full_context: Document 1: Siege of Medina: Medina, an Islamic holy city in Arabia, underwent a long siege during World War I. Medina was at the time part of the Ottoman Empire. In the war, the Ottoman Empire sided with the Central Powers. Sharif Hussain of Mecca revolted against the caliph and the Ottoman Empire which, under the leadership of the nationalistic Young Turks, had ignored the wishes of the Caliph and sided with the Central Powers. Hussain instead sided with the British Empire. T. E. Lawrence was instrumental in this revolt. Hussain occupied Mecca and besieged Medina. It was one of the longest sieges in history that lasted till even after the end of war. Fahreddin Pasha was the defender of Medina. Some celebrated him as ""the Lion of the Desert"" despite the suffering of those who remained in Medina. The siege lasted two years and seven months.
Document 2: Religion in Saudi Arabia: The official form of Islam is Sunni of the Hanbali school, in its Salafi version. According to official statistics, 75–85% of Saudi Arabian citizens are Sunni Muslims, 10–15% are Shia. (More than 30% of the population is made up of foreign workers  who are predominantly but not entirely Muslim.) It is unknown how many Ahmadis there are in the country. The two holiest cities of Islam, Mecca and Medina, are in Saudi Arabia. For many reasons, non-Muslims are not permitted to enter the holy cities although some Western non-Muslims have been able to enter, disguised as Muslims.
Document 3: Madrasa: Al-Azhar University, founded in Cairo, Egypt in 975 by the Ismaʻīlī Shīʻī Fatimid dynasty as a jāmiʻah, had individual faculties for a theological seminary, Islamic law and jurisprudence, Arabic grammar, Islamic astronomy, early Islamic philosophy and logic in Islamic philosophy. The postgraduate doctorate in law was only obtained after "an oral examination to determine the originality of the candidate's theses", and to test the student's "ability to defend them against all objections, in disputations set up for the purpose." ‘Abd al-Laṭīf al-Baghdādī also delivered lectures on Islamic medicine at al-Azhar, while Maimonides delivered lectures on medicine and astronomy there during the time of Saladin. Another early jāmiʻah was the Niẓāmīyah of Baghdād (founded 1091), which has been called the "largest university of the Medieval world." Mustansiriya University, established by the ʻAbbāsid caliph al-Mustanṣir in 1233, in addition to teaching the religious subjects, offered courses dealing with philosophy, mathematics and the natural sciences.
Document 4: Saudi Arabia: Arab dynasties originating from modern-day Saudi Arabia founded the Rashidun (632–661), Umayyad (661–750), Abbasid (750–1517) and Fatimid (909–1171) caliphates as well as numerous other dynasties in Asia, Africa and Europe.The area of modern-day Saudi Arabia formerly consisted of mainly four distinct regions: Hejaz, Najd and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia ('Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud. He united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. Saudi Arabia has since been a totalitarian absolute monarchy, effectively a hereditary dictatorship governed along Islamist lines. The ultraconservative Wahhabi religious movement within Sunni Islam has been called "the predominant feature of Saudi culture", with its global spread largely financed by the oil and gas trade. Saudi Arabia is sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca) and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. The state's official language is Arabic.

Document 12: Ottoman Empire: The history of the Ottoman Empire during World War I began with the Ottoman engagement in the Middle Eastern theatre. There were several important Ottoman victories in the early years of the war, such as the Battle of Gallipoli and the Siege of Kut. The Arab Revolt which began in 1916 turned the tide against the Ottomans on the Middle Eastern front, where they initially seemed to have the upper hand during the first two years of the war. The Armistice of Mudros was signed on 30 October 1918, and set the partition of the Ottoman Empire under the terms of the Treaty of Sèvres. This treaty, as designed in the conference of London, allowed the Sultan to retain his position and title. The occupation of Constantinople and İzmir led to the establishment of a Turkish national movement, which won the Turkish War of Independence (1919–22) under the leadership of Mustafa Kemal (later given the surname "Atatürk"). The sultanate was abolished on 1 November 1922, and the last sultan, Mehmed VI (reigned 1918–22), left the country on 17 November 1922. The caliphate was abolished on 3 March 1924.
Document 13: Partition of the Ottoman Empire: The partition of the Ottoman Empire (Armistice of Mudros, 30 October 1918 -- Abolition of the Ottoman Sultanate, 1 November 1922) was a political 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. As world war loomed, the Ottoman Empire sought protection but was rejected by Britain, France, and Russia, and finally formed 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 led to the rise in the Middle East of Western powers such as Britain and France and brought 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 post-Ottoman states until after World War II.
Document 14: Mehmed VI: The First World War was a disaster for the Ottoman Empire. British and allied forces had conquered Baghdad, Damascus, and Jerusalem during the war and most of the Ottoman Empire was divided amongst the European allies. At the San Remo conference of April 1920, the French were granted a mandate over Syria and the British were granted one over Palestine and Mesopotamia. On 10 August 1920, Mehmed's representatives signed the Treaty of Sèvres, which recognised the mandates and recognised Hejaz as an independent state.
