The Battle of Manzikert ended with Sultan Muhammad Alp Arslan, the second ruler of the Great Seljuk Empire, defeating the Byzantine army commanded by Romanos Diogenes on August 26, 1071. Byzantine Emperor Romanos Diogenes was captured after the battle.
The road to the battle
Sultan Alp Arslan, who was born to Çağrı Bey, the governor of Khorasan, and his last wife, first captured the cities of Kars and Ani during his reign. The Seljuks thereby acquired their first territories from Byzantium.
After the Abbasid caliph requested assistance in 1070, Sultan Alp Arslan set out with his army to march against the Fatimids. Having learned that Alp Arslan would go to Egypt, the Byzantine army began its campaign in the east.
When he learned that the Byzantine army was advancing, Sultan Alp Arslan turned back and headed toward the Syrian frontier. After creating the impression that he would be stationed in the city of Ray, Alp Arslan advanced toward Muş and established his camp on the Manzikert Plain.
Victory at Manzikert
On Friday, August 26, 1071, Sultan Alp Arslan led his army in prayer and prayed. The Seljuk army then advanced against the Byzantine forces commanded by Romanos Diogenes.
The Seljuks used the “Turan” tactic in the battle. The Seljuk army inflicted a heavy defeat on the Byzantine army, which was described as being far larger in number, and captured Romanos Diogenes.
Prof. Dr. Mustafa Alican, rector of Muş Alparslan University and a specialist in medieval history, said the Battle of Manzikert was one of the developments that changed world history. Alican said that following the battle, the Turks assumed a leading position in the Islamic world and that the Muslims’ advance westward accelerated.
Alican said that Muslims led by the Turks reached as far as western Anatolia within 10 years of the battle. The Turks conquered İznik in the second half of the 1070s and established a new Seljuk state there.
Impact on the conquest of Anatolia and Istanbul
The victory at Manzikert launched a process that facilitated the conquest of Anatolia. The rapid Turkification and Islamization of Anatolia following the victory was considered one of the major obstacles preventing Byzantium from launching another large-scale offensive in the region comparable to Manzikert.
Alican said Byzantium gradually retreated, losing its territories in Anatolia, and eventually became confined to Istanbul. Alican said this process was connected to the developments that led to Fatih Sultan Mehmet’s conquest of Istanbul in 1453, and conveyed the assessment that the victory at Manzikert initiated the process leading to the conquest of Istanbul.
Military strategy and the captured emperor
Alican said the number of soldiers in the Seljuk army was approximately one-quarter of the number in the Byzantine army. He said Romanos Diogenes had rejected Sultan Alp Arslan’s peace initiatives before the battle and believed he would win by relying on his numerical superiority.
Alican said the battle tactic developed by Alp Arslan using the advantage of knowing the region enabled the smaller Seljuk army to defeat the larger Byzantine army, and highlighted the importance of the Turan tactic in the victory. He also noted that the Battle of Manzikert remains important in terms of military strategy and is still taught as a case study.
According to Alican’s account based on historical traditions, Romanos Diogenes was brought to Sultan Alp Arslan’s tent after the battle. The two rulers held talks, and a 50-year agreement was prepared requiring the Byzantine Empire to submit to the Seljuk state, pay an annual tax and send soldiers to Seljuk campaigns.
Alican said the Treaty of Manzikert did not take effect because Romanos Diogenes was deposed and killed following disputes in the Byzantine Palace.
Sultan Alp Arslan’s characteristics
Alican said historical traditions describe Sultan Alp Arslan as broad-built and tall. He said Alp Arslan was known for his justice and compassion and was referred to by the title “Sultan al-Adil,” meaning just ruler.
Alican said Sultan Alp Arslan was characterized as compassionate and merciful toward Muslims, but stern toward non-Muslims and his enemies.
