The Ottoman dynasty, made up of the members of the House of Osman , ruled the Ottoman Empire from 1299 to 1922, beginning with Osman I (not counting his father, Ertugrul), though the dynasty was not proclaimed until Orhan Bey declared himself sultan. Before that the tribe/dynasty was known as Sögüt Beylik or Beys but was renamed Osmanli (Ottoman in English) in honour of Osman.
