What happened
Between Mehmed II's conquest of Constantinople and the early 20th century, the Ottoman state Osman I had founded grew into one of history's largest and longest-lived empires. Under Suleiman I, who died in 1566, the Ottoman Empire was a genuine world power controlling most of the great cities of Islam alongside large parts of southeastern Europe, ruled the strongest military of its time, and pushed as far as the gates of Vienna. Decline set in gradually rather than suddenly: a naval defeat at Lepanto in 1571 cost the empire its military prestige, a second failed siege of Vienna in 1683 marked a further turning point, and over the following two centuries the empire lost the Balkans, the Crimea, Egypt, and its North African holdings while falling into growing financial dependence on European creditors.
Why it matters
This four-and-a-half-century span, from an Anatolian frontier state to a Mediterranean and Balkan superpower and back down to the sick man of Europe, is the Ottoman Empire's own long story, covered in depth in its own timeline rather than retold here. What matters for Turkey's story is what the empire left behind by the early 1900s: a shrinking, indebted, multiethnic state whose next crisis, the Young Turk Revolution of 1908, would set in motion the final chain of events that produced the modern Turkish republic.
How we know
The Ottoman Empire's territorial peak under Suleiman and its subsequent long decline through the 16th to 19th centuries are documented across Ottoman court records, European diplomatic correspondence, and modern historical scholarship synthesized in general reference histories of the empire.
