Komnenian Dynasty and the crusaders  

Posted



  • Alexios I and the First Crusade
After Manzikert, a partial recovery (referred to as the Komnenian restoration) was made possible by the efforts of the Komnenian dynasty. The first emperor of this royal line was Isaac I (1057–1059) and the second Alexios I. At the very outset of his reign, Alexios faced a formidable attack by the Normans under Robert Guiscard and his son Bohemund of Taranto, who captured Dyrrhachium and Corfu, and laid siege to Larissa in Thessaly. Robert Guiscard's death in 1085 temporarily eased the Norman problem. The following year the Seljuq sultan died, and the sultanate was split by internal rivalries. By his own efforts, Alexios defeated the Pechenegs; they were caught by surprise and annihilated at the Battle of Levounion on 28 April 1091.Having achieved stability in the West, Alexios could turn his attention to the severe economic difficulties and the disintegration of the empire's traditional defences. However, he still did not have enough manpower to recover the lost territories in Asia Minor, and to advance against the Seljuks. At the Council of Piacenza in 1095, Alexios' envoys spoke to Pope Urban II about the suffering of the Christians of the East, and underscored that without help from the West they would continue to suffer under Muslim rule. Urban saw Alexius' request as a dual opportunity to cement Western Europe and enhance papal power. On 27 November 1095, Pope Urban II called together the Council of Clermont, and urged all those present to take up arms under the sign of the Cross and launch an armed pilgrimage to recover Jerusalem and the East from the Muslims. The response in Western Europe was overwhelming.





  • John II, Manuel I and the Second Crusade
Alexios' son John II Komnenos succeeded him in 1118, and was to rule until 1143. John was a pious and dedicated emperor who was determined to undo the damage his empire had suffered at the battle of Manzikert, half a century earlier.Famed for his piety and his remarkably mild and just reign, John was an exceptional example of a moral ruler, at a time when cruelty was the norm.For this reason, he has been called the Byzantine Marcus Aurelius. In the course of his twenty-five year reign, John made alliances with the Holy Roman Empire in the west, decisively defeated the Pechenegs at the Battle of Beroia, and personally led numerous campaigns against the Turks in Asia Minor. John's campaigns fundamentally changed the balance of power in the east, forcing the Turks onto the defensive and restoring to the Byzantines many towns, fortresses and cities right across the peninsula.He also thwarted Hungarian, and Serbian threats during the 1120s, and in 1130 allied himself with the German emperor Lothair III against the Norman King Roger II of Sicily. In the later part of his reign John focussed his activities on the East. He defeated the Danishmend emirate of Melitene, and reconquered all of Cilicia, while forceing Raymond of Poitiers, Prince of Antioch, to recognize Byzantine suzerainty. In an effort to demonstrate the Byzantine emperor's role as the leader of the Christian world, John marched into the Holy Land at the head of the combined forces of Byzantium and the Crusader states; yet despite the great vigour with which he pressed the campaign, John's hopes were disappointed by the treachery of his Crusader allies. In 1142 John returned to press his claims to Antioch, but he died in the spring of 1143 following a hunting accident. Raymond was emboldened to invade Cilicia, but he was defeated and forced to go to Constantinople to beg mercy from the new emperor.chosen heir was his fourth son, Manuel I Komnenos, who campaigned aggressively against his neighbours both in the west and in the east. In Palestine, he allied himself with the Crusader Kingdom of Jerusalem and sent a large fleet to participate in a combined invasion of Fatimid Egypt. Manuel reinforced his position as overlord of the Crusader states, with his hegemony over Antioch and Jerusalem secured by agreement with Raynald, Prince of Antioch, and Amalric, King of Jerusalem respectively.In an effort to restore Byzantine control over the ports of southern Italy, he sent an expedition to Italy in 1155, but disputes within the coalition led to the eventual failure of the campaign. Despite this military setback, Manuel's armies successfully invaded the Kingdom of Hungary in 1167, defeating the Hungarians at the Battle of Sirmium. By 1168 nearly the whole of the eastern Adriatic coast lay in Manuel's hands. Manuel made several alliances with the Pope and Western Christian kingdoms, and successfully handled the passage of the Second Crusade through his empire. Although hopes for a lasting Papal-Byzantine alliance came up against insuperable problems, Pope Innocent III clearly had a positive view of Manuel when he told Alexios III that he should imitate "your predecessor Manuel of famous memory" who "always replied favourably to ourselves and our predecessors".In the east, however, Manuel suffered a major defeat at the Battle of Myriokephalon, in 1176, against the Turks. Yet the losses were quickly made good, and in the following year Manuel's forces inflicted a defeat upon a force of "picked Turks". John Vatatzes, who was sent by the Emperor to repel the Turkish invasion, not only brought troops from the capital but also was able to gather an army along the way; a sign that the Byzantine army remained strong and that the defensive program of western Asia Minor was still successful.





