Twenty Years' Anarchy
Leo III the Isaurian also known as the Syrian (Greek: Λέων Γ΄ ὁ Ἴσαυρος, Leōn III ho Isauros), (c. 685 – 18 June 741) was Byzantine Emperor from 717 until his death in 741. He put an end to a period of instability, successfully defended the Empire against the invading Umayyads, and forbade the veneration of icons.
Leo, whose original name was Konon, was born in Germanikeia in the Syrian province of Commagene (modern Kahramanmaraş in Turkey). Some, including the Byzantine chronicler Theophanes, have claimed that Konon's family had been resettled in Thrace, where he entered the service of Emperor Justinian II, when the latter was advancing on Constantinople with an army of 100,000 horsemen provided by Tervel of Bulgaria in 705.
After the victory of Justinian II, Konon was dispatched on a diplomatic mission to Alania and Lazica to organize an alliance against the Umayyad Caliphate under Al-Walid I. Konon was appointed commander (stratēgos) of the Anatolic theme by Emperor Anastasius II. On his deposition, Konon joined with his colleague Artabasdus, the stratēgos of the Armeniac theme, in conspiring to overthrow the new Emperor Theodosius III. Artabasdus was betrothed to Anna, daughter of Leo as part of the agreement.
Siege of Constantinople
Leo entered Constantinople on 25 March 717 and forced the abdication of Theodosios III, becoming emperor as Leo III. The new Emperor was immediately forced to attend to the Second Arab siege of Constantinople, which commenced in August of the same year. The Arabs were Umayyad forces sent by Caliph Sulayman ibn Abd al-Malik and serving under his brother Maslama ibn Abd al-Malik. They had taken advantage of the civil discord in the Byzantine Empire to bring a force of 80,000 to 150,000 men and a massive fleet to the Bosphorus.
Careful preparations, begun three years earlier under Anastasius II, and the stubborn resistance put up by Leo wore out the invaders. An important factor in the victory of the Byzantines was their use of Greek fire. The Arab forces also fell victim to Bulgarian reinforcements arriving to aid the Byzantines. Leo was allied with the Bulgarians but the chronicler Theophanes the Confessor was uncertain if they were still serving under Tervel or his eventual successor Kormesiy of Bulgaria.
Unable to continue the siege in the face of the Bulgarian onslaught, the impenetrability of Constantinople's walls, and their own exhausted provisions, the Arabs were forced to abandon the siege in August, 718. Sulayman himself had died the previous year and his successor Umar II would not attempt another siege. The siege had lasted 12 months.
Having thus preserved the Empire from extinction, Leo proceeded to consolidate its administration, which in the previous years of anarchy had become completely disorganized. In 718 he suppressed a rebellion in Sicily and in 719 did the same on behalf of the deposed Emperor Anastasios II.
Leo secured the Empire's frontiers by inviting Slavic settlers into the depopulated districts and by restoring the army to efficiency; when the Umayyad Caliphate renewed their invasions in 726 and 739, as part of the campaigns of Hisham ibn Abd al-Malik, the Arab forces were decisively beaten, particularly at Akroinon in 740. His military efforts were supplemented by his alliances with the Khazars and the Georgians.
Leo undertook a set of civil reforms including the abolition of the system of prepaying taxes which had weighed heavily upon the wealthier proprietors, the elevation of the serfs into a class of free tenants and the remodelling of family, maritime law and criminal law, notably substituting mutilation for the death penalty in many cases. The new measures, which were embodied in a new code called the Ecloga (Selection), published in 726, met with some opposition on the part of the nobles and higher clergy. The Emperor also undertook some reorganization of the theme structure by creating new themata in the Aegean region.
Leo's most striking legislative reforms dealt with religious matters, especially iconoclasm ("Icon-breaking," therefore an iconoclast is an "Icon-breaker"). After an apparently successful attempt to enforce the baptism of all Jews and Montanists in the empire (722), he issued a series of edicts against the worship of images (726–729). This prohibition of a custom which had been in use for centuries seems to have been inspired by a genuine desire to improve public morality, and received the support of the official aristocracy and a section of the clergy. A majority of the theologians and all the monks opposed these measures with uncompromising hostility, and in the western parts of the Empire the people refused to obey the edict.
A revolt which broke out in Greece, mainly on religious grounds, was crushed by the imperial fleet in 727 (cf. Agallianos Kontoskeles). In 730, Patriarch Germanos I of Constantinople resigned rather than subscribe to an iconoclastic decree. Leo had him replaced by Anastasios, who willingly sided with the Emperor on the question of icons. Thus Leo suppressed the overt opposition of the capital.
In the Italian Peninsula, the defiant attitude of Popes Gregory II and Gregory III on behalf of image-veneration led to a fierce quarrel with the Emperor. The former summoned councils in Rome to anathematize and excommunicate the iconoclasts (730, 732); In 740 Leo retaliated by transferring Southern Italy and Illyricum from the papal diocese to that of the Patriarch of Constantinople. The struggle was accompanied by an armed outbreak in the exarchate of Ravenna in 727, which Leo finally endeavoured to subdue by means of a large fleet. But the destruction of the armament by a storm decided the issue against him; his southern Italian subjects successfully defied his religious edicts, and the Exarchate of Ravenna became effectively detached from the Empire.
The emperor died of dropsy in June 741.
With his wife Maria, Leo III had four known children:
