Osman I or Osman Ghazi (Ottoman Turkish: عثمان غازى, romanized: ʿOsmān Ġāzī; Turkish: I. Osman or Osman Gazi; died 1323/4),[1][3] sometimes transliterated archaically as Othman, was the founder of the Ottoman Empire (first known as the Ottoman Beylik or Emirate). While initially a small Turkoman[6] principality during Osman's lifetime, his descendants transformed into a world empire in the centuries after his death.[7] It existed until shortly after the end of World War I.
