The Komnenian Dynasty

Discover the Komnenian dynasty, the Byzantine imperial house that presided over a brilliant cultural revival and partial military recovery from 1081 to 1185. Learn about Alexios I, Anna Komnene, and the Alexiad.

The Komnenian dynasty, which ruled the Byzantine Empire from 1081 to 1185, presided over one of the most brilliant periods in Byzantine cultural history and one of the most important periods in Byzantine political and military history. The dynasty, founded by the general Alexios I Komnenos, came to power in the aftermath of the disaster of Manzikert, when the empire had lost most of Anatolia to the Seljuk Turks. The Komnenian emperors presided over a partial recovery of Byzantine fortunes, an alliance with the Crusaders, and a remarkable flowering of Byzantine literature, art, and theology.

The Komnenian dynasty produced some of the most consequential rulers in Byzantine history, including Alexios I, the founder of the dynasty and the emperor who called on the West for help against the Seljuks; John II, the most pious and the most just of the Komnenian emperors; and Manuel I, the last great Komnenian emperor, who presided over the apogee of the dynasty before its eventual collapse. The dynasty also produced Anna Komnene, the princess-historian who wrote the Alexiad, one of the most important works of Byzantine literature and a major source for the history of the First Crusade.

The study of the Komnenian dynasty is, in practice, the study of one of the enduring elements of the tradition dynasties in Byzantine history, and it makes sense only against the background of the civilization of the medieval Byzantine Empire.

The Founder: Alexios I Komnenos

The Rise to Power

Alexios I Komnenos came to the throne in 1081, after a period of political instability that had followed the death of the last Macedonian emperor, Romanos IV Diogenes, in 1072. The empire was in crisis: most of Anatolia had been lost to the Seljuks, the treasury was empty, and the army was in disarray. Alexios, a young general of the distinguished Komnenos family, was chosen as emperor by the army and the senate, and he was crowned in the Hagia Sophia on 4 April 1081.

Alexios was one of the most capable rulers of the Byzantine Empire, and he was determined to restore the empire’s fortunes. He was a brilliant diplomat and a capable general, and he used both skills to recover some of the lost territory and to reestablish the empire’s prestige. He also had the good fortune to receive a request for military assistance from the West, in the form of the First Crusade, which he used to his advantage.

The First Crusade

The First Crusade, proclaimed in 1095 by Pope Urban II, was originally a Western response to the Seljuk Turkish advance into Anatolia. Alexios saw the Crusade as an opportunity to recover some of the lost Byzantine territory, and he requested military assistance from the Pope in exchange for the reunion of the Eastern and Western churches. The agreement was a turning point in the history of East-West relations, and it set the stage for the eventual Fourth Crusade and the Sack of Constantinople in 1204.

Alexios used the Crusader armies as mercenaries in his campaigns against the Seljuk Turks and the Pechenegs, and he was able to recover some of the lost territory in western Anatolia and the Balkans. The relationship between Alexios and the Crusaders was, however, always tense, and the Byzantines were often frustrated by the undisciplined behavior of the Crusader armies. The relationship eventually deteriorated into mutual suspicion, and the seeds of the eventual Fourth Crusade were sown in the disagreements of the First Crusade.

John II Komnenos: The Good Emperor

The Reign of John II

John II Komnenos, who succeeded his father Alexios in 1118, was one of the most successful and most respected of the Byzantine emperors. He was known as John the Good (Kaloïōannēs) for his piety, his justice, and his military skill. He was a capable general and a wise ruler, and he presided over a period of peace and prosperity for the Byzantine Empire.

John II spent much of his reign on campaign, fighting against the Pechenegs in the Balkans, the Seljuk Turks in Anatolia, the Normans in Sicily, and the Crusader states in the Holy Land. He was successful in all these campaigns, and he was able to recover much of the territory that had been lost after the disaster of Manzikert. He was also a skilled diplomat, and he negotiated a series of treaties with the Crusader states that preserved the peace between the Byzantines and the Crusaders.

John II was also a patron of the arts and learning, and his reign saw a flowering of Byzantine literature, art, and theology. The most famous literary work of his reign was the Alexiad of his daughter Anna Komnene, the princess-historian who wrote the history of her father’s reign. The reign of John II was, a high point of the Komnenian dynasty, and it was the model for the subsequent reigns of his successors.

Manuel I Komnenos: The Last Great Emperor

The Reign of Manuel I

Manuel I Komnenos, who succeeded his father John II in 1143, was the last great emperor of the Komnenian dynasty. Manuel was a brilliant and charismatic ruler, but he was also ambitious and reckless, and his reign saw both the apogee and the beginning of the decline of the dynasty.

Manuel spent much of his reign on campaign, fighting against the Seljuk Turks in Anatolia, the Normans in Sicily, and the Crusader states in the Holy Land. His reign saw both the apogee and the beginning of the decline of the Komnenian restoration.

