predominantly of Turkic slave-soldiers (, sing. ). This proved useful to his half-brother, Caliph al-Ma'mun, who employed al-Mu'tasim and his Turkish guard to counterbalance other powerful interest groups in the state, as well as employing them in campaigns against rebels and the Byzantine Empire. When al-Ma'mun died unexpectedly on campaign in August 833, al-Mu'tasim was thus well placed to succeed him, overriding the claims of al-Ma'mun's son al-Abbas. Al-Mu'tasim continued many of his brother's policies, such as the partnership with the Tahirids, who governed Khurasan and Baghd ...

Theophanes Continuatus
''Theophanes Continuatus'' ( el, συνεχισταί Θεοφάνους) or ''Scriptores post Theophanem'' (, "those after Theophanes") is the Latin name commonly applied to a collection of historical writings preserved in the 11th-century Vat. gr. 167 manuscript.Kazhdan (1991), p. 2061 Its name derives from its role as the continuation, covering the years 813–961, of the chronicle of Theophanes the Confessor, which reaches from 285 to 813. The manuscript consists of four distinct works, in style and form very unlike the annalistic approach of Theophanes.Kazhdan (1991), pp. 2061–2062 The first work, of four books consists of a series of biographies of the emperors reigning from 813 to 867 (from Leo the Armenian to Michael III). As they were commissioned by Emperor Constantine VII (r. 913–959), they reflect the point of view of the reigning Macedonian dynasty. The unknown author probably used the same sources as Genesios. The second work is known as the ''Vita Basilii'' (La ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Joseph Genesius
Genesius ( el, Γενέσιος, ''Genesios'') is the conventional name given to the anonymous Byzantine author of Armenian origin of the tenth century chronicle, ''On the reign of the emperors''. His first name is sometimes given as Joseph, combining him with a "Joseph Genesius" quoted in the preamble to John Skylitzes. Traditionally, he has been regarded as the son or grandson of Constantine Maniakes. Composed at the court of Constantine VII, the chronicle opens in 814, covers the Second Iconoclast period and ends in 886. It presents the events largely from the view of the Macedonian dynasty, though with a skew less marked than the authors of Theophanes Continuatus, a collection of mostly anonymous chronicles meant to continue the work of Theophanes the Confessor. The chronicle describes the reigns of the four emperors from Leo V down to Michael III in detail; and more briefly that of Basil I. It uses Constantine VII's ''Life of Basil'' as a source, though it appears to have bee ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Baghdad
Baghdad (; ar, بَغْدَاد , ) is the capital of Iraq and the second-largest city in the Arab world after Cairo. It is located on the Tigris near the ruins of the ancient city of Babylon and the Sassanid Persian capital of Ctesiphon. In 762 CE, Baghdad was chosen as the capital of the Abbasid Caliphate, and became its most notable major development project. Within a short time, the city evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many c ...
