Paul Kennedy on Istanbul

“The Ottoman Empire was, of course, much more than a military machine. A conquering elite (like the Manchus in China), the Ottomans had established a unity of official faith, culture, and language over an area greater than the Roman Empire, and over vast numbers of subject peoples. For centuries before 1500 the world of Islam had been culturally and technologically ahead of Europe. Its cities were large, well-lit, and drained, and some of them possessed universities and libraries and stunningly beautiful mosques. In mathematics, cartography, medicine, and many other aspects of science and industry—in mills, gun-casting, lighthouses, horsebreeding—the Muslims had enjoyed a lead. The Ottoman system of recruiting future janissaries from Christian youth in the Balkans had produced a dedicated, uniform corps of troops. Tolerance of other races had brought many a talented Greek, Jew, and Gentile into the sultan’s service—a Hungarian was Mehmet’s chief gun-caster in the Siege of Constantinople. Under a successful leader like Suleiman I, a strong bureaucracy supervised fourteen million subjects—this at a time when Spain had five million and England a mere two and a half million inhabitants. Constantinople in its heyday was bigger than any European city, possessing over 500,000 inhabitants in 1600.”

“Would all of Europe soon go the way of northern India? By 1529, with the Turks besieging Vienna, this must have appeared a distinct possibility to some. In actual fact, the line then stabilized in northern Hungary and the Holy Roman Empire was preserved; but thereafter the Turks presented a constant danger and exerted a military pressure which could never be fully ignored. Even as late as 1683, they were again besieging Vienna. Almost as alarming, in many ways, was the expansion of Ottoman naval power. Like Kublai Khan in China, the Turks had developed a navy only in order to reduce a seagirt enemy fortress—in this case, Constantinople, which Sultan Mehmet blockaded with large galleys and hundreds of smaller craft to assist the assault of 1453. Thereafter, formidable galley fleets were used in operations across the Black Sea, in the southward push toward Syria and Egypt, and in a whole series of clashes with Venice for control of the Aegean islands, Rhodes, Crete, and Cyprus. For some decades of the early sixteenth century Ottoman sea power was kept at arm’s length by Venetian, Genoese, and Habsburg fleets; but by midcentury, Muslim naval forces were active all the way along the North African coast, were raiding ports in Italy, Spain, and the Balearics, and finally managed to take Cyprus in 1570–1571, before being checked at the battle of Lepanto.”
