Manuel I Komnenos
Manuel I Komnenos, Latinized as Comnenus, also called Porphyrogenitus, was a Byzantine emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire experienced a resurgence of military and economic power and enjoyed a cultural revival.
Eager to restore his empire to its past glories as the great power of the Mediterranean world, Manuel pursued an energetic and ambitious foreign policy. In the process he made alliances with Pope Adrian IV and the resurgent West. He invaded the Norman Kingdom of Sicily, although unsuccessfully, being the last Eastern Roman emperor to attempt reconquests in the western Mediterranean. The passage of the potentially dangerous Second Crusade through his empire was adroitly managed. Manuel [|established a Byzantine protectorate] over the Crusader states of Outremer. Facing Muslim advances in the Holy Land, he made common cause with the Kingdom of Jerusalem and participated in a combined invasion of Fatimid Egypt. Manuel reshaped the political maps of the Balkans and the eastern Mediterranean, placing the kingdoms of Hungary and Outremer under Byzantine hegemony and campaigning aggressively against his neighbours both in the west and in the east.
However, towards the end of his reign, Manuel's achievements in the east were compromised by a serious defeat at Myriokephalon, which in large part resulted from his arrogance in attacking a well-defended Seljuk position. Although the Byzantines recovered and Manuel concluded an advantageous peace with Sultan Kilij Arslan II, Myriokephalon proved to be the final, unsuccessful effort by the empire to recover the interior of Anatolia from the Turks.
Called ho Megas by the Greeks, Manuel is known to have inspired intense loyalty in those who served him. He also appears as the hero of a history written by his secretary, John Kinnamos, in which every virtue is attributed to him. Manuel, who was influenced by his contact with western Crusaders, enjoyed the reputation of "the most blessed emperor of Constantinople" in parts of the Latin world as well. Some historians have been less enthusiastic about him, however, asserting that the great power he wielded was not his own personal achievement, but that of the Komnenos dynasty he represented. Further, it has also been argued that since Byzantine imperial power declined catastrophically after Manuel's death, it is only natural to look for the causes of this decline in his reign.
Youth
Manuel Komnenos was born on 28 November 1118 in the Purple Chamber of the Great Palace of Constantinople. He was the eighth child and fourth son of John II Komnenos, the newly-crowned emperor of the Byzantine Empire, and Irene of Hungary. Manuel's eldest brother, Alexios, was crowned co-emperor, and Niketas Choniates narrates that in 1123 John raised Manuel and Manuel's other older brothers, Andronikos and Isaac, to the rank of sebastokratores.Manuel was raised alongside his cousin Andronikos, with whom he became close. He did not receive a formal education, and was trained to be a soldier. He accompanied his father on military expeditions against the Anatolian Turks. On one occasion he led his personal attendants in a counterattack, which reversed the course of an engagement which was favouring the enemy. This occurred during the unsuccessful Siege of Neocaesarea, against the Danishmendid Turks. Manuel favourably impressed his father by his courage and fortitude, John praising him as the 'Saviour of the Romans', though he also criticised his rashness.
As part of his policy concerning the crusader states, John II groomed Manuel to marry Princess Constance of Antioch. John hoped that Manuel would become the master of a large domain, consisting of Attalia, Cyprus, Cilicia and Antioch. The Antiochenes, though ready to swear fealty to the Byzantine emperor, proved reluctant to accept any real level of Byzantine control. Manuel's eldest brothers, Alexios and Andronikos, died in 1142.
