The sultans of the Ottoman Empire , made up solely of the members of the Ottoman dynasty (House of Osman), ruled over the transcontinental empire from its inception in 1299 to its dissolution in 1922. At its height, the Ottoman Empire spanned from Hungary in the north to Somalia in the south, and from Algeria in the west to Iran in the east. Administered at first from the city of Bursa, the empire's capital was moved to Edirne in 1363 following its conquest by Murad I, and then to Constantinople (present-day Istanbul) in 1453 following its conquest by Mehmed II.
