Sack Of Amorium
The siege of Amorium by the Abbasid Caliphate in mid-August 838 was one of the major events in the long history of the Arab–Byzantine Wars. The Abbasid campaign was led personally by the Caliph al-Mu'tasim (), in retaliation to a virtually unopposed expedition launched by the Byzantine emperor Theophilos (r. 829–842) into the Caliphate's borderlands the previous year. Mu'tasim targeted Amorium, an Eastern Roman city in western Asia Minor, because it was the birthplace of the ruling Byzantine dynasty and, at the time, one of Byzantium's largest and most important cities. The caliph gathered an exceptionally large army, which he divided in two parts, which invaded from the northeast and the south. The northeastern army defeated the Byzantine forces under Theophilos at Anzen, allowing the Abbasids to penetrate deep into Byzantine Asia Minor and converge upon Ancyra, which they found abandoned. After sacking the city, they turned south to Amorium, where they arrived on 1 Augu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Al-Mu'tasim
Abū Isḥāq Muḥammad ibn Hārūn al-Rashīd (; October 796 – 5 January 842), better known by his laqab, regnal name al-Muʿtaṣim biʾllāh (, ), was the eighth Abbasid Caliphate, Abbasid caliph, ruling from 833 until his death in 842. When al-Ma'mun died unexpectedly on campaign in August 833, al-Mu'tasim was thus well placed to succeed him, with the support of the powerful chief , Ahmad ibn Abi Duwad, he continued to implement the rationalist Islamic doctrine of Mu'tazilism and implementing policy. 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 peoples, 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 under the Amorian dynasty, Byzantine ...

Abbasid Caliphate
The Abbasid Caliphate or Abbasid Empire (; ) was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. After overthrowing the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH), they ruled as caliphs based in modern-day Iraq, with Baghdad being their capital for most of their history. The Abbasid Revolution had its origins and first successes in the easterly region of Khurasan, far from the Levantine center of Umayyad influence. The Abbasid Caliphate first centered its government in Kufa, modern-day Iraq, but in 762 the caliph al-Mansur founded the city of Baghdad as the new capital. Baghdad became the center of science, culture, arts, and invention in what became known as the Golden Age of Islam. By housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi- ...

Theophilos (emperor)
Theophilos (, sometimes Latinised as Theophilus; 20 January 842) was 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. Theophilos was well-educated in the imperial household but upon his accession to the throne was met with the dual threat of the Abbasid Caliphate in Asia Minor and the Aghlabids in Sicily. He personally led the armies in his long war against both the Abbasid Caliphate and the Aghlabids in Sicily, beginning in 831. He won fleeting victories but the retaliation of Caliph al-Mu'tasim () was devastating, as was most humiliating in the Sack of Amorion in 838, the ancestral home of Theophilos' Amorian dynasty. Internal strife within the Caliphate allowed the Byzantines to recover. Theophilos engaged in many construction and renovation projects. One of his closest allies was the learned and cosmopolitan John the Grammarian, and they both improved relations with the Caliph ...

Presian I Of Bulgaria
Presian, sometimes enumerated as Presian I () was the khan of First Bulgarian Empire, Bulgaria in 836–852. He ruled during an extensive expansion in Macedonia (region), Macedonia. Origin The composite picture of the Byzantine sources indicates that Presian was the son of Zvinitsa (''Zbēnitzēs''), who was a son of Omurtag of Bulgaria, Omurtag. In several older studies Presian is identified with his short-lived predecessor Malamir of Bulgaria, Malamir and it is assumed that this single character survived until the 850s as the direct predecessor of Boris I. This is very unlikely, as Malamir is attested as having been succeeded by his nephew (the son of his brother Zvinitsa), while Boris I was preceded by his father Presian. Zlatarski resolved the problems in the fragmentary sources by determining that Malamir's unnamed nephew and successor was in fact Presian, and Boris I was the latter's son.

The tribe revolted against the Byzantine authorities of Constantinople in 837 and were supported by Bulgarian ruler Presian, who, together with his deputy ''Kavhan'' Isbul, crossed the lands of the Smolyani and conquered the territory as far south as Philippi, including most of Macedonia. Their name etymologically derives from the Proto-Slavic word *''smola'' ('resin'), with same derivation being ethnonym of the West Slavic tribe of Smeldingi and the East Slavic toponym of the city of Smolensk. The city of Smolyan in southern Bulgaria is named after this tribe.
