Historical Information

In the 730s Leo III carried out extensive repairs of the Theodosian walls, which had been damaged by frequent and violent attacks; this work was financed by a special tax on all the subjects of the Empire.

Theodora, widow of the emperor Theophilus (d. 842) acted as regent during the minority of her son Michael III, who was said to have been introduced to dissolute habits by her brother Bardas. When Michael assumed power in 856 he became known for excessive drunkenness, appeared in the hippodrome as a charioteer and burlesqued the religious processions of the clergy. He removed Theodora from the Great Palace to the Carian Palace and later to the monastery of Gastria, but after the death of Bardas she was released to live in the palace of St Mamas; she also had a rural residence at the Anthemian Palace, where Michael was assassinated in 867.

In 865 an attack was made on the city by a new principality set up a few years earlier at Novgorod by Rurik, a Varangian chief: two hundred small Russian vessels passed through the Bosporus and plundered the monasteries and other properties on the suburban Prince's Islands. Oryphas, the admiral of the Byzantine fleet, alerted the emperor Michael, who promptly put the invaders to flight; but the suddenness and savagery of the onslaught made a deep impression on the citizens.

In 980 the emperor Basil II received an unusual gift from Prince Vladimir of Kiev: 6,000 Varangian warriors which Basil formed into a new bodyguard known as the Varangian Guard. They were known for their ferocity, honour and loyalty. It is said that in 1038 they were dispersed in winter quarters in the Thracesian theme when one of their number attempted to violate a countrywoman, but in the struggle she seized his sword and killed him; instead of taking revenge, however, his comrades applauded her conduct, compensated her with all his possessions, and exposed his body without burial as if he had committed suicide. However, following the death of an emperor, they became known also for plunder in the imperial palaces. Later in the 11th Century the Varangian Guard became dominated by Anglo-Saxons who preferred this way of life to subjugation by the new Norman kings of England.

The Book of the Eparch, which dates to the 10th century, gives a detailed picture of the city's commercial life and its organization at that time. The corporations in which the tradesmen of Constantinople were organised were supervised by the Eparch, who regulated such matters as production, prices, import and export. Each guild had its own monopoly, and tradesmen might not belong to more than one. It is an impressive testament to the strength of tradition how little these arrangements had changed since the office, then known by the Latin version of its title, had been set up in 330 to mirror the urban prefecture of Rome.

In the 9th and 10th centuries, the Constantinople had a population of between 500,000 and 800,000.


The Iconoclast Controversy, 730–787, 814–842
In the eighth and ninth centuries the iconoclast movement caused serious political unrest throughout the Empire. The emperor Leo III issued a decree in 726 against images, and ordered the destruction of a statue of Christ over one of the doors of the Chalke, an act which was fiercely resisted by the citizens.[28] Constantine V convoked a church council in 754 which condemned the worship of images, after which many treasures were broken, burned, or painted over with depictions of trees, birds or animals: one source refers to the church of the Holy Virgin at Blachernae as having been transformed into a "fruit store and aviary".[29] Following the death of his son Leo IV in 780, the empress Irene restored the veneration of images through the agency of the Second Council of Nicaea in 787.

The iconoclast controversy returned in the early 9th century, only to be resolved once more in 843 during the regency of Empress Theodora, who restored the icons. These controversies contributed to the deterioration of relations between the Western and the Eastern Churches.

Prelude to the Comnenian period, 1025–1081
In the late 11th century catastrophe struck with the unexpected and calamitous defeat of the imperial armies at the Battle of Manzikert in Armenia in 1071. The Emperor Romanus Diogenes was captured. The peace terms demanded by Alp Arslan, sultan of the Seljuk Turks, were not excessive, and Romanus accepted them. On his release, however, Romanus found that enemies had placed their own candidate on the throne in his absence; he surrendered to them and suffered death by torture, and the new ruler, Michael VII Ducas, refused to honour the treaty. In response, the Turks began to move into Anatolia in 1073. The collapse of the old defensive system meant that they met no opposition, and the empire's resources were distracted and squandered in a series of civil wars. Thousands of Turkoman tribesmen crossed the unguarded frontier and moved into Anatolia. By 1080, a huge area had been lost to the empire, and the Turks were within striking distance of Constantinople.


