Sharif of Mecca in the context of "Sharifian Caliphate"

Hussein bin Ali al-Hashimi (Arabic: ٱلْحُسَيْن بِن عَلِي ٱلْهَاشِمِي, romanized: al-Ḥusayn bin 'Alī al-Hāshimī pronunciation; 1 May 1854 – 4 June 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 proclaimed himself Caliph after the abolition of the Ottoman Caliphate in 1924 and stayed in power until 1925 when Hejaz was invaded by the Sultanate of Nejd. His Caliphate was opposed by the British and French empires, the Zionists and the Wahhabis alike. However, he received support from a large part of the Muslim population of that time and from Mehmed VI. He is usually considered as the father of modern pan-Arabism.

In 1908, in the aftermath of the Young Turk Revolution, Hussein was appointed Sharif of Mecca by the Ottoman sultan Abdul Hamid II. His relationship with the Ottoman government deteriorated after the Committee of Union and Progress took power, particularly because of their policies of Turkification and persecution of ethnic minorities, including Arabs. In 1916, with the promise of British support for Arab independence, although it is debated as to what extent the British were influential in his choice, he proclaimed the Arab Revolt against the Ottoman Empire, accusing the Committee of Union and Progress of violating tenets of Islam and limiting the power of the sultan-caliph. While his armies, led by his sons, were engaged in fighting the Ottoman and German troops in the Middle East, Hussein supported the Armenians during the Armenian genocide and saved up to 4,000 of them. In the aftermath of World War I, Hussein refused to ratify the Treaty of Versailles, in protest of the Balfour Declaration, a document supporting the Jewish settlers in Palestine, and the establishment of British and French mandates in Syria, Iraq, and Palestine. His sons Faisal and Abdullah were made rulers of Iraq and Transjordan respectively in 1921.

The McMahon–Hussein correspondence is a series of letters that were exchanged during World War I, in which the government of the United Kingdom agreed to recognize Arab independence in a large region after the war in exchange for the Sharif of Mecca launching the Arab Revolt against the Ottoman Empire. The correspondence had a significant influence on Middle Eastern history during and after the war; a dispute over Palestine continued thereafter.

The correspondence is composed of ten letters that were exchanged from July 1915 to March 1916 between Hussein bin Ali, Sharif of Mecca and Lieutenant Colonel Sir Henry McMahon, British High Commissioner to Egypt. Whilst there was some military value in the Arab manpower and local knowledge alongside the British Army, the primary reason for the arrangement was to counteract the Ottoman declaration of jihad ("holy war") against the Allies, and to maintain the support of the 70 million Muslims in British India (particularly those in the Indian Army that had been deployed in all major theatres of the wider war). The area of Arab independence was defined to be "in the limits and boundaries proposed by the Sherif of Mecca" with the exception of "portions of Syria" lying to the west of "the districts of Damascus, Homs, Hama and Aleppo"; conflicting interpretations of this description were to cause great controversy in subsequent years. One particular dispute, which continues to the present, is the extent of the coastal exclusion.

Abdullah I (Abdullah bin Hussein; 2 February 1882 – 20 July 1951) was the ruler of Jordan from 11 April 1921 until his assassination in 1951. He was the Emir of Transjordan, a British protectorate, until 25 May 1946, after which he was king of an independent Jordan. As a member of the Hashemite dynasty, the royal family of Jordan since 1921, Abdullah was a 38th-generation direct descendant of Muhammad.

Born in Mecca, Hejaz, Ottoman Empire, Abdullah was the second of four sons of Hussein bin Ali, Sharif of Mecca, and his first wife, Abdiyya bint Abdullah. He was educated in Istanbul and Hejaz. From 1909 to 1914, Abdullah sat in the Ottoman legislature, as deputy for Mecca, but allied with Britain during the First World War. During the war, he played a key role in secret negotiations with the United Kingdom that led to the Arab Revolt against Ottoman rule that was led by his father Sharif Hussein. Abdullah personally led guerrilla raids on garrisons.

