Fateh Sultan Mehmet – the Conqueror

Preparation for the conquest of Istanbul started only, one year ahead. Huge canons that were necessary for the siege were moulded. In 1452, Rumeli Castle was constructed to control the Bosphorus. A mighty fleet of 16 galleys was formed. The number of soldiers were doubled. The supply routes to Byzantine were taken under control. An agreement was made with Genoese to keep Galata impartial during the war. In Aprıl 1453, the first Ottoman frontier forces were seen in front of Istanbul. The siege was starting. The important points of the conquest are chronologically listed below.

6 April 1453: Sultan Mehmed pitched his imperial tent by• the door of Romanus in
Topkapi. The same day the cìty was besieged from the
Golden Horn to the Marmara Sea from the land.

6-7 April 1453: First cannons fired. Some of thè fortresses in Edirnekapi were destroyed.

9 April 1453: Baltaoğlu Süleyman Bey la unched the first attack to enter the Golden Horn gulf.

9-10 April 1453: Some of the fortresses on Bus were taken. Baltaoğlu Süleyman Bey seized the Marmara Islands.

11 April 1453: The big fortresses were bombarded by cannon fires. Holes and cracks were opened here and there. Serious destruction inflicted by ceaseless bombardment

12 April 1453 The Ottoman fleet attacked the ships protecting the Golden Horn. The victory of the Christian ships decreased the morale of the Ottoman army. At the order of Sultan Mehmed, the Byzantine ships were pounded by mortar fire, and one galley was sunk.

18 April 1453, Night: The Sultan gave his first crucial order. The attack lasted four hours but it was scattered.

20 April 1453: A naval skirmish took place close to Yenikapi between the Ottoman fleet and four Byzantine war-ships with three supply ships full of food and weapons sent by the Papacy The Sultan came to the shore himself and ordered Baltaoğlu Süleyman Pasha to sink those ships by any means possible. The Ottoman fleet could not stop enemy’s ships which were bigger. With this failure the Ottoman army lost its morale and showed the signs of defeat. Ottoman soldiers staned defecting from the army. Soon, the Byzantizne Emperor wanted to take advantage of thís situation and offered peace. The offer, supported by famous Vizier Çandarlı Halil Pasha, was rejected by Sultan Mehmed. The siege and bombardment of the fortresses with cannons continued.

During this chaos and widespread feeling of defeat, a letter from the Sultan’s spiritual teacher Akshemseddin promised good news about the conquest. Encouraged by this spiritual support, Fatih Sultan Mehmed, escalated the attaek, and decided to add an element of surprise: the Ottoman fleet anchored in Dolmabahce would be moved to Gold en Horn gulf land.
22 April 1453: In early. hours of the morning, Byzantine Christians were dumbfounded and horrified when they saw Ottoman galleys moving down on the hills of the bay Seventy ships carried by cows and balanced by hundreds of soldiers via ropes were slid over slipways. By afternoon the ships were inside the well protected bay.

The surprise appearance of the Ottoman fleet in the bay created panic among Byzantine residents of Costantinople. The fonresses on che shore of Golden Horn became a vulnerable spot and some of the Byzantine forces were moved there. This weakened the defence of the land fortresses.

28 April 1453: The attempt to burn the Ottoman ships in the bay was prevented by heavy, cannon fire. A bridge was constructed between Ayvansaray and Sütluce to attack the fortresses located on the shore of the bay An offer of unconditional surrender was delivered to the Emperor through the Genoese. If he surrendered he could have gone wherever he wanted and the life and property of his people would .have been spared. The Emperor rejected thzs offer.

7 May 1453: A three hour long attack was launched on the stream of Bayrampasa with a 30,000 strong force; but it was failed.

12 May 1453: A thunderous attack made towards the point between Tekfursaray and Edirnekapı was defeated by the Byzantine defence.

16 May 1453: When the underground tunnel dug in the direction of Eğrikapı intersected the Byzantinian underground tunnel, an underground skirmish erupted. The same day, an attempt to cut the sturdy chain blocking the entrance of the bay failed. The following day the attack was repeated, but again ended with failure.
18 May 1453: Ottoman forces launched another attack from the direction of Topkapı, by using a wooden mobile tower. the Byzantine burned the tower at night and emptied the trenches that were filled by Ottomans. Over the following days, bombarding of the land fortresses was continued.

25 May 1453: Fatih Sultan Mehmed, sent Isfendiyar Beyoğlu ismail Bey as an ambassador offering him to surrender for the last time. According to this offer, the Emperor and his followers could take their wealth and go anywhere they wished. The people who decided to stay could keep their belongings and estates. This offer too was rejected.

