Theodosius III was Byzantine emperor from c. May 715 to 25 March 717. Before rising to power and seizing the throne of the Byzantine Empire, he was a tax collector in Adramyttium. In 715, the Byzantine navy and the troops of the Opsician Theme, one of the Byzantine provinces, revolted against Emperor Anastasius II, acclaiming the reluctant Theodosius as emperor. Theodosius led his troops to Chrysopolis and then Constantinople, the capital, seizing the city in November 715. Anastasius did not surrender until several months later, accepting exile in a monastery in return for safety. Many themes viewed Theodosius to be a puppet of the troops of the Opsician Theme, and his legitimacy was denied by the Anatolics and the Armeniacs under their respective strategoi (generals) Leo the Isaurian and Artabasdos.
Constans II, nicknamed "the Bearded", was the Byzantine emperor from 641 to 668. Constans was the last attested emperor to serve as consul, in 642, although the office continued to exist until the reign of Leo VI the Wise. His religious policy saw him steering a middle line in disputes between the Orthodoxy and Monothelitism by refusing to persecute either and prohibited discussion of the natures of Jesus Christ under the Type of Constans in 648. His reign coincided with Muslim invasions under, Umar, Uthman, and Mu'awiya I in the late 640s to 660s. Constans was the first emperor to visit Rome since the fall of the Western Roman Empire in 476, and the last one to visit Rome while it was still held by the Empire.
Tiberius III, born Apsimar, was Byzantine emperor from 698 to 705. Little is known about his early life, other than that he was a droungarios, a mid-level commander, who served in the Cibyrrhaeot Theme. In 696, Tiberius was part of an army sent by Byzantine Emperor Leontius to retake the North African city of Carthage, which had been captured by the Arab Umayyads. After seizing the city, this army was pushed back by Umayyad reinforcements and retreated to the island of Crete. As they feared the wrath of Leontius, some officers killed their commander, John the Patrician, and declared Tiberius the emperor. Tiberius swiftly gathered a fleet and sailed for Constantinople, where he then deposed Leontius. Tiberius did not attempt to retake Byzantine Africa from the Umayyads, but campaigned against them along the eastern border with some success. In 705, former emperor Justinian II, who had been deposed by Leontius, led an army of Slavs and Bulgars from the First Bulgarian Empire to Constantinople, and after entering the city secretly, deposed Tiberius. Tiberius fled to Bithynia, but was captured a few months later and beheaded by Justinian between August 705 and February 706. His body was initially thrown into the sea, but was later recovered and buried in a church on the island of Prote.
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, tricked them and secured the Byzantine throne for himself.
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.
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.
The Karabisianoi, sometimes anglicized as the Carabisians, were the main forces of the Byzantine navy from the mid-7th century until the early 8th century. The name derives from the Greek karabos or karabis for "ship", and literally means "people of the ships, sea-men". The Karabisianoi were the first new permanent naval establishment of the Byzantine Empire, formed to confront the Muslim expansion at sea. They were disbanded and replaced with a series of maritime themes some time in 718–730.
The siege of Tyana was carried out by the Umayyad Caliphate in 707–708 or 708–709 in retaliation for a heavy defeat of an Umayyad army under Maimun the Mardaite by the Byzantine Empire in c. 706. The Arab army invaded Byzantine territory and laid siege to the city in summer 707 or 708. The date is uncertain, as virtually each of the extant Greek, Arabic, and Syriac parallel sources has in this respect a different date. Tyana initially withstood the siege with success, and the Arab army faced great hardship during the ensuing winter and was on the point of abandoning the siege in spring, when a relief army sent by Emperor Justinian II arrived. Quarrels among the Byzantine generals, as well as the inexperience of a large part of their army, contributed to a crushing Umayyad victory. Thereupon the inhabitants of the city were forced to surrender. Despite the agreement of terms, the city was plundered and largely destroyed, and according to Byzantine sources its people were made captive and deported, leaving the city deserted.
