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".
Ottoman–Safavid War (1532–55)
Under the Grand Vizier Rüstem Pasha, Ottomans attempting to defeat the Shah once and for all, Suleiman embarked upon a second campaign in 1548–1549. Again, Tahmasp adopted a scorched earth policy, laying waste to Armenia. Meanwhile, the French king Francis I, enemy of the Habsburgs, and Suleiman the Magnificent were moving forward with a Franco-Ottoman alliance, formalized in 1536, that would counterbalance the Habsburg threat. In 1547, when Suleiman attacked Persia, France sent its ambassador Gabriel de Luetz, to accompany him in his campaign. Gabriel de Luetz gave military advice to Suleiman, as when he advised on artillery placement during the Siege of Van. Suleiman made gains in Tabriz, Persian ruled Armenia, secured a lasting presence in the province of Van in Eastern Anatolia, and took some forts in Georgia.
