Kingdom of Hejaz in the context of "Ottoman Army (1861–1922)"

The Khedivate of Egypt (Arabic: الْخُدَيْوِيَّةُ الْمِصْرِيَّةُ or خُدَيْوِيَّةُ مِصْرَ, Egyptian Arabic pronunciation: [xedeˈwejjet mɑsˤɾ]; Ottoman Turkish: خدیویت مصر Hıdiviyet-i Mısır) was an autonomous tributary state of the Ottoman Empire established and ruled by the Muhammad Ali Dynasty following the defeat and expulsion of Napoleon Bonaparte's forces, ending the short-lived French occupation of Lower Egypt. The Khedivate of Egypt had also expanded to control present-day Sudan, South Sudan, Eritrea, Djibouti, northwestern Somalia, northeastern Ethiopia, Lebanon, Jordan, Israel, Palestine, Syria, Greece, Cyprus, southern and central Turkey, in addition to parts from Libya, Chad, Central African Republic, Democratic Republic of Congo, and Uganda, as well as northwestern Saudi Arabia, parts of Yemen and the Kingdom of Hejaz.

The United Kingdom invaded and took control in 1882. In 1914, the Ottoman Empire connection was ended and Britain established a protectorate called the Sultanate of Egypt.

The Arab Revolt (Arabic: الثورة العربية al-Thawra al-'Arabiyya), also known as the Great Arab Revolt (الثورة العربية الكبرى al-Thawra al-'Arabiyya al-Kubrā), was an armed uprising by the Hashemite-led Arabs of the Hejaz against the Ottoman Empire amidst the Middle Eastern theatre of World War I.

On the basis of the McMahon–Hussein Correspondence, exchanged between Henry McMahon of the United Kingdom and Hussein bin Ali of the Kingdom of Hejaz, the rebellion against the ruling Turks was officially initiated at Mecca on 10 June 1916. The primary goal of the Arab rebels was to establish an independent and unified Arab state stretching from Aleppo to Aden, which the British government had promised to recognize.

The partition of the Ottoman Empire (30 October 1918 – 1 November 1922) was a geopolitical event that occurred after World War I and the occupation of Constantinople by British, French, and Italian troops in November 1918. The partitioning was planned in several agreements made by the Allied Powers early in the course of World War I, notably the Sykes–Picot Agreement, after the Ottoman Empire had joined Germany to form the Ottoman–German alliance. The huge conglomeration of territories and peoples that formerly comprised the Ottoman Empire was divided into several new states. The Ottoman Empire had been the leading Islamic state in geopolitical, cultural, and ideological terms. The partitioning of the Ottoman Empire after the war led to the domination of the Middle East by Western powers such as Britain and France, and saw the creation of the modern Arab world and the Republic of Turkey. Resistance to the influence of these powers came from the Turkish National Movement but did not become widespread in the other post-Ottoman states until the period of rapid decolonization after World War II.

The League of Nations mandate granted the French Mandate for Syria and the Lebanon, the British Mandate for Mesopotamia (later Iraq) and the British Mandate for Palestine, later divided into Mandatory Palestine and the Emirate of Transjordan (1921–1946). The Ottoman Empire's possessions in the Arabian Peninsula became the Kingdom of Hejaz, which the Sultanate of Nejd (today Saudi Arabia) was allowed to annex, and the Mutawakkilite Kingdom of Yemen. The Empire's possessions on the western shores of the Persian Gulf were variously annexed by Saudi Arabia (al-Ahsa and Qatif), or remained British protectorates (Kuwait, Bahrain, and Qatar) and became the Arab States of the Persian Gulf.

The Sultanate of Nejd (Arabic: سلطنة نجد, Salṭanat Najd) was the third iteration of the Third Saudi State, from 1921 to 1926. It was a monarchy led by the House of Saud, and a legal predecessor of modern-day Saudi Arabia. This version of the Third Saudi State was created when Abdulaziz ibn Saud, Emir of Riyadh, declared himself sultan over Nejd and its dependencies. On the 2nd of December 1922, the Nejd signed an agreement with Kuwait defining their border with each other. The border would be a straight line along the 29th parallel. In December 1925, the Kingdom of Hejaz surrendered to the forces of ibn Saud, who was thereafter proclaimed king of the Hejaz in January 1926 and merged his dominions into the Kingdom of Hejaz and Nejd.

The Hashemites (Arabic: الهاشميون, romanized: al-Hāshimiyyūn), officially the House of Hashim, are the royal family of Jordan, which they have ruled since 1921, and were the royal family of the kingdoms of Hejaz (1916–1925), Syria (1920), and Iraq (1921–1958). The family had ruled the city of Mecca continuously from the 10th century, frequently as vassals of outside powers, and ruled the thrones of the Hejaz, Syria, Iraq, and Jordan following their World War I alliance with the British Empire.

The family belongs to the Dhawu Awn, one of the branches of the Ḥasanid Sharifs of Mecca, also referred to as Hashemites. Their eponymous ancestor is traditionally considered to be Hashim ibn Abd Manaf, great-grandfather of the Islamic prophet Muhammad. Another claimed ancestor is Ali ibn Abi Talib, the usurped successor of the prophet Muhammad according to Shia Islam. The Ḥasanid Sharifs of Mecca (from whom the Hashemite royal family is directly descended), including the Hashemites' ancestor Qatadah ibn Idris, were Zaydī Shīʿas until the late Mamluk or early Ottoman period, when they became followers of the Shāfiʿī school of Sunnī Islam.

The Banu Qatadah (Arabic: بنو قتادة, romanized: Banū Qatādah, lit. 'Sons of Qatadah'), or the Qatadids (Arabic: القتاديون, romanized: al-Qatādayūn), were a dynasty of Hasanid sharifs that held the Sharifate of Mecca continuously from 1201 until its abolition in 1925. The Qatadids were the last of four dynasties of Hasanid sharifs (preceded by the Jafarids/Musawids, Sulaymanids, and the Hawashim) that all together ruled Mecca since about the mid-10th century. The progenitor of the dynasty was Qatadah ibn Idris, who took possession of the holy city from the Hawashim in 1201. The Emirate remained in the possession of his descendants until 1925 when the last Sharif of Mecca, Ali ibn al-Husayn, surrendered the Kingdom of Hejaz to Ibn Saud, Sultan of Nejd. The House of Bolkiah, which rules Brunei, claims Qatadid descent and Sayyid status from their ancestor Sharif Ali's grandfather Emir Rumaythah.

The Saudi conquest of Hejaz, also known as the Hejaz-Nejd War, was a campaign by Abdulaziz al-Saud of the Saudi Sultanate of Nejd to take over the Hashemite Kingdom of Hejaz in 1924–25, ending with conquest and incorporation of Hejaz into the Saudi domain.
