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".
Selim I
Selim I wanted to use the Ottoman Empire's central location to completely cut the ties between Shah Ismail's Safavid Empire and the rest of the world. Even though the raw materials for important Ottoman silk production at that time came from Persia rather than developed within the Ottoman Empire itself, he imposed a strict embargo on Iranian silk in an attempt to collapse their economy. For a short amount of time, the silk resources were imported via the Mamluk territory of Aleppo, but by 1517, Selim I had conquered the Mamluk state and the trade fully came to a standstill. So strict was this embargo that, "merchants who had been incautious enough not to immediately leave Ottoman territory when war was declared had their goods taken away and were imprisoned," and to emphasize frontier security, sancaks along the border between the two empires were given exclusively to Sunnis and those who did not have any relationship with the Safavid-sympathizing Kızılbaş. Iranian merchants were barred from entering the borders of the Ottoman Empire under Selim I. Shah Ismail received revenue via customs duties, therefore after the war to demonstrate his commitment to their thorny rivalry, Selim I halted trade with the Safavids—even at the expense of his empire's own silk industry and citizens.
