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".
Sunni Islam
The fall of the Ottoman, the biggest Sunni empire in the world for six centuries, the mightiest power in the Mediterranean world and one of the important participants in World War I which joined the war on the side of the Central Powers, bringing caliphate to an end was an epochal event. This resulted in Sunni protests in far off places including the Khilafat Movement in India, which was later on upon gaining independence from Britain divided into Sunni dominated Pakistan and secular India. Pakistan, the most populous Sunni state at its birth, however later got partitioned into Pakistan and Bangladesh. The demise of Ottoman caliphate also resulted in the emergence of Saudi Arabia, a dynastic absolute monarchy with the support of the British and Muhammad ibn Abd al-Wahhab, the founder of Wahhabism. This was followed by a considerable rise in Wahhabism, Salafism and Jihadism under the influence of the preaching of Ibn Taymiyyah a follower of Ahmad bin Hanbal.The expediencies of cold war resulted in encouragement of Afghan refugees in Pakistan to be radicalised, trained and armed to fight the communist regime backed by USSR forces in Afghanistan giving birth to Taliban. The Taliban wrestled power from the communists in Afghanistan and formed a government under the leadership of Mohammed Omar, who was addressed as the Emir of the faithful, an honorific way of addressing the caliph. The Taliban regime was recognised by Pakistan and Saudi Arabia till after 9/11 perpetrated by Osama bin Laden a Saudi national by birth harboured by the Taliban took place, resulting in a war on terror launched against the Taliban.
