The Battle of Manzikert in 1071

Explore the Battle of Manzikert in 1071, the catastrophic defeat of the Byzantine army by the Seljuk Turks that led to the loss of Anatolia. Learn about Emperor Romanos Diogenes and the consequences for the empire.

The Battle of Manzikert, fought on 26 August 1071 between the Byzantine Empire and the Seljuk Turkish Empire, was one of the most consequential military defeats in medieval history. The battle, fought in eastern Anatolia near the fortress of Manzikert (modern Malazgirt), resulted in the capture of the Byzantine emperor Romanos IV Diogenes by the Seljuk sultan Alp Arslan. The battle and its aftermath led to the loss of most of Anatolia, the empire’s recruiting ground and economic heartland, and it began a process of decline that would lead eventually to the fall of Constantinople in 1453.

The Battle of Manzikert was not, in itself, the immediate end of the Byzantine Empire, but it was the beginning of a long process of territorial loss, internal instability, and external pressure that transformed the empire from a major Mediterranean power into a small Balkan state. To understand the Battle of Manzikert is to understand one of the pivotal moments in the history of the medieval Mediterranean.

The Background

The Seljuk Threat

The Seljuk Turks, originally a nomadic people from Central Asia, had converted to Islam in the tenth century and had established a vast empire stretching from Central Asia to the eastern Mediterranean. The Great Seljuk Empire, founded by Tughril and his brother Chaghri, had captured Baghdad in 1055, and the Seljuk sultan Alp Arslan, who came to the throne in 1063, had expanded the empire into Armenia, Georgia, and eastern Anatolia.

The Seljuk expansion into eastern Anatolia threatened the Byzantine Empire directly, since Anatolia was the empire’s recruiting ground, its economic heartland, and the source of much of its grain and other agricultural production. The Seljuk raids into Anatolia, which had been a constant problem since the late 1040s, had already cost the empire much of its eastern provinces, and the Byzantine government had been forced to pay tribute to the Seljuks to halt the raids.

The Reign of Romanos Diogenes

The Byzantine emperor at the time of the battle, Romanos IV Diogenes, had come to the throne in 1068, after a series of coups and civil wars had destabilized the Macedonian dynasty. Romanos was a capable soldier, and he was determined to recover the lost provinces of the empire and to halt the Seljuk expansion. He raised a large army, including mercenaries from all over the empire and from the West, and he led it east in the spring of 1071.

The Byzantine army was a formidable force, including the imperial guard, the thematic troops of Anatolia, the mercenary forces of the Balkans, and the heavy cavalry of the West. The army is estimated to have numbered between 40,000 and 70,000 men, although the exact size is unknown. The army marched east through Anatolia, and it arrived at the fortress of Manzikert in August 1071.

The Battle

The Negotiations

Before the battle, the two sides engaged in a series of negotiations, with Romanos offering to pay tribute to the Seljuks in exchange for peace, and Alp Arslan demanding the return of the Anatolian provinces that the Byzantines had taken. The negotiations failed, and the two sides prepared for battle.

The two armies met on the plain of Manzikert, near the fortress, on 26 August 1071. The battle began in the early morning, with the Byzantine army drawn up in a line facing the Seljuk forces. The Seljuk army was smaller than the Byzantine, with perhaps 20,000 to 30,000 men, but it included a strong force of Turkish horse archers, who were among the most effective cavalry in the medieval world.

The Course of the Battle

The battle began with a series of cavalry charges by the Byzantine forces, but the Seljuk horse archers, who were highly mobile and skilled at the Parthian shot, repeatedly repulsed the Byzantine charges. The Seljuk horse archers, fighting a classic steppe tactic, would feign retreat, then turn and shoot at the pursuing Byzantine cavalry, inflicting heavy losses.

The battle was decided by a combination of factors. First, the Byzantine army, which was drawn from many different regions and included many mercenaries, was not well integrated, and many of the units failed to cooperate. Second, the Byzantine army was short of supplies, and the soldiers were suffering from thirst and hunger. Third, the Byzantine army was led by a commander, Romanos, who was not familiar with the steppe tactics of the Seljuks, and who committed several tactical errors.

The decisive moment came when a group of Byzantine soldiers, led by the general Andronikos Doukas, the son of the emperor’s rival John Doukas, abandoned the field. The defection, which was part of a palace conspiracy against Romanos, opened a gap in the Byzantine line, and the Seljuk forces, who had been watching for such an opportunity, exploited it. The Byzantine army broke, and the emperor was captured by the Seljuks.

