Bihar was a Khagan of the Khazars during the 730s. [1] Bihar was the father of Tzitzak, the Khazar princess who married the son of Byzantine Emperor Leo III who later ruled as Constantine V. Bihar was thus the grandfather of Emperor Leo IV the Khazar. He is called Viharos in Armenian sources.
The Khazars were a nomadic Turkic people that, in the late 6th-century CE, established a major commercial empire covering the southeastern section of modern European Russia, southern Ukraine, Crimea, and Kazakhstan. They created what for its duration was the most powerful polity to emerge from the break-up of the Western Turkic Khaganate. Astride a major artery of commerce between Eastern Europe and Southwestern Asia, Khazaria became one of the foremost trading empires of the early medieval world, commanding the western marches of the Silk Road and playing a key commercial role as a crossroad between China, the Middle East and Kievan Rus'. For some three centuries the Khazars dominated the vast area extending from the Volga-Don steppes to the eastern Crimea and the northern Caucasus.
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.

Sviatoslav or Svyatoslav I Igorevich was Prince of Kiev from 945 until his death in 972. He is known for his persistent campaigns in the east and south, which precipitated the collapse of two great powers in Eastern Europe, Khazaria and the First Bulgarian Empire. He conquered numerous East Slavic tribes, defeated the Alans and attacked the Volga Bulgars, and at times was allied with the Pechenegs and Magyars (Hungarians).
Leo IV the Khazar was Byzantine emperor from 775 to 780 AD. He was born to Emperor Constantine V and Empress Tzitzak in 750. He was elevated to co-emperor in the next year, in 751, and married to Irene of Athens in 768. When Constantine V died in September 775, while campaigning against the Bulgarians, Leo IV became senior emperor. In 778 Leo raided Abbasid Syria, decisively defeating the Abbasid army outside of Germanikeia. Leo died on 8 September 780, of tuberculosis. He was succeeded by his underage son Constantine VI, with Irene serving as regent.
Michael III, also known as Michael the Drunkard, was Byzantine emperor from 842 to 867. Michael III was the third and traditionally last member of the Amorian dynasty. He was given the disparaging epithet the Drunkard by the hostile historians of the succeeding Macedonian dynasty, but modern historical research has rehabilitated his reputation to some extent, demonstrating the vital role his reign played in the resurgence of Byzantine power in the 9th century. He was also the youngest person to bear the imperial title, as well as the youngest to succeed as senior emperor.
Theophanes the Confessor was a member of the Byzantine aristocracy who became a monk and chronicler. He served in the court of Emperor Leo IV the Khazar before taking up the religious life. Theophanes attended the Second Council of Nicaea in 787 and resisted the iconoclasm of Leo V the Armenian, for which he was imprisoned. He died shortly after his release.
The Kabars, also known as Qavars (Qabars) or Khavars were Khazar rebels who joined the Magyar confederation possibly in the 9th century as well as the Rus' Khaganate.

The Byzantine Empire was ruled by the Isaurian dynasty from 717 to 802. The Isaurian emperors were successful in defending and consolidating the empire against the caliphates after the onslaught of the early Muslim conquests, but were less successful in Europe, where they suffered setbacks against the Bulgars, had to give up the Exarchate of Ravenna, and lost influence over Italy and the papacy to the growing power of the Franks.
Eudokia was the third empress consort of Constantine V of the Byzantine Empire. According to the chronicle of Theophanes the Confessor, Eudokia was a sister-in-law of Michael Melissenos, strategos of the Anatolikon Theme. Her sister and brother-in-law were parents to Theodotus I of Constantinople.
Maria was the second empress consort of Constantine V of the Byzantine Empire.
The siege of Nicaea of 727 was an unsuccessful attempt by the Umayyad Caliphate to capture the Byzantine city of Nicaea, the capital of the Opsician Theme. Ever since its failure to capture the Byzantine Empire's capital, Constantinople, in 717–718, the Caliphate had launched a series of raids into Byzantine Asia Minor. In 727, the Arab army, led by one of the Caliph's sons, penetrated deep into Asia Minor, sacked two Byzantine fortresses and in late July arrived before Nicaea. Despite constant attacks for 40 days, the city held firm and the Arabs withdrew and returned to the Caliphate. The successful repulsion of the attack was a major boost for Byzantine emperor Leo III the Isaurian's recently initiated campaign to abolish the veneration of icons in the Empire; Leo claimed it as evidence of divine favour for his policy. The siege of Nicaea marks also the high point of the Umayyad raids, as new threats and defeats on their far-flung frontiers decreased Umayyad strength elsewhere, while Byzantine power strengthened afterwards.
The Theme of Cherson, originally and formally called the Klimata, was a Byzantine theme located in the southern Crimea, headquartered at Cherson.
Tiberius, sometimes enumerated as Tiberius IV, was the son of Emperor Justinian II and Theodora of Khazaria. He served as co-emperor of the Byzantine Empire with his father Justinian II, from 706 to 711. Both were killed in 711, when Bardanes led a rebellion which marched on Constantinople. After Tiberius' death, two different individuals impersonated him, with one, named Bashir, going on to be hosted by Hisham ibn Abd al-Malik, the Umayyad caliph, before his lie was discovered and he was crucified.
