The Role of Eyup Sultan in the Conquest of Istanbul: Spiritual Motivation

The conquest of Istanbul in 1453 is one of the turning points of world history. In this great event, the Eyüpsultan district played a critical role both strategically and spiritually. The presence of Abu Ayyub al-Ansari's grave here transformed the conquest from merely a military victory into the fulfillment of a spiritual glad tiding.

Abu Ayyub al-Ansari and the First Siege (669)

Khalid ibn Zayd Abu Ayyub al-Ansari was the great companion who hosted the Prophet (pbuh) in his home during the Hijra to Medina. This valiant companion, who spent his life on battlefields for the spread of Islam, participated in the siege of Istanbul in 669 despite his old age.

Abu Ayyub fell ill during the siege and passed away near the walls of Istanbul. In accordance with his will, he was buried at the most forward point possible near the walls. Behind this will lay the Prophet's glad tiding that Istanbul would surely be conquered.

For centuries, the Byzantines knew the location of Abu Ayyub's grave and showed respect toward it. It is narrated that rain prayers were held at the grave during times of drought.

Fatih's Siege Plan and the Golden Horn

Fatih Sultan Mehmed placed the Golden Horn at the center of his strategic calculations when planning the siege of Istanbul. Byzantium's strongest defense line was the land walls; however, the walls on the Golden Horn side were weaker.

The chain stretched across the mouth of the Golden Horn blocked the Ottoman fleet from entering. Fatih devised an unprecedented plan, transporting ships overland and lowering them into the Golden Horn. This brilliant plan was the move that changed the fate of the siege.

The route along which the ships were transported overland passed through today's Kasimpasa district. In a single night, dozens of ships were lowered into the Golden Horn on greased logs. When morning came, the Byzantines were shocked to see the Ottoman fleet in the Golden Horn.

Spiritual Motivation

During the siege of Istanbul, the Ottoman army's spiritual motivation was at least as important as its military strength. The hadith of the Prophet (pbuh) regarding the conquest of Istanbul gave the soldiers great enthusiasm and determination.

Akshemseddin provided spiritual support by remaining with the army throughout the siege. His discovery that the grave of Abu Ayyub al-Ansari was located here elevated the soldiers' morale to its peak.

During the difficult days of the siege, when some commanders proposed retreat, Akshemseddin's words 'The city will be conquered' ensured that the determination continued.

May 29, 1453: The Conquest

On Tuesday, May 29, 1453, the general assault began with the morning prayer. Simultaneous attacks were launched from the Golden Horn side, the land walls, and the sea side.

After fierce battles, Ottoman soldiers managed to breach the walls. Ulubatli Hasan's planting of the Ottoman flag on top of the walls became the symbol of the conquest.

When Fatih Sultan Mehmed entered the city, his first act was to go to Hagia Sophia. He opened the city to Islam by performing a prayer of gratitude there. Then he gave the order to search for the grave of Abu Ayyub al-Ansari.

After the Conquest: The Sacred Discovery

Shortly after the conquest, Akshemseddin indicated the location of Abu Ayyub al-Ansari's grave. When excavation was carried out, the grave was found, and Fatih Sultan Mehmed experienced great joy.

Immediately afterward, construction of the tomb over the grave began. The tomb, completed in 1458, along with the adjacent mosque, marked the beginning of Eyüpsultan becoming an Islamic center.

This discovery completed the conquest of Istanbul from a religious perspective. The presence of the Prophet's companion's grave here was seen as evidence that the conquest was a divine decree.

The conquest of Istanbul and the discovery of Eyüp Sultan are two inseparable historical events. Without the conquest, the grave could not have been found; without the grave, Istanbul's spiritual identity would have remained incomplete. Everyone who visits Eyüp Sultan today feels the spirit of 1453 and experiences the depth of this unique place where history and faith converge.