The Aftermath

The Treatment of the Emperor

The Seljuk sultan Alp Arslan treated the captured Byzantine emperor with great courtesy. According to the famous account, Alp Arslan, who had expected to be received with haughtiness, was reportedly treated with respect, and the two emperors dined together. Alp Arslan is said to have treated Romanos as a guest rather than a prisoner, and he is said to have asked Romanos what he would do if their positions were reversed. Romanos reportedly replied that he would have him killed. Alp Arslan reportedly laughed and said: “Do not punish me for your own evil deed.”

The two sides agreed to a peace treaty, in which the Byzantines agreed to pay a large ransom for the release of the emperor, to return the Anatolian provinces they had taken, and to provide military assistance to the Seljuks. The treaty was never fully implemented, since the Byzantine government soon repudiated it, but the immediate effect was to give the Seljuks a free hand in Anatolia.

The Loss of Anatolia

The Battle of Manzikert was followed by a rapid collapse of Byzantine control in Anatolia. The Seljuk Turks, who had already established a presence in the region, took advantage of the chaos to expand their territory, and within a few years, most of Anatolia was under Turkish control. The Byzantine government was unable to organize an effective resistance, since the army had been destroyed at Manzikert and the empire was plagued by civil wars and political instability.

The loss of Anatolia was a catastrophe for the Byzantine Empire. The empire lost its recruiting ground, its economic heartland, and much of its tax base. The Anatolian aristocracy, which had been the backbone of the Byzantine military, was largely destroyed or dispersed, and the empire was forced to rely increasingly on mercenaries from the West, including the Normans, the Germans, and the Turks.

The Internal Crisis

The Battle of Manzikert was followed by a period of internal crisis in the Byzantine Empire, with a series of emperors, civil wars, and political instability. The emperor Romanos IV, who was released by the Seljuks, was soon overthrown by his rival, John Doukas, who blinded him and seized the throne. The blinded emperor, who had led the army at Manzikert, was eventually forced into exile, where he died.

The period after Manzikert saw the rise of powerful noble families in the provinces, especially in the Balkans, who were able to challenge the imperial authority. The most powerful of these families was the Doukas family, which would produce several emperors in the next two centuries. The internal instability, combined with the external pressure, made it impossible for the empire to recover from the loss of Anatolia, and the empire was forced to rely increasingly on Western military assistance, including the Crusader armies, to defend itself.

The Long-Term Consequences

The Decline of Byzantium

The Battle of Manzikert marked the beginning of the long decline of the Byzantine Empire. The loss of Anatolia was a wound that would never heal, and the empire would never again control the Anatolian plateau. The Byzantine emperors of the Comnenian and Palaiologan periods would attempt to recover the lost territory, but they would never succeed, and the empire would gradually be reduced to a small Balkan state.

The Battle of Manzikert also marked a shift in the balance of power in the Mediterranean. Before 1071, the Byzantine Empire was the major power in the eastern Mediterranean, with the Seljuk Turks a distant threat. After 1071, the Seljuk Turks and their successors, the Ottomans, would become the dominant power in the region, and they would eventually absorb the Byzantine state itself.

The Rise of the Turks

The Seljuk victory at Manzikert opened the way for the Turkish settlement of Anatolia, which would transform the region from a Greek-speaking, Christian land into a Turkish-speaking, Muslim land. The Turkish tribes of Central Asia, who had been migrating into the Middle East for centuries, were now able to settle in Anatolia, and the process of Turkification, which would take several centuries, had begun.

The Seljuk state of Rum, founded in 1077, was the first major Turkish state in Anatolia, and it would be the dominant power in the region for the next two centuries. The Seljuk state was eventually replaced by a series of smaller Turkish beyliks, including the Ottoman beylik, which would eventually grow into the Ottoman Empire, the most powerful state in the eastern Mediterranean.

Conclusion

The Battle of Manzikert was one of the most consequential military defeats in medieval history. The battle and its aftermath led to the loss of Anatolia, the empire’s recruiting ground and economic heartland, and it began a long process of decline that would eventually lead to the fall of Constantinople in 1453. The battle marked the beginning of the rise of the Turkish power in the eastern Mediterranean, and it transformed the region from a Greek-speaking, Christian land into a Turkish-speaking, Muslim land.
