The Ottoman Empire lasted over 600 years, a remarkable span from its founding around 1299 to its official end in 1922.

Duration

Officially, the empire endured 623 years , starting with Osman I's establishment in 1299 and concluding when the sultanate was abolished on November 1, 1922. This timeline marks one of history's longest-lasting dynasties, outpacing even the Roman Empire in continuous rule.

Founding Era

Osman I, a Turkic tribal leader in northwestern Anatolia, unified local beyliks around 1299 amid the Mongol invasions' chaos. Early sultans like Orhan (r. 1324–1362) crossed into Europe by 1352, capturing Adrianople in 1361, setting the stage for explosive growth.

Peak Expansion (1453–1683)

Mehmed II's 1453 conquest of Constantinople transformed a regional power into a transcontinental giant, renaming it Istanbul as the new capital. Under Suleiman the Magnificent (1520–1566), it spanned three continents, from Hungary to Yemen, blending Islamic caliphate with sophisticated administration.

Phase| Key Dates| Territorial Highlights
---|---|---
Rise| 1299–1453| Anatolia, Balkans entry 5
Golden Age| 1453–1566| Constantinople, Middle East, North Africa 4
Stagnation| 1683–1800| Vienna sieges fail; territorial peak at ~5M sq mi 9
Decline| 1800–1922| Nationalism, WWI loss 7

Decline and Fall

By the 19th century, dubbed the "Sick Man of Europe," internal reforms like the Tanzimat clashed with Balkan revolts and European pressures. World War I alliances with Germany sealed its fate; post-1918 partition led to Mustafa Kemal Atatürk's republic in 1923.

Legacy Perspectives

Historians view it as a multicultural bridge—innovative in millet governance for religious minorities —yet criticized for later authoritarianism. In modern Turkey, it's romanticized as a glorious past; Arab narratives often highlight colonial overtones. Its cuisine, architecture (e.g., Hagia Sophia), and legal codes endure globally.

TL;DR : 623 years (1299–1922), from Anatolian beylik to vast empire, felled by WWI.
