Hussein, King of Hejaz
Hussein bin Ali al-Hashimi (Arabic: ٱلْحُسَيْن بِن عَلِي ٱلْهَاشِمِي, romanized: al-Ḥusayn bin 'Alī al-Hāshimī ; 1 May 1853 – 4 July 1931) was a Hejazi leader from the Banu Qatadah branch of the Banu Hashim clan who was the Sharif and Emir of Mecca from 1908 and, after proclaiming the Great Arab Revolt against the Ottoman Empire, King of the Hejaz, even if he refused this title, from 1916 to 1924. He accepted the Caliphate after delegations from the Hejaz and neighboring regions urged him to assume it, staying in power until 1925 when Hejaz was invaded by the Sultanate of Nejd.