Accession
In 1143 John II lay dying as a result of an infected wound; on his deathbed he chose Manuel as his successor, in preference to his elder surviving brother Isaac. John cited Manuel's courage and readiness to take advice, in contrast to Isaac's irascibility and unbending pride, as the reasons for his choice. After John died on 8 April 1143, Manuel was acclaimed emperor by the armies. Yet his succession was by no means assured: with his father's army in the wilds of Cilicia far from Constantinople, he recognised that it was vital he should return to the capital as soon as possible. He still had to take care of his father's funeral, and tradition demanded he organise the foundation of a monastery on the spot where his father died. Swiftly, he dispatched the megas domestikos John Axouch ahead of him, with orders to arrest his most dangerous potential rival, his brother Isaac, who was living in the Great Palace with instant access to the imperial treasure and regalia. Axouch arrived in the capital even before news of the emperor's death had reached it. He quickly secured the loyalty of the city, and when Manuel entered the capital in August 1143, he was crowned by the new patriarch, Michael II Kourkouas. A few days later, with nothing more to fear as his position as emperor was now secure, Manuel ordered the release of Isaac. Then he ordered two golden pieces to be given to every householder in Constantinople and 200 pounds of gold to be given to the Byzantine Church.The empire that Manuel inherited from his father was in a more stable position than it had been a century earlier. In the late 11th century, the Byzantine Empire had faced marked military and political decline, but this decline had been arrested and largely reversed by the leadership of Manuel's grandfather and father. Nevertheless, the empire continued to face formidable challenges. By 1071, the Normans of Sicily had removed southern Italy from the control of the Byzantine emperor. Following the Battle of Manzikert, also in 1071, the Seljuk Turks had done the same with most of Anatolia, retaining control of the central plateau thereafter. And in the Levant, a new force had appeared—the Crusader states—which presented the Byzantine Empire with new challenges. Now, more than at any time during the preceding centuries, the task facing the emperor was daunting indeed.
Second Crusade and Raynald of Châtillon
Prince of Antioch
The first test of Manuel's reign came in 1144, when he was faced with a demand by Raymond, Prince of Antioch, for the cession of Cilician territories. However, later that year the crusader County of Edessa was engulfed by the tide of a resurgent Islamic jihad under Imad ad-Din Zengi. Raymond realized that immediate help from the west was out of the question. With his eastern flank now dangerously exposed to this new threat, there seemed little option but for him to prepare for a humiliating visit to Constantinople. Swallowing his pride, he made the journey north to submit to Manuel and ask for protection. He was promised the support that he had requested, and his allegiance to Byzantium was secured.Expedition against Konya
In 1146 Manuel assembled his army at the military base Lopadion and set out on a punitive expedition against Mas'ud, the Sultan of Rûm, who had been repeatedly violating the frontiers of the Empire in western Anatolia and Cilicia. There was no attempt at a systematic conquest of territory, but Manuel's army defeated the Turks at Acroënus, before capturing and destroying the fortified town of Philomelion, removing its remaining Christian population. The Byzantine forces reached Masud's capital, Konya, and ravaged the area around the city, but could not assault its walls. Among Manuel's motives for mounting this razzia there included a wish to be seen in the West as actively espousing the crusading ideal; Kinnamos also attributed to Manuel a desire to show off his martial prowess to his new bride. While on this campaign Manuel received a letter from Louis VII of France announcing his intention of leading an army to the relief of the crusader states.Arrival of the Crusaders
Manuel was prevented from capitalising on his conquests by events in the Balkans that urgently required his presence. In 1147 he granted a passage through his dominions to two armies of the Second Crusade under Conrad III of Germany and Louis VII of France. At this time, there were still members of the Byzantine court who remembered the passage of the First Crusade, a defining event in the collective memory of the age that had fascinated Manuel's aunt, Anna Komnene.Many Byzantines feared the Crusade, a view endorsed by the numerous acts of vandalism and theft practised by the unruly armies as they marched through Byzantine territory. Byzantine troops followed the Crusaders, attempting to police their behaviour, and further troops were assembled in Constantinople, ready to defend the capital against any acts of aggression. This cautious approach was well advised, but still the numerous incidents of covert and open hostility between the Franks and the Greeks on their line of march, for which it seems both sides were to blame, precipitated conflict between Manuel and his guests. Manuel took the precaution—which his grandfather had not taken—of making repairs to the city walls, and he pressed the two kings for guarantees concerning the security of his territories. Conrad's army was the first to enter the Byzantine territory in the summer of 1147, and it figures more prominently in the Byzantine sources, which imply that it was the more troublesome of the two. Indeed, the contemporary Byzantine historian Kinnamos describes a full-scale clash between a Byzantine force and part of Conrad's army, outside the walls of Constantinople. The Byzantines defeated the Germans and, in Byzantine eyes, this reverse caused Conrad to agree to have his army speedily ferried across to Damalis on the Asian shore of the Bosphoros.
After 1147, however, the relations between the two leaders became friendlier. By 1148 Manuel had seen the wisdom of securing an alliance with Conrad, whose sister-in-law Bertha of Sulzbach he had earlier married; he actually persuaded the German king to renew their alliance against Roger II of Sicily. Unfortunately for the Byzantine emperor, Conrad died in 1152, and despite repeated attempts, Manuel could not reach an agreement with his successor, Frederick Barbarossa.
