Mehmed II - Conquest of Constantinople

Conquest of Constantinople

When Mehmed II ascended the throne in 1451 he devoted himself to strengthening the Ottoman Navy, and in the same year made preparations for the taking of Constantinople. In the narrow Bosporus Straits, the fortress Anadoluhisarı had been built by his great-grandfather Bayezid I on the Asiatic side; Mehmed erected an even stronger fortress called Rumelihisarı on the European side, and thus having complete control of the strait. Having completed his fortresses, Mehmet proceeded to levy a toll on ships passing within reach of their cannon. A Venetian vessel refusing signals to stop was sunk with a single shot and all the surviving sailors beheaded.

In 1453 Mehmed commenced the siege of Constantinople with an army between 80,000 to 200,000 troops and a navy of 320 vessels, though the bulk of them were transports and storeships. The city was now surrounded by sea and land; the fleet at the entrance of the Bosphorus was stretched from shore to shore in the form of a crescent, to intercept or repel any assistance from the sea for the besieged.

In early April, the Siege of Constantinople began. After several failed assaults, the city's walls held off the Turks with great difficulty, even with the use of the new Orban's bombard, a cannon similar to the Dardanelles Gun. The harbor of the Golden Horn was blocked by a boom chain and defended by twenty-eight warships.

On April 22, Mehmed transported his lighter warships overland, around the Genoese colony of Galata and into the Golden Horn's northern shore; eighty galleys were transported from the Bosphorus after paving a little over one-mile route with wood. Thus the Byzantines stretched their troops over a longer portion of the walls. A little over a month later, Constantinople fell on May 29 following a fifty-seven day siege. After this conquest, Mehmed moved the Ottoman capital from Adrianople to Constantinople. On his accession as conqueror of Constantinople, aged 21, Mehmed was reputed fluent in several languages, including Turkish, Arabic, Hebrew, Persian, Greek and Latin.

Reference is made to the prospective conquest of Constantinople in a hadith (a saying attributed to the Prophet Muhammad): "Verily you shall conquer Constantinople. What a wonderful leader will he be, and what a wonderful army will that army be!" Ten years after the conquest of Constantinople Mehmed II visited the site of Troy and boasted that he had avenged the Trojans by having conquered the Greeks (Byzantines).

When Mehmed stepped into the ruins of the Boukoleon, known to the Ottomans and Persians as the Palace of the Caesars, probably built over a thousand years before by Theodosius II, he uttered the famous lines of Persian poetry:

The spider weaves the curtains in the palace of the Caesars;

the owl calls the watches in the towers of Afrasiab.

After the Fall of Constantinople, Mehmed claimed the title of "Caesar" of Rome (Kayser-i Rûm). The claim was not recognized by the Patriarch of Constantinople, or Christian Europe. Mehmed's claim rested with the concept that Constantinople was the seat of the Roman Empire, after the transfer of its capital to Constantinople in 330 AD and the fall of the Western Roman Empire. Mehmed also had a blood lineage to the Byzantine Imperial family; his predecessor, Sultan Orhan I had married a Byzantine princess, and Mehmed may have claimed descent from John Tzelepes Komnenos. He was not the only ruler to claim such a title, as there was the Holy Roman Empire in Western Europe, whose emperor, Frederick III, traced his titular lineage from Charlemagne who obtained the title of Roman Emperor when he was crowned by Pope Leo III in 800 - although never recognized as such by the Byzantine Empire.

The Byzantine historian Doukas, stated that after the conquest of Constantinople, Mehmed II ordered the 14-year old son of the Grand Duke Lucas Notaras brought to him "for his pleasure". When the father refused to deliver his son to such a fate he had them both decapitated on the spot. Another contemporary Greek source, Leonard of Chios, professor of theology and Archbishop of Mytilene, tells the same story in his letter to Pope Nicholas. He describes Mehmed II requesting for the 14 year old handsome youth to be brought "for his pleasure". This story was originally recorded by Doukas, a Byzantine Greek living in Constantinople at the time of the fall of the city, and does not appear in accounts by other Greeks who witnessed the conquest. Some modern scholars believe that this tale is merely one of a long series of attempts to portray Muslims as morally inferior, and point to the story of Saint Pelagius as its probable inspiration.