26 May 1453: According to rumors European countries and especially Hungarians were planning to mobilise their troops to help the Byzantines unless the siege was ended. Upon hearing these rumors Sultan Mehmed gathered his war council. In the meeting Çandarlı Halil Pasha and his party defended their previous position, that is, of putting an end to the siege. Sultan Mehmed with his tutor Zağanos Pasha, his teachers Akşemseddin, Molla Gızrani and Molla Hızsrev opposed the idea of quitting. They decided to continue the war and Zağanos Pasha was commissioned for preparations.

27 May 1453: The general attack was announced to the Ottoman army 28 May 1453: The army, spent the day by resting and preparing for the next day’s attack. There was a complete silence among soldiers. Sultan Mehmed inspected the army and encouraged them for the great attack. On the other side, a religious ceremony was held in Haghia Sophia Church. The Emperor urged people to participate in the defence. This would be the Iast Byzantine ceremony.

29 May 1453: Platoons positioned for the assault. Sultan Mehmed gave the order to attack at midnight. Inside Constantinople, while the soldiers positioned for war, people filled rhe churches. The Ottoman army launched its final assault accompanied by commemoration of God and beats of drums. The first assault was performed by infantry and it was followed by Anatolian soldiers. When 300 Anatolian soldiers were martyred, the Janissaries staned their attack. With the presence of Sultan Mehmed, the Ottoman army was motivated and cbest to chest fights started. Meanwhile the young soldier called Ulubatlı Hasan who first erected the Ottoman flag on Byzantine land fortresses was martyred. Upon the entrance of the Janissaries from Belgradkapı and the surrender of the last defenders in Edimekapı front, the Byzantine defence collapsed.

Abandoned by his soldiers, the Emperor was killed during street skirmishes. Turkish forces entered from every direction and crushed the Byzantine defence completely Towards noon Sultan Mehmed entered the city He went directly to Haghia Sophia Church and convened it to mosque.



The conquest of Istanbul has had such a historical impact on the Turkish and Muslim world to the degree that some historians demarcate the end of the Middle Ages with the city’s conquest. With the siege of Istanbul, the Ottomans proceeded to establish hegemony over numerous independent Turkish states (Beylik) within Anatolia (Asia Minor). The result of imperial conquest was to unify the Turkish populations in Anatolia. In tum, other non-Turkish, Muslim communities and principalities were brought together under the aegis of Ottoman leadership so that the Ottoman Beylik would eventually expand into an Empire.

After the conquest, Ottoman Muslims were to take dynamic roles in shaping international politics. Up until that point, European

Chrìstendom had, for three centuries, striven to evict Muslims from Asia Minor, with Istanbul functioning as a border station for the Crusaders. After the conquest, however, the sovereignty of Asia Minor Muslims was assured, and they were no longer threatened by the Crusaders. Indeed Muslims would eventually begin European campaigns, so that the conquest of Istanbul became a historic turning point vis a vis proving superiority over Europe. A second critical component in Istanbul’s signiEicance to world events and history is its relationship to the Renaissance. After its conquest, many Byzantine artists and philosophers emigrated to European centers-mostly Rome taking with them valuable manuscripts regarding advanced ıntellectual developments. These intelligentsia were instrumental in the movement to revive and revise classical Greek culture. The clash and reunification of the two divergent schools sparked the ideological revolution known as the European Renaissance, and Byzantine intellectuals from Istanbul were pivotal agents in catalysıng the movement.



The seventh Ottoman Sultan, Sultan Mehmed, the conquerror acceded to the throne twice-in 1444 and 1451-reigning for a total of 31 years.

In his youth, Prince Mehmed received a privileged edu cation, trained by the most pre-eminent scholars of his time. Among them Molla Yegan, Akşemseddin, Molla Gürani, and Molla Ayas. In accordance with the royal tradition, in order to provide him the experience required for ruling the entire state, he was appointed governor of Manisa. Concomitantly, he was schooled in the fields of mathematics, geometry, textual analysis of the Quran, religious jurisprudence, theological philosophy, and history He learned Arabic, Persian, Latin, Greek, and the Serbian languages.
Prince Mehm.d was preened to become a powerful military leader as well as an opézi-minded intellectual. Indeed, his ınvolvement in literature placed him in the class of master in the class of master poets of his time: he designated the pen name “Avni” to sign hís poems, for which he was renowned and respected by the intelligentsia of the literary cadre. The first royal collection of poems (Divan) is his. While the adolescent prince Mehmed was governor of Manisa, his father, Sultan Murad II, decided to retire, declaring his son Sultan.

