Turkey celebrated on Friday the 567th anniversary of the conquest of Istanbul, dubbed as the start of a new era.
Istanbul, an international city, was besieged 28 times throughout history before its conquest in 1453 by Ottoman Sultan Mehmed II.
The 21-year-old ruler was named Mehmed, the Conqueror in recognition of his victory.
In a prophecy about Istanbul's conquest by a Muslim ruler, Prophet Muhammad had said: "Istanbul will surely be conquered; what a good commander is the conqueror, what a good soldier is the conqueror."
On the night of April 21-22, 67 ships of medium and small sizes were moved to the Golden Horn by soldiers and animals through the bed of Kabatas Stream which poured into the Tophane Port.
The first walls of the city were built in 657 B.C. Roman Emperor Septimius Severus (193-211) demolished these walls during the city's invasion and built a wall that ended near Hagia Sophia, including the Sarayburnu and the Sultan Ahmet Square.
During the reign of Constantinus (306-337), the city-from the Marmara coast to the Golden Horn-was surrounded by city walls for the third time.
Istanbul is strategically important
Feridun Emecen, the dean of Istanbul's 29 Mayis University's Faculty of Literature, told Anadolu Agency that Istanbul is at a strategically important point, as the city connects the East and the West.
In terms of religion, the history professor added that Istanbul has great significance for both Muslims and Christians.
"The birth of a new empire came to the agenda with the conquest of Istanbul by Fatih Sultan Mehmed," he said.
"Fatih is the founder of the Ottoman Empire in a way, he did this by conquering Istanbul. Therefore, the conquest, which is a turning point, is of great importance for Turkish history."
For Fahameddin Basar, a deputy rector at Istanbul's Fatih Sultan Mehmet Foundation University, what stood out in this conquest was how the Ottoman army moved ships up a hill and entered the Golden Horn.
"The Byzantines, who saw the Ottoman fleet in the Golden Horn on the morning of April 22, were surprised," Basar said.
"It was never seen before and it was something the Byzantines did not expect," he added.
Basar described Mehmed II as a "very determined, warrior, and well-educated ruler who had deeply studied the failures in previous sieges of Istanbul."
"During the 54-day siege, the young emperor used techniques of warfare that were not used in previous sieges," he added.
For his part, Hanefi Bostan, an assistant professor at Istanbul's Marmara University's History department, dubbed the conquest as "one of the biggest and most important achievements in Turkish and Islamic history".
"Due to its extraordinary effect in world history, [the conquest of Istanbul] ended the Middle Age, the symbol of the darkness and started the beginning of the light, the New Age," he added.
