1566 – 1839Wars & Stagnation (1566–1839)The period from Suleiman's death to the Tanzimat reforms spans 273 years of gradual but accelerating decline punctuated by moments of recovery. The failed siege of Vienna (1683) marks the definitive end of Ottoman expansion in Europe; the Treaty of Karlowitz (1699) begins the long territorial retreat. Russia emerges as the empire's most dangerous enemy, fighting six wars and pushing the Ottoman frontier steadily south. The Janissaries -- once the empire's elite force -- become a conservative political force that murders reforming sultans. The empire earns its 19th-century epithet: 'the sick man of Europe.'

1839 – 1922Reform & Collapse (1839–1922)The final 83 years of Ottoman history are the most dramatic -- a race between modernisation and disintegration that the empire ultimately loses.