The decisive event of Manuel’s later years was the Battle of Myriokephalon on 17 September 1176, in which the Byzantine army was ambushed and routed by the Seljuk Sultanate of Rum under Kilij Arslan II in the pass of Myriokephalon in Phrygia. Manuel himself barely escaped with his life, and the army he had carefully rebuilt after the disasters of the early twelfth century was effectively destroyed as a fighting force. Modern historians regard Myriokephalon as the end of any serious Byzantine prospect of recovering the Anatolian interior: the Seljuk Turks, and the Turkish nomads moving into the plateau in their wake, were left in undisputed control of inner Anatolia. The defeat also drained the imperial treasury, exposed the limits of the Komnenian army of mercenaries and allied contingents, and left the dynasty politically and financially exposed.

Anna Komnene and the Alexiad

The Princess-Historian

Anna Komnene, the daughter of Alexios I and the wife of the general Nikephoros Bryennios, was one of the most learned women of the Byzantine world and the author of the Alexiad, one of the most important works of Byzantine literature. The Alexiad is a history of the reign of her father Alexios I, and it is a major source for the history of the First Crusade and the early Komnenian period.

Anna was a brilliant scholar, and she was educated in the classical Greek tradition, including the works of Homer, Plato, Aristotle, and the Greek historians. She was also a skilled writer, and the Alexiad is a masterpiece of Byzantine historical writing, combining the classical tradition with the Christian worldview and the Byzantine political theology.

The Alexiad is the most important literary work of the Komnenian period, and it has been the basis of the modern study of the First Crusade and the early Komnenian period. The work was a major influence on the development of Byzantine historiography, and it has been the model for many later works of Byzantine history.

The Cultural Achievement of the Komnenian Period

Literature and Scholarship

The Komnenian period was a great age of Byzantine literature and scholarship. The most important literary work of the period was the Alexiad of Anna Komnene, but the period also produced many other important works, including the history of John Kinnamos, the history of Niketas Choniates, and the poetry of Theodore Prodromos. The Komnenian period was also a great age of Byzantine theology, and the works of the theologians of the period, including those of Michael Italikos and Nicholas of Methone, were major contributions to the development of Orthodox Christian thought.

The Komnenian period was also a great age of Byzantine art and architecture. The most important surviving buildings of the period include the monastery of the Pantokrator in Constantinople, which was founded by John II and which is one of the most important surviving examples of Komnenian architecture, and the churches of the Daphne monastery near Athens, which are decorated with some of the most important surviving mosaics of the Komnenian period.

The Religious Dimension

The Komnenian period was also a great age of Byzantine religious life. The dynasty was closely associated with the Orthodox Church, and the Komnenian emperors were major patrons of the monasteries and the church. The most famous of the Komnenian monasteries was the Pantokrator monastery in Constantinople, which was founded by John II and which became one of the great religious centers of the Byzantine world.

The Komnenian period also saw the development of the hesychast tradition, which was to become one of the most important spiritual movements of the late Byzantine period. The hesychast tradition, with its emphasis on the Jesus Prayer and the vision of the divine light, was developed in the Byzantine world in the eleventh and twelfth centuries, and it was the basis of the later hesychast controversy of the fourteenth century.

The Decline of the Dynasty

The End of the Komnenian Restoration

The decline of the Komnenian dynasty began with the death of Manuel I in 1180, and it ended with the assassination of Andronikos I in 1185. The successors of Manuel were unable to maintain the dynasty’s power, and the empire was soon plunged into a period of political and financial decline. The most important factor in the decline was the financial exhaustion of the empire, which had been caused by Manuel’s expensive military campaigns and his lavish patronage of the arts.

The end of the Komnenian dynasty in 1185 was followed by a period of political instability, and the empire was soon to be overwhelmed by the catastrophe of the Fourth Crusade in 1204. The Komnenian dynasty had, however, been one of the most important dynasties in Byzantine history, and it had presided over a period of remarkable cultural and political achievement.

The Legacy of the Komnenian Period

The legacy of the Komnenian period is profound, and it is felt in many areas of Byzantine life. The Komnenian period produced some of the most important works of Byzantine literature, including the Alexiad of Anna Komnene, and it was a major influence on the development of Byzantine historiography. The Komnenian period was also a great age of Byzantine art and architecture, and the surviving buildings and mosaics of the period are among the most important examples of Byzantine art.

The Komnenian period also had a profound influence on the development of East-West relations. The Komnenian emperors had negotiated the alliance with the Crusaders, and the relationship between the Byzantines and the Crusaders was one of the defining features of the period. The eventual failure of this relationship, and the catastrophe of the Fourth Crusade, was one of the most important events in the history of the medieval world.

Conclusion

The Komnenian century is the most readable century of Byzantine history. The dynasty was rich enough to keep a first-rate court historian (Anna Komnene, whose Alexiad is a classic of medieval Greek prose), Western enough to attract the attention of every Western historian of the Crusades, and stable enough to be worth studying in its own right rather than as a footnote to the fall. Read in chronological order, Anna’s Alexiad, John Kinnamos’s Epitome, and Niketas Choniates’s History form one of the great narrative sequences of the medieval Mediterranean.
