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".
History of Islam
In the early 16th century, the Shi'ite Safavid dynasty assumed control in Persia under the leadership of Shah Ismail I, defeating the ruling Turcoman federation Aq Qoyunlu (also called the "White Sheep Turkomans") in 1501. The Ottoman sultan Selim I sought to repel Safavid expansion, challenging and defeating them at the Battle of Chaldiran in 1514. Selim I also deposed the ruling Mamluks in Egypt, absorbing their territories in 1517. Suleiman I (also known as "Suleiman the Magnificent"), Selim I's successor, took advantage of the diversion of Safavid focus to the Uzbeks on the eastern frontier and recaptured Baghdad, which had fallen under Safavid control. Despite this, Safavid power remained substantial, rivalling the Ottomans. Suleiman I advanced deep into Hungary following the Battle of Mohács in 1526 — reaching as far as the gates of Vienna thereafter, and signed a Franco-Ottoman alliance with Francis I of France against Charles V of the Holy Roman Empire 10 years later. While Suleiman I's rule (1520–1566) is often identified as the apex of Ottoman power, the empire continued to remain powerful and influential until a relative fall in its military strength in the second half of the eighteenth century.
