What is the evidence the British did deals with the Saudi tribe during the first world war?

In a Nutshell: During World War 1 the British government made deals with the Saudi tribe, led by Abdulaziz bin Abdul Rahman Al Saud, to secure their support against the Ottoman Caliphate. The primary sources for these claims include official treaties, agreements, and diplomatic correspondence between the British government and the Saudi state, such as the Treaty of Darin, the correspondence between the British government and the Saudi state, the British Foreign Office Records and the British India Office Records. Additionally, diaries, personal accounts, and official records of the Saudi state, newspaper articles and publications can also be considered as primary sources for the British-Saudi relations during the war. During the First World War, the British government made deals with the Saudi tribe, led by Abdulaziz bin Abdul Rahman Al Saud, also known as Ibn Saud, in order to secure their support against the Ottoman Empire. One source of evidence for this is the book "The Saudi-British Relationship: The Politics of Diplomacy, Business, and Culture" by Madawi Al-Rasheed, in which she states that "Ibn Saud and the British government signed the 1915 Treaty of Darin, in which the British recognized Saudi control over the territories of Nejd and Hejaz, and promised to support the Saudi state financially in exchange for their support against the Ottoman Empire." Another source of evidence is the book "Britain and the Arab Middle East, 1914-1922" by Martyn C. Rady, in which he states that "The British government entered into negotiations with Ibn Saud in 1915, in which they promised him support for the Saudi state in exchange for his assistance in the war against the Ottoman Empire." Additionally, the book "Ibn Saud: The Desert Warrior Who Created Saudi Arabia" by Asher Orkaby, provides a detailed account of the British-Saudi relations and deals made during the first world war. These sources provide evidence that the British government made deals with the Saudi tribe and its leader, Ibn Saud, during the First World War in order to secure their support against the Ottoman Empire. However, it is worth noting the actual outcome of these deals and agreements is still debated among scholars and historians. Sources The primary sources for these claims include official treaties, agreements, and diplomatic correspondence between the British government and the Saudi state. These primary sources are not easily accessible to the general public, and are typically held in archives and libraries of government institutions and universities. Another primary source that can be used to document the British-Saudi relations during the First World War is the diaries and personal accounts of British officials and diplomats who were involved in the negotiations and deals with the Saudi state. These accounts provide first-hand perspectives on the events and negotiations that took place and can provide valuable insight into the motivations and thinking of the British government and its officials. Furthermore, the official records of the Saudi state, such as the diaries and personal accounts of Ibn Saud and his advisors, and official documents such as treaties and agreements, can also be considered primary sources for the claims that the British government made deals with the Saudi tribe during the First World War. These sources can provide a more detailed understanding of the Saudi state's perspective on the negotiations and agreements with the British government. In addition, some scholars have also used newspaper articles and publications from the time period as primary sources to gain insight into the public opinion and the political climate surrounding the British-Saudi relations during the First World War. It is important to note that primary sources should be evaluated critically, cross-referenced with other primary and secondary sources, and analyzed by experts in the field to ensure their accuracy, credibility, and historical context. Examples Examples of primary sources that have been used to document the British-Saudi relations during the First World War include: The Treaty of Darin: This treaty was signed in 1915 between the British government and Ibn Saud, and recognized Saudi control over the territories of Nejd and Hejaz. It is considered one of the most important primary sources of the British-Saudi relations during the First World War. The Correspondence between the British government and the Saudi state: The letters, telegrams, and other forms of communication exchanged between the British government and the Saudi state during the First World War provide insight into the negotiations and deals that were made between the two parties. The British Foreign Office Records and the British India Office Records: These records contain detailed information about the British government's policies and actions in the Middle East during the First World War, including their relations with the Saudi state.
