Leo III the Isaurian, also known as the Syrian or as the Assyrian, was the first Byzantine emperor of the Isaurian dynasty from 717 until his death in 741. He put an end to the Twenty Years' Anarchy, a period of great instability in the Byzantine Empire between 695 and 717, marked by the rapid succession of several emperors to the throne, along with ending the continual defeats and territorial losses the Byzantines had suffered during the 7th century. He also successfully defended the Empire against the invading Umayyads and forbade the veneration of icons.
Year 718 (DCCXVIII) was a common year starting on Saturday of the Julian calendar, the 718th year of the Common Era (CE) and Anno Domini (AD) designations, the 718th year of the 1st millennium, the 18th year of the 8th century, and the 9th year of the 710s decade. The denomination 718 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Theophilos 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. Theophilos personally led the armies in his long war against the Arabs, beginning in 831.
The Arab–Byzantine wars were a series of wars from the 7th to 11th centuries between multiple Arab dynasties and the Byzantine Empire. The Muslim Arab Caliphates conquered large parts of the Christian Byzantine empire and unsuccessfully attacked the Byzantine capital of Constantinople. The frontier between the warring states remained almost static for three centuries of frequent warfare, before the Byzantines were able to recapture some of the lost territory.
The second Arab siege of Constantinople was a combined land and sea offensive in 717–718 by the Muslim Arabs of the Umayyad Caliphate against the capital city of the Byzantine Empire, Constantinople. The campaign marked the culmination of twenty years of attacks and progressive Arab occupation of the Byzantine borderlands, while Byzantine strength was sapped by prolonged internal turmoil. In 716, after years of preparations, the Arabs, led by Maslama ibn Abd al-Malik, invaded Byzantine Asia Minor. The Arabs initially hoped to exploit Byzantine civil strife and made common cause with the general Leo III the Isaurian, who had risen up against Emperor Theodosius III. Leo, however, deceived them and secured the Byzantine throne for himself.
Euphemius or Euphemios was a Byzantine commander in Sicily, who rebelled against the imperial governor in 826 AD, and invited the Aghlabids to aid him, thus beginning the Muslim conquest of Sicily.
The first Arab siege of Constantinople in 674–678 was a major conflict of the Arab–Byzantine wars, and the first culmination of the Umayyad Caliphate's expansionist strategy towards the Byzantine Empire, led by Caliph Mu'awiya I. Mu'awiya, who had emerged in 661 as the ruler of the Muslim Arab empire following a civil war, renewed aggressive warfare against Byzantium after a lapse of some years and hoped to deliver a lethal blow by capturing the Byzantine capital of Constantinople.
Leo of Tripoli, known in Arabic as Rashīq al-Wardāmī, and Ghulām Zurāfa, was a Greek renegade and fleet commander for the Abbasid Caliphate in the early tenth century. He is most notable for his sack of Thessalonica, the Byzantine Empire's second city, in 904.
The Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Muslim rule until conquered in turn by the Normans in the 11th century.
Niketas Oryphas or Oöryphas was a distinguished Byzantine official, patrikios, and admiral under the Byzantine emperors Michael III and Basil I the Macedonian, who achieved several naval victories against the Cretan Saracen raiders.
The Battle of Mauropotamos was fought in 844, between the armies of the Byzantine Empire and the Abbasid Caliphate, at Mauropotamos. After a failed Byzantine attempt to recover the Emirate of Crete in the previous year, the Abbasids launched a raid into Asia Minor. The Byzantine regent, Theoktistos, headed the army that went to meet the invasion but was heavily defeated, and many of his officers defected to the Arabs. Internal unrest prevented the Abbasids from exploiting their victory, however. A truce and a prisoner exchange were consequently agreed in 845, followed by a six-year cessation of hostilities, as both powers focused their attention elsewhere.
The Emirate of Crete was an Islamic state that existed on the Mediterranean island of Crete from the late 820s to the reconquest of the island by the Byzantine Empire in 961. Although the emirate recognized the suzerainty of the Abbasid Caliphate and maintained close ties with Tulunid Egypt, it was de facto independent.
The Karabisianoi, sometimes anglicized as the Carabisians, were the main forces of the Byzantine navy from the mid-seventh until the early eighth centuries. The name derives from a term for ships, and means "people of the ships". The Karabisianoi were the first new and permanent naval establishment of the Byzantine Empire, formed to confront the early Muslim conquests at sea. They were disbanded and replaced with a series of maritime themes sometime in 718–730.
The Sack of Thessalonica refers to the capture, and subsequent sack, of the Byzantine city of Thessalonica by the Abbasid Caliphate in the year 904, led by Leo of Tripoli, a privateer and Muslim convert.
The Cibyrrhaeot Theme, more properly the Theme of the Cibyrrhaeots, was a Byzantine theme encompassing the southern coast of Asia Minor from the early 8th to the late 12th centuries. As the Byzantine Empire's first and most important naval theme, it served chiefly to provide ships and troops for the Byzantine navy.
The siege of Syracuse from 877 to 878 led to the fall of the city of Syracuse, the Byzantine capital of Sicily, to the Aghlabids. The siege lasted from August 877 to 21 May 878 when the city, effectively left without assistance by the central Byzantine government, was taken by the Aghlabid forces.
The Theme of Cephallenia or Cephalonia was a Byzantine theme located in western Greece, comprising the Ionian Islands, and extant from the 8th century until partially conquered by the Kingdom of Sicily in 1185.
The Battle of Marash was fought in 953 near Marash between the forces of the Byzantine Empire under the Domestic of the Schools Bardas Phokas the Elder, and of the Hamdanid Emir of Aleppo, Sayf al-Dawla, the Byzantines' most intrepid enemy during the mid-10th century. Despite being outnumbered, the Arabs defeated the Byzantines who broke and fled. Bardas Phokas himself barely escaped through the intervention of his attendants, and suffered a serious wound on his face, while his youngest son and governor of Seleucia, Constantine Phokas, was captured and held a prisoner in Aleppo until his death of an illness some time later. This debacle, coupled with defeats in 954 and again in 955, led to Bardas Phokas' dismissal as Domestic of the Schools, and his replacement by his eldest son, Nikephoros Phokas.
The Battle of Kardia was a naval battle fought in c. 872/3 between the fleets of the Byzantine Empire and the Cretan Saracens off Kardia, in the Gulf of Saros. The battle was a major Byzantine victory.
The siege of Melite was the capture of the Byzantine city of Melite by an invading Aghlabid army in 870 AD. The siege was initially led by Halaf al-Hādim, a renowned engineer, but he was killed and replaced by Sawāda Ibn Muḥammad. The city withstood the siege for some weeks or months, but it ultimately fell to the invaders, and its inhabitants were massacred and the city was sacked.
