Suleiman the Magnificent
At the time of Suleiman's death, the Ottoman Empire was one of the world's foremost powers. Suleiman's conquests had brought under the control of the Empire major Muslim cities (such as Baghdad), many Balkan provinces (reaching present day Croatia and Hungary), and most of North Africa. His expansion into Europe had given the Ottoman Turks a powerful presence in the European balance of power. Indeed, such was the perceived threat of the Ottoman Empire under the reign of Suleiman that Austria's ambassador Busbecq warned of Europe's imminent conquest: "On [the Turks'] side are the resources of a mighty empire, strength unimpaired, habituation to victory, endurance of toil, unity, discipline, frugality and watchfulness ... Can we doubt what the result will be? ... When the Turks have settled with Persia, they will fly at our throats supported by the might of the whole East; how unprepared we are I dare not say." Suleiman's legacy was not, however, merely in the military field. The French traveler Jean de Thévenot bears witness a century later to the "strong agricultural base of the country, the well being of the peasantry, the abundance of staple foods and the pre-eminence of organization in Suleiman's government".
List of campaigns of Suleiman the Magnificent
In 1520, Suleiman became the Sultan at the age of 25, succeeding his father Selim I (who had himself more than doubled the size of the Empire through his own campaigns), and began a series of military conquests. In addition to campaigns led by his viziers and admirals, Suleiman personally led 13 campaigns. The total duration of these campaigns was ten years and three months. The details of the first eight campaigns were preserved in Suleiman's diary. His main opponents were Ferdinand I from the House of Habsburg (later the Holy Roman Emperor), and Tahmasp I of Safavid Persia. Most of Suleiman's campaigns were directed to the west. In 1521 the Ottomans captured Belgrade, which had been besieged unsuccessfully by Mehmed the Conqueror, and in 1526 the Battle of Mohács ended with the defeat of Louis II of Hungary. But Suleiman did not annex most of Hungary till 1541. In 1529 Suleiman's conquests were checked at the siege of Vienna. Although from 1529 to 1566 the borders of the Ottoman Empire moved further west, none of the later campaigns achieved the decisive victory that would secure the new Ottoman possessions. He annexed most of the Middle East in his conflict with the Safavids. Under Suleiman's rule, the Ottoman annexed large swathes of North Africa as far west as Algeria, while the Ottoman fleet dominated the seas from the Mediterranean to the Red Sea and the Persian Gulf.
