Mehmed I

Mehmed I ( – 26 May 1421), also known as Mehmed Çelebi (, "the noble-born") or Kirişçi (, "lord's son"), was the sultan of the Ottoman Empire from 1413 to 1421. Son of Sultan Bayezid I and his concubine Devlet Hatun, he fought with his brothers over control of the Ottoman realm in the Ottoman Interregnum (1402–1413). Starting from the province of Rûm he managed to bring first Anatolia and then the European territories (Rumelia) under his control, reuniting the Ottoman state by 1413, and ruling it until his death in 1421. Called "The Restorer," he reestablished central authority in Anatolia, and he expanded the Ottoman presence in Europe by the conquest of Wallachia in 1415. Venice destroyed his fleet off Gallipoli in 1416 as the Ottomans lost a naval war. Provided by Wikipedia