[b] The Comneni, 1081–1185

The Byzantine Empire under Manuel I, c. 1180

Emperor John II (1118–1143) is shown on the left, with the Virgin Mary and infant Jesus in the centre, and John's consort Empress Irene on the right.Under the Comnenian dynasty (1081–1185), Byzantium staged a remarkable military, financial and territorial recovery. In what is sometimes called the Comnenian Restoration, with the establishment of a new military system, the Empire recovered nearly half of the lost Anatolian lands. In 1090–91, the nomadic Pechenegs reached the walls of Constantinople, where Emperor Alexius I with the aid of the Kipchaks annihilated their army.[30] The battle of Levounion in 1091 marked the beginning of a resurgence of Byzantine power and influence that would last for a hundred years. In response to a call for aid from Alexius I Comnenus, the First Crusade assembled at Constantinople in 1096, but declining to put itself under Byzantine command set out for Jerusalem on its own account.[31] John II built the monastery of the Pantocrator (Almighty) with a hospital for the poor of 50 beds.[32]

With the restoration of firm central government, the empire became fabulously wealthy. The population was rising (estimates for Constantinople in the twelfth century vary from approximately 100,000 to 500,000), and towns and cities across the realm flourished. Meanwhile, the volume of money in circulation dramatically increased. This was reflected in Constantinople by the construction of the Blachernae palace, the creation of brilliant new works of art, and general prosperity at this time: an increase in trade, made possible by the growth of the Italian city-states, may have helped the growth of the economy. Certainly, the Venetians and others were active traders in Constantinople, making a living out of shipping goods between the Crusader Kingdoms of Outremer and the West while also trading extensively with Byzantium and Egypt. The Venetians had factories on the north side of the Golden Horn, and large numbers of westerners were present in the city throughout the twelfth century. Towards the end of Manuel I's reign, the number of foreigners in the city reached about 60,000-80,000 people out of a total population of about 400,000 people.[33] In 1171, Constantinople also contained a small community of 2,500 Jews.[34]

In artistic terms, the 12th century was a very productive period. There was a revival in the mosaic art, for example: mosaics became more realistic and vivid, with an increased emphasis on depicting three-dimensional forms. There was an increased demand for art, with more people having access to the necessary wealth to commission and pay for such work. According to N.H. Baynes (Byzantium, An Introduction to East Roman Civilization):

"With its love of luxury and passion for colour, the art of this age delighted in the production of masterpieces that spread the fame of Byzantium throughout the whole of the Christian world. Beautiful silks from the work-shops of Constantinople also portrayed in dazzling colour animals - lions, elephants, eagles, and griffins - confronting each other, or represented Emperors gorgeously arrayed on horseback or engaged in the chase."
"From the tenth to the twelfth century Byzantium was the main source of inspiration for the West. By their style, arrangement, and iconography the mosaics of St. Mark's at Venice and of the cathedral at Torcello clearly reveal their Byzantine origin. Similarly those of the Palatine Chapel, the Martorana at Palermo, and the cathedral of Cefalù, together with the vast decoration of the cathedral at Monreale, demonstrate the influence of Byzantium on the Norman Court of Sicily in the twelfth century. Hispano-Moorish art was unquestionably derived from the Byzantine. Romanesque art owes much to the East, from which it borrowed not only its decorative forms but the plan of some of its buildings, as is proved, for instance, by the domed churches of south-western France. Princes of Kiev, Venetian doges, abbots of Monte Cassino, merchants of Amalfi, and the kings of Sicily all looked to Byzantium for artists or works of art. Such was the influence of Byzantine art in the twelfth century, that Russia, Venice, southern Italy and Sicily all virtually became provincial centres dedicated to its production."