  • 12th century Renaissance


John and Manuel pursued active military policies, and both deployed considerable resources on sieges and on city defenses; aggressive fortification policies were at the heart of their imperial military policies. Despite the defeat at Myriokephalon, the policies of Alexios, John and Manuel resulted in vast territorial gains, increased frontier stability in Asia Minor, and secured the stabilization of the empire's European frontiers. From c.1081 to c.1180, the Komnenian army assured the empire's security, enabling Byzantine civilization to flourish.This allowed the Western provinces to achieve an economic revival which continued until the close of the century. It has been argued that Byzantium under the Komnenian rule was more prosperous than at any time since the Persian invasions of the 7th century. During the 12th century population levels rose and extensive tracts of new agricultural land were brought into production. Archaeological evidence from both Europe and Asia Minor shows a considerable increase in the size of urban settlements, together with a notable upsurge in new towns. Trade was also flourishing; the Venetians, the Genoese and others opened up the ports of the Aegean to commerce, shipping goods from the Crusader kingdoms of Outremer and Fatimid Egypt to the west and trading with Byzantium via Constantinople.In artistic terms, there was a revival in mosaic, and regional schools of architecture began producing many distinctive styles that drew on a range of cultural influences. During the 12th century the Byzantines provided their model of early humanism as a renaissance of interest in classical authors. In Eustathius of Thessalonica Byzantine humanism found its most characteristic expression.





Manuel's death on 24 September 1180 left his 11-year-old son Alexios II Komnenos on the throne. Though he was highly incompetent at the office, it was his mother, Maria of Antioch, and her Frankish background that made his regency highly unpopular.Eventually Andronikos I Komnenos, a grandson of Alexios I, launched a revolt against his younger relative and managed to overthrow him in a violent coup d'état. Utilizing his good looks and his immense popularity with the army, he marched on to Constantinople in August 1182, and incited a massacre of the Latins. After eliminating his potential rivals, he had himself crowned as co-emperor in September 1183; he eliminated Alexios II and even took his 12-year-old wife Agnes of France for himself.This troubled succession weakened the dynastic continuity and solidarity on which the strength of the Byzantine state had come to rely.The new emperor was a man of astounding contrasts.Handsome and eloquent, Andronikos was at the same time known for his licentious exploits.Energetic, able and determined, Andronikos had been called a "true Komnenos". However, he was also capable of terrifying brutality, violence and cruelty.Andronikos began his reign well; in particular, the measures he took to reform the government of the empire have been praised by historians. In the provinces Andronikos' reforms produced a speedy and marked improvement. Andronikos's fierce determination to root out corruption and many other abuses was admirable; under Andronikos, the sale of offices ceased; selection was based on merit, rather than favouritism; officials were paid an adequate salary so as to reduce the temptation of bribery. Every form of corruption was eliminated with ferocious zeal.The people, who felt the severity of his laws, at the same time acknowledged their justice, and found themselves protected from the rapacity of their superiors. Andronikos's energetic efforts to rein in the oppressive tax collectors and officials of the empire did much to alleviate the lot of the peasantry. However, his efforts to check the power of the nobility were considerably more problematic. The aristocrats were infuriated against him, and to make matters worse, Andronikos seems to have become increasingly unbalanced; executions and violence became increasingly common, and his reign turned into a reign of terror.Andronikos seemed almost to seek the extermination of the aristocracy as a whole. The struggle against the aristocracy turned into wholesale slaughter, while the emperor resorted to ever more ruthless measures to shore up his regime.Despite his military background, Andronikos failed to deal with Isaac Komnenos, Béla III who reincorporated Croatian territories into Hungary, and Stephen Nemanja of Serbia who declared his independence from Byzantium. Yet none of these troubles would compare to the William's of Sicily invasion force of 300 ships and 80,000 men, arriving in 1185.Andronikos mobilized a small fleet of 100 ships to defend the capital but other than that he was indifferent to the populace. He was finally overthrown when Isaa Angelos, surviving an Imperial assassination attempt, marched on to the Hagia Sophia and with the aid of the people seized power and had Andronikos killed.Iconium is won by the Third Crusade.The reign of Isaac II , and, still more, that of his brother Alexios III, saw the collapse of what remained of the centralized machinery of Byzantine government and defense. Although, the Normans were driven out of Greece, in 1186 the Bulgars began a rebellion that was to lead to the formation of the Second Bulgarian Empire. The mismanagement of the Third Crusade clearly demonstrated Byzantium's weaknesses under the Angeli. When Richard I of England appropriated Cyprus from its ruler, Isaac Komnenos, he refused to hand it back to the Empire, And when Frederick Barbarossa conquered Iconium, Isaac failed to seize the initiative.The internal policy of the Angeloi was characterized by the squandering of the public treasure, and the fiscal maladministration. Byzantine authority was severely weakened, and the growing power vacuum at the centre of the empire encouraged fragmentation. There is evidence that some Komnenian heirs had set up a semi-independent state in Trebizond before 1204. According to Alexander Vasiliev, "the dynasty of the Angeloi, Greek in its origin, [...] accelerated the ruin of the Empire, already weakened without and disunited within.