Sir Vincent Arthur Henry McMahon GCMG GCVO KCIE CSI KStJ (28 November 1862 – 29 December 1949) was a British Indian Army officer and diplomat who served as Foreign Secretary in the Government of India from 1911 to 1915 and as High Commissioner in Egypt from 1915 to 1917. As the Foreign Secretary McMahon conducted the tripartite negotiations between Tibet, China and Britain that led to the Simla Convention. Even though China did not in the end sign the Convention, the agreement governed the British relations with Tibet till 1947. In Egypt, McMahon was best known for the McMahon-Hussein Correspondence with Hussein bin Ali, Sharif of Mecca, and the Declaration to the Seven in response to a memorandum written by seven notable Syrians. After the Sykes-Picot Agreement was published by the Bolshevik Russian government in November 1917, McMahon resigned. He also features prominently in Seven Pillars of Wisdom, T.E. Lawrence's account of the Arab Revolt against the Ottoman Empire during World War I.

The Syrian Arab Kingdom (Arabic: المملكة العربية السورية, al-Mamlakah al-ʿArabiyya al-Sūriya) was an unrecognized monarchy existing briefly in the territory of historical Syria. It was announced on 5 October 1918 as a fully independent Arab constitutional government with the permission of the British Empire. It gained independence as an emirate after the withdrawal of British forces from OETA East on 26 November 1919, and was proclaimed a kingdom on 8 March 1920.

As a kingdom, the state existed for a little over four months, from 8 March to 25 July 1920. During its brief existence, the kingdom was led by Faisal bin Hussein, son of Hussein bin Ali, Sharif of Mecca. Despite its claims over the region of Syria, Faisal's government controlled a limited area and was dependent on Britain, which, along with France, generally opposed the idea of a Greater Syria and refused to recognize the kingdom. After a four-month-long war, the kingdom surrendered to French forces on 25 July 1920.

Abdülmecid II or Abdulmejid II (Ottoman Turkish: عبد المجید ثانی, romanized: ʿAbdü'l-Mecîd-i sânî; Turkish: II. Abdülmecid; 29 May 1868 – 23 August 1944), commonly known as Abdülmecid Efendi, was the last Ottoman caliph, the only caliph of the Republic of Turkey, and head of the Osmanoğlu family from 1926 to 1944. Unlike previous caliphs, he used the title Halîfe-i Müslimîn ("Caliph of the Muslims"), instead of Emîrü'l-Mü'minîn ("Commander of the Faithful").

He was also a relatively famous artist and a Turkish aesthete, interested in art, mainly literature, painting, and music, and ways to promote it in Turkey. After the abolition of the Ottoman caliphate, he was succeeded for several months by Hussein bin Ali, the Sharif and Emir of Mecca and King of the Hejaz, who was mostly recognized in the Arab world.

Faisal I bin Hussein bin Ali al-Hashimi (Arabic: فيصل بن حسين بن علي الهاشمي, romanized: Fayṣal bin Ḥusayn bin ʻAlī al-Hāshimī; 20 May 1885 – 8 September 1933) was a Hejazi statesman who served as the King of Iraq from 23 August 1921 until his death in 1933. A member of the Hashemite family, he was a leader of the Great Arab Revolt during the First World War, and ruled as the unrecognized King of the Arab Kingdom of Syria from March to July 1920 when he was expelled by the French.

The third son of Hussein bin Ali, the Grand Emir and Sharif of Mecca, Faisal was born in Mecca and raised in Istanbul. From 1916 to 1918, with British assistance, he played a major role in the revolt against the Ottoman Empire. He helped set up an Arab government in Syria, based in Damascus, and led the Arab delegation at the Paris Peace Conference in 1919. In 1920, the Syrian National Congress proclaimed Faisal king, rejecting the French claim to a Mandate for Syria. In response, France invaded a few months later, abolished the kingdom and forced him into exile.