The Entry of the Crusaders into Constantinople, by Eugène Delacroix, 1840.
The Latin Empire, Empire of Nicaea, Empire of Trebizond, and the Despotate of Epirus. The borders are very uncertainIn the course of a plot between Philip of Swabia, Boniface of Montferrat and the Doge of Venice, the Fourth Crusade was, despite papal excommunication, diverted in 1203 against Constantinople, ostensibly promoting the claims of Alexius son of the deposed emperor Isaac. The reigning emperor Alexius III had made no preparation. The Crusaders occupied Galata, broke the chain protecting the Golden Horn and entered the harbour, where on 27 July they breached the sea walls: Alexius III fled. But the new Alexius IV found the Treasury inadequate, and was unable to make good the rewards he had promised to his western allies. Tension between the citizens and the Latin soldiers increased. In January 1204 the protovestiarius Alexius Murzuphlus provoked a riot, probably to intimidate Alexius IV, but whose only result was the destruction of the great statue of Athena, the work of Phidias, which stood in the principal forum facing west.

In February the people rose again: Alexius IV was imprisoned and executed, and Murzuphlus took the purple as Alexius V. He made some attempt to repair the walls and organise the citizenry, but there had been no opportunity to bring in troops from the provinces and the guards were demoralised by the revolution. An attack by the Crusaders on 6 April failed, but a second from the Golden Horn on 12 April succeeded, and the invaders poured in. Alexius V fled. The Senate met in St Sophia and offered the crown to Theodore Lascaris, who had married into the Angelid family, but it was too late. He came out with the Patriarch to the Golden Milestone before the Great Palace and addressed the Varangian Guard. Then the two of them slipped away with many of the nobility and embarked for Asia. By the next day the Doge and the leading Franks were installed in the Great Palace, and the city was given over to pillage for three days.

The great historian of the Crusades, Sir Steven Runciman, wrote that the sack of Constantinople is “unparalleled in history”.

“For nine centuries,” he goes on, “the great city had been the capital of Christian civilisation. It was filled with works of art that had survived from ancient Greece and with the masterpieces of its own exquisite craftsmen. The Venetians wherever they could seized treasures and carried them off. But the Frenchmen and Flemings were filled with a lust for destruction: they rushed in a howling mob down the streets and through the houses, snatching up everything that glittered and destroying whatever they could not carry, pausing only to murder or to rape, or to break open the wine-cellars. Neither monasteries nor churches nor libraries were spared. In St Sophia itself drunken soldiers could be seen tearing down the silken hangings and pulling the silver iconostasis to pieces, while sacred books and icons were trampled under foot. While they drank from the altar-vessels a prostitute sang a ribald French song on the Patriarch’s throne. Nuns were ravished in their convents. Palaces and hovels alike were wrecked. Wounded women and children lay dying in the streets. For three days the ghastly scenes continued until the huge and beautiful city was a shambles. Even after order was restored, citizens were tortured to make them reveal treasures they had hidden."

For the next half-century, Constantinople was the seat of the Latin Empire. The Byzantine nobility were scattered. Many went to Nicaea, where Theodore Lascaris set up an imperial court, or to Epirus, where Theodore Angelus did the same; others fled to Trebizond, where one of the Comneni had already with Georgian support established an independent seat of empire. Nicaea and Epirus both vied for the imperial title, and tried to recover Constantinople. In 1261, Constantinople was captured from its last Latin ruler, Baldwin II, by the forces of the Nicaean emperor Michael VIII Palaeologus.


The Palaeologi, 1261–1453
Although Constantinople was retaken by Michael VIII, the Empire had lost many of its key economic resources, and struggled to survive. The palace of Blachernae in the north-west of the city became the main Imperial residence, with the old Great Palace on the shores of the Bosporus going into decline. When Michael VIII captured the city, its population was 35,000 people, but by the end of his reign, he had succeeded in increasing the population to about 70,000 people. The Emperor achieved this by summoning former residents, who had fled the city when the Crusaders captured it, back, and by relocating Greeks from the recently reconquered Peloponnese to the capital. In 1347, the Black Death spread to Constantinople. In 1453, when the Ottoman Turks captured the city, it contained approximately 50,000 people.