Because of the perception that the office would be. vulnerable with a boy-king, European states began organising campaigns along the Ottoman borders, coalescing as the Crusade to evict the Ottomans from Europe Declaring himself chief commander of the Ottoman army, Sultan Murad II fought a decisive and bloody battle at Varna and defeated the Crusaders. With the victory Sultan Murad II reassumed executive leadership, sending prince Mehmed back to Manisa to continue his rigorous training. With the death of his father, Sultan Mehmed came to the capital city of Edirne in order to accede a second time to the throne. His very first pruject as Sultan was to fulfill his dream of conquering Istanbul-a plan that had engaged him during his stint at Manisa. His strategy was as follows. First, he erected a fortress known as Rumeli Castle, across from the Anatolia Castle, on the European side of Istanbul. He had been stockpiling an entire fleet of gigantic canons from various European states, and once sufficiently equipped, he decided he would lead the army himself on the day of attack. After succeeding in the conquest of Istanbul, he turned to expanding control of European lands to the River Danube, and took on the matter of the Serbian problem. Regarding the latter, he managed to convince the Serbs to accept Ottoman domination. He continued with assaults on Genoese lands and conquered Amasra, an important military base, and Kefe, a commercial port. He set his sights on the two capital cities on the Black Sea: he ended the Çandaroğulları rule by taking Sinop; the Pontus rule ended once he conquered Trabzon. He proceeded to add the Midilli Island as part of Ottoman land, completed the conquest of Bosnia Herzeg,ovina, and united the Balkans south of the River Danube.

By taking the Karaman, capital of Konya and the important city of Karaman, Sultan Mehmed, the Conqueror established Karaman Cıunty From the Venetians, he seized the Eğriboz island; he ended the Beylik rule in Alaiye (Alanya) district. After defeating Uzun Hasan, the Shah of Akkoyunlu in the Battle of Otlukbeli, he had firmly established what was an incontestable Ottoman domination in Anatolia. Later, he set his sights to the West, capturing several Genoese castles and affixíng the Crimea Khanate to the Ottoman Empire. Once Albania-and later, Taranto in southern Italy-succumbed to Ottoman control, the Papacy panicked. The. Pope called for another Crusade; however, European states knew they could ill afford the risk. Mobilising for another battle, Sultan Mehmed the conquerror oisoned.



Mehmed II, referred to as Fatih or “the Conqueror,” was responsible for the Ottoman state’s development into a true imperial power after having accomplished the great feat of conquering Constantinople in 1453. This Ottoman Sultan had received a most rigorous education, not only in the Islamic ans and sciences but also in the western tradition, and thus was well trained as the future imperial ruler of the Ottoman Empire. As a military commander, he possessed extraordinary talent, managing an exceedingly disciplined and well-organised army He was renowned for the complete secrecy with which he guarded all military tactics and campaigns, divulging nothing, even to his closest cohorts. He was the first Ottoman Sultan to pay substantive attention to artillery

Before Sultan Mehmed the conquerror, canon were deployed solely as a means to frighten the enemy by virtue of their thunderous booms; in other words, their destructive power and the critical role they would assume in warfare went entirely unacknowledged. Realising their perspective power, Sultan
Mehmed the conquerror,, ordered his engineers to produce larger canons, in quantities which were, at that point, far unsurpassed. He is reported to ha..e computed the ballistic and resistance calculations on his own, single-handedly. He aspired to nothing less than a world wide empire, and spent the entirety of his adult life in pursuit of this goal. Within 30 years of his reign, he had conquered 17 states, including two empires. He transformed The Black Sea into a “Turkish lake.” He conquered the entire Balkan region and the islands of the Aegean. The kingdom he had inherited from his father, Sultan Murad II, had increased in land mass some 2.5 times under Fatih. In addition to his imperial conquests, Sultan Tlehmed the conquerror occupies an important place in Ottoman history• for various state-level structural and political reforms. He overhauled and reconstrueted the entire administrative, financial, and juridical syfstenis. An open-minded and broadly-educated ruler, he encouraged the flourishment of cultural and artistic expression as well as demonstrated a rare tolerance for religious freedom. For example, after seizing the Byzantine city, Fatih convened a coterie of Italian humanists and scientists in the palace and became a great protector of Orthodox Christianity In addition, he created the rank of Orthodox Patriarch on a level equal to that of vizier or inister of the state. He requested Gennadios, the Second Patriarch, to produce a book explaining the principles of the Christian faith and had it translated into Ottiıman Turkish. For ages thereafter, the university he establishe d in the environs of the Fatih Mosque served as a central institute fıır the furtherance of Islamic research and education. On occasion, the Conquerror would consult prominent Muslim thïnkers (ulama) on current theological positions. As a result of his patronage of the sciences of the time, mathematics, astronomy and theology reached their respective apogees during his reign.
