The Ottoman Empire
The Ottoman Empire was one of the largest and longest-lasting empires in history, founded around 1299 and eventually spanning southeastern Europe, the Middle East, and North Africa before its dissolution after World War I.
Founded by Osman I in northwestern Anatolia, the empire expanded steadily over centuries, capturing Constantinople in 1453 under Sultan Mehmed II and ending the Byzantine Empire, renaming the city Istanbul as its new capital.
At its height in the 16th and 17th centuries, the empire controlled vast territories across three continents, becoming a major center of trade, culture, and Islamic scholarship under rulers such as Suleiman the Magnificent.
The empire gradually declined over the following centuries and was formally dissolved after World War I, with modern Turkey emerging from its remnants under Mustafa Kemal Atatürk in 1923.
