The Hashemite Kingdom of Hejaz (Arabic: ? , Al-Mamlakah al-?ij?ziyyah Al-H?shimiyyah) was a state in the Hejaz region in the Middle East (modern-day western Saudi Arabia), the western portion of the Arabian Peninsula ruled by the Hashemite dynasty. It achieved national independence in June 1916 after the destruction of the Ottoman Empire by the British Empire during the First World War when the Sharif of Mecca fought in alliance with the British Imperial forces to drive the Ottoman Army from the Arabian Peninsula during the Arab Revolt.
The United Kingdom promised King Ali of Hejaz a single independent Arab state that would include modern day Syria, Iraq, Palestine and Jordan in addition to the Hejaz region. However, at the end of the First World War, the Treaty of Versailles turned Syria into a French protectorate while Iraq, Palestine and Transjordan became British Protectorates. The relations with the British Empire further deteriorated when Zionist Jews were allowed to move to Palestine. The newly independent kingdom had a brief life and then was invaded in 1924 by the neighbouring Sultanate of Nejd under a resurgent House of Saud. Nejd was much stronger and its military more advanced, and Hejaz tried to defend itself during the year-long war. In 1925, the kingdom collapsed and was conquered by Nejd, creating the Kingdom of Hejaz and Nejd.
In 1908, The Young Turks took over the Ottoman Empire and the Sultan was not able to control it, and in 1909 when a counter-coup failed, The Young Turks took over the government and "secularized" the government. Hussein bin Ali, Sharif of Mecca, was appointed by the previous Sultan of the Ottoman Empire and did not favor the Young Turks, his opposition to the empire grew over time, culminating to the Arab Revolt.
In their capacity as Caliphs, the Sultans of the Ottoman Empire would appoint an official known as the Sharif of Mecca. The role went to a member of the Hashemite family, but the Sultans typically promoted Hashemite intra-familial rivalries in their choice, preventing the building of a solid base of power in the Sharif.
With the outbreak of the First World War in 1914, the Sultan, Mehmed V, in his capacity as Caliph, declared a jihad against the Entente powers. The British in particular hoped to co-opt the Sharif as a weighty alternative religious figure backing them in the conflict. The British already had a series of treaties with other Arab leaders in the region and were also fearful that the Hejaz could be used as a base to attack their shipping to and from India.
The Sharif was cautious but, after discovering that the Ottomans planned to remove and possibly murder him, agreed to work with the British if they would support a wider Arab Revolt and the establishment of an independent Arab Kingdom -- the British implied they would. After the Ottomans executed other Arab nationalist leaders in Damascus and Beirut, the Hejaz rose against and soundly defeated them, almost completely expelling them (Medina remaining under Ottoman control throughout).
In June 1916, Hussein bin Ali, Sharif of Mecca, declared himself King of Hejaz as his Sharifian Army participated with other Arab Forces and the British Empire in expelling the Ottomans from the Arabian Peninsula.
...Great Britain, France and Russia agreed to recognize the Sherif as lawful independent ruler of the Hedjaz and to use the title of "King of the Hedjaz" when addressing him, and a note to this effect was handed to him on 10 December 1916.
The British, though, were compromised by their agreement to give the French control of Syria (comprising modern-day Syria and Lebanon) and did not, in Hussein's eyes, honour their commitments. Nevertheless, they did eventually create Hashemite-ruled kingdoms (in protectorate form) in Transjordan and in Iraq, as well as Hejaz. The changing boundaries of the Ottoman Hejaz Vilayet contributed to uncertainties between the neighbouring Hashemite kingdoms, particularly the competing claim with Transjordan over the inclusion of the sanjak of Ma'an, including the cities of Ma'an and Aqaba.
King Hussein refused to ratify the 1919 Treaty of Versailles, and in response to a 1921 British proposal to sign a treaty accepting the Mandate system stated that he could not be expected to "affix his name to a document assigning Palestine to the Zionists and Syria to foreigners." A further British attempt to reach a treaty failed in 1923-24, and negotiations were suspended in March 1924; within six months the British withdrew their support in favour of their central Arabian ally Ibn Saud, who proceeded to conquer Hussein's Kingdom.
The League of Nations Covenant provided for membership to the signatories of the Peace Treaties; the Hejaz was one of three (the other two were the United States and Ecuador) that failed to ratify Versailles.
