ʿAlī Ḥaydar Pāshā ibn Jābir (; , ʿAlī Ḥaydar Bāshā; April 1866 – 12 May 1935) was an Ottoman politician who served as Emir and Grand Sharif of Mecca from 1916 to 1917 during the Arab Revolt and the First World War.
Life in Istanbul to 1914
ʿAlī Ḥaydar, the son of Sharif ʿAlī Jābir Pāshā, was born in April 1866 in a yalı belonging to his grandfather, Sharif ‘Abd al-Muttalib, formerly Emir of Mecca, in the Kanlıca neighborhood of Istanbul (Constantinople). He was an Arab, a member of the Dhawu Zayd, a clan of the Banu Qatada tribe. In 1879 ‘Abd al-Muttalib was appointed Emir of Mecca for the third time and ʿAlī Ḥaydar was sent as a hostage to Istanbul, where he eventually settled in the Çamlıca Hill district. In 1887 he was made a member of the Council of State with the rank of bala.
ʿAlī Ḥaydar's first wife was Sabiha Hanım, a Turkish woman. With her he had one daughter, Şerife Nimet Hanım, and three sons. Their eldest son was Sharif Damat Muhammed Abdülmecid Beyefendi, educated in Britain, who married the Ottoman princess Rukiye Sultan, a daughter of Şehzade Mehmed Selaheddin, son of Murad V. Their second son, Şerif Muhiddin Targan, became a musician and married Safiye Ayla. Their third son was Şerif Muhammed Emin Bey.
ʿAlī Ḥaydar's second wife was an Irishwoman, Isobel Duncan, who converted to Islam and took the name Fatima. They had two daughters, Şerife Süfeyme Hanım and Şerife Musbah Hanım, and one son, Şerif Faisal Bey. Ḥaydar was widely considered an anglophile before the war; he was also a pan-Islamist with close ties to Indian Muslims. In 1908, he was passed over for the Emirate and it was instead given to Ḥusayn ibn ʿAlī, who was older but belonged to the junior Dhawu Awn clan of the Banu Qatada. Ḥaydar, who was considered a liberal on good terms with the Committee of Union and Progress government, was infuriated.
In Istanbul, he served for many years as the naqib al-ashraf, representative of the Hejazi clans. He served as Minister of Waqfs (charitable endowments) from January 1910 in the cabinet of Grand Vizier Ibrahim Hakki Pasha, but he resigned after some time and was replaced by Mustafa Hayri Bey. He also sat for a time in the Imperial Senate. In 1911 the President of the Senate Mehmed Said Pasha was appointed Grand Vizier. Vice-President of the Senate Ahmed Muhtar Pasha was appointed President and ʿAlī Ḥaydar was appointed Vice-President. Most of his descendants live in Turkey and took the surname Targan after the Surname Law.
Life in Medina during World War I
There were rumours upon the Ottoman entry into the world war (1914) that Ḥusayn ibn ʿAlī would be replaced by Ḥaydar, but nothing happened for two years. On 10 June 1916, Ḥusayn openly rebelled. Within days, the Grand Vizier Said Halim Pasha had invited ʿAlī Ḥaydar by telegram to replace Ḥusayn and the Minister of the Interior, Talaat Pasha, had visited him at his home to confirm the offer. According to his own account, Ḥaydar reminded Said Halim of their families' intertwined history: "The fall of my own family and the rise of the Aoun, to which Ḥusayn belongs, was entirely due to Mohammed Ali. You are his grandson and I am the great-grandson of Sherif Ghalib whom he deposed. Now God has given you the opportunity to rectify and redeem the crime of your grandfather." In June, Ḥaydar's agent in Jeddah, Ahmed el-Hezazi, was arrested and his house looted by orders of Ḥusayn.
