The Great Ottoman Empire or Turkish Empire or Sublime Ottoman State was a Turkish empire which lasted from 27 July 1299 to 1 November 1922 (623 years); when the Sultanate was abolished.

The Ottoman Empire was one of the largest and longest lasting empires in history; such that the Ottoman State; its politics; conflicts; and cultural heritage in a vast geography provide one of the longest continuous narratives. During the 16th and 17th centuries; in particular at the height of its power under the reign of Suleiman the Magnificent; the empire was one of the most powerful states in the world - a multinational; multilingual empire that stretched from the southern borders of the Holy Roman Empire to the outskirts of Vienna; Royal Hungary (modern Slovakia) and the Polish-Lithuanian Commonwealth in the north to Yemen and Eritrea in the south; from Algeria in the west to Azerbaijan in the east; controlling much of southeast Europe; Western Asia and North Africa.

With Constantinople as its capital and vast control of lands around the Mediterranean basin; the empire was at the center of interactions between the Eastern and Western worlds for over six centuries.