  • Fourth Crusade


In 1198, Pope Innocent III broached the subject of a new crusade through legates and encyclical letters. The stated intent of the crusade was to conquer Egypt, now the centre of Muslim power in the Levant. The crusader army that arrived at Venice in the summer of 1202 was somewhat smaller than had been anticipated, and there were not sufficient funds to pay the Venetians, whose fleet was hired by the crusaders to take them to Egypt. Venetian policy under the aging and blind but still ambitious Doge Enrico Dandolo was potentially at variance with that of the Pope and the crusaders, because Venice was closely related commercially with Egypt.The crusaders accepted the suggestion that in lieu of payment they assist the Venetians in the capture of the (Christian) port of Zara in Dalmatia (vassal city of Venice, which had rebelled and placed itself under Hungary's protection in 1186).The city fell in November 1202 after a brief siege. Innocent, who was informed of the plan, but his veto was disregarded, was reluctant to jeopardize the Crusade, and gave conditional absolution to the crusaders—not, however, to the Venetians.After the death of Theobald III, Count of Champagne, the leadership of the Crusade passed to Boniface of Montferrat, a friend of the Hohenstaufen Philip of Swabia. Both Boniface and Philip had married into the Byzantine imperial family. In fact, Philip's brother-in-law, Alexios Angelos, son of the deposed and blinded emperor Isaac II Angelos, had appeared in Europe seeking aid and had made contacts with the crusaders. Alexios offered to reunite the Byzantine church with Rome, pay the crusaders 200,000 silver marks, and join the crusade with 200,000 silver marks and all the supplies they needed to get to Egypt.Innocent was aware of a plan to divert the Crusade to Constantinople, and forbade any attack on the city; but the papal letter arrived after the fleets had left Zara.Alexios III made no preparations for the defense of the city; thus, when the Venetian fleet entered the waters of Constantinople on June 24, 1203, they encountered little resistance.In the summer of 1203 Alexios III fled, and Alexios Angelos was elevated to the throne as Alexios IV along with his blind father Isaac. Innocent reprimanded the leaders of the crusaders, and ordered them to proceed forthwith to the Holy Land."None of you should therefore dare to assume that it is permissible for you to seize or to plunder the land of the Greeks, even though the latter may be disobedient to the Apostolic See, or on the grounds that the Emperor of Constantinople has deposed and even blinded his brother and usurped the imperial throne. For though this same emperor and the men entrusted to his rule may have sinned, both in these and in other matters, it is not for you to judge their faults, nor have you assumed the sign of the cross to punish this injury; rather you specifically pledged your self to the duty of avenging the insult to the cross."Innocent III to Boniface I of Montferrat, Baldwin IX, Count of Flanders, and Louis I, Count of Blois (Ferentino, summer 1203, c. June 20).When in late November 1203 Alexios IV announced that his promises were hard to keep as the empire was short on funds (he had managed to pay roughly half of the promised amount of 200,000 silver marks, and could not fulfil his promise that he would cover the Venetians' rent of the fleet for the crusaders., the crusaders declared war on him. Meanwhile, internal opposition to Alexios IV grew, and, on January 25, 1204, one of his courtiers, Alexios Doukas killed him, and took the throne himself as Alexios V; Isaac died soon afterwards, probably naturally.The crusaders and Venetians, incensed at the murder of their supposed patron, prepared to assault the Byzantine capital. They decided that 12 electors (six Venetians and six crusaders) should choose a Latin emperor.Map to show the partition of the empire following the Fourth Crusade, c.1204.Eventually, the crusaders took the city on April 13, 1204. Constantinople was subjected by the rank and file to pillage and massacre for three days. Many priceless icons, relics, and other objects later turned up in Western Europe, a large number in Venice. According to Choniates, a prostitute was even set up on the Patriarchal throne.When Innocent III heard of the conduct of his crusaders, he castigated them in no uncertain terms. But the situation was beyond his control, especially after his legate, on his own initiative, had absolved the crusaders from their vow to proceed to the Holy Land. When order had been restored, the crusaders and the Venetians proceeded to implement their agreement; Baldwin of Flanders was elected emperor and the Venetian Thomas Morosini chosen patriarch. The lands parcelled out among the leaders did not include all the former Byzantine possessions. The Byzantine rule continued in Nicaea, Trebizond, and Epirus
