The History of the Hashemites and the House of Saud
The current Middle East crisis between the Israelis and the Arab world is the result of some of the most incredible blunders in history. Perhaps there is no greater blunder than some promises made by a British regional military commander to a bunch of backward camel-riding Arab Muslims from Western Arabia. Lt. Colonel T. E. Lawrence was sent by the British to recruit the enlistment of the help of the Arab Muslim tribes of the western Arabian region. The British needed them to act as irregular raiders against the eastern flank of the Ottoman Turkish army, thus helping the British Army to defeat them in the greater Middle East region during WWI. The principle tribe Lawrence enlisted was known as the Hashemites, who were then the guardians of the holy Muslim sites of Mecca and Medina, until the rise of Ibn Saud.
