Rise of The Ottoman Empire - Under The Leadership of Mehmed II

Under The Leadership of Mehmed II

Further information: the Sultan's personal information Mehmed II

Mehmed II again came to the Ottoman throne following Murad's death in 1451. But by conquering and annexing the emirate of Karamanid (May–June, 1451) and by renewing the peace treaties with Venice (September 10) and Hungary (November 20) Mehmed II proved his skills both on the military and the political front and was soon accepted by the noble class of the Ottoman court.

Older and a good deal wiser, he made capturing Constantinople his first priority, believing that it would solidify his power over the high military and administrative officials who had caused him such problems during his earlier reign. Good reasons underlay his decision. So long as Constantinople remained in Christian hands, his enemies could use it as either a potential base for splitting the empire at its center or as an excuse for the Christian West's continued military efforts. Constantinople's location also made it the natural "middleman" center for both land and sea trade between the eastern Mediterranean and central Asia, possession of which would ensure immense wealth. Just as important, Constantinople was a fabled imperial city, and its capture and possession would bestow untold prestige on its conqueror, who would be seen by Muslims as a hero and by Muslims and Christians alike as a great and powerful emperor.

Mehmed spent two years preparing for his attempt on the Byzantine capital. He built a navy to cut the city off from outside help by sea; he purchased an arsenal of large cannons from the Hungarian gunsmith Urban; he sealed the Bosphorus north of the city by erecting a powerful fortress on its European shore to prevent succor arriving from the Black Sea; and he meticulously concentrated in Thrace every available military unit in his lands. A trade agreement with Venice prevented the Venetians from intervening on behalf of the Byzantines, and the rest of Western Europe unwittingly cooperated with Mehmed's plans by being totally absorbed in internecine wars and political rivalries.
