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".
Heraclius I of Kakheti
In 1675, Archil conflicted with the shah's government, abandoned Kakheti and defected to the Ottoman Empire. Prince Nicholas capitalized on the ensuing turmoil, returned for a second time and was proclaimed as King of Kakheti Heraclius (Erekle) I. Earlier, in 1666, shah Suleiman I had succeeded Abbas II on the Iranian Safavid throne. In 1674, Suleiman I asked him to decisively end his stay in Russia, ordered him to Isfahan and promised to confirm him as king if Heraclius apostatized to Islam. The king refused to become Muslim and the shah's subject, citing the oath of allegiance given by his ancestor, Alexander II of Kakheti (r. 1574–1605), to Feodor I of Russia. Hence, he was deprived of the crown, being allowed, however, to settle to Isfahan. Kakheti was subsequently under direct Safavid rule.
