Much has been written on the life of Abdul Aziz bin ´Abdurahman Al-Faisal Al-Sa´ud, one of the most successful, admired and dynamic of Arab leaders to emerge in the first half of the 20th century. Abdul Aziz was in exile with his father from 1892-1901, and had to recapture areas previously held by the Al-Sa´ud dynasty. From 1902-1912 he gathered loyal tribes and incorporated the Akhwan belief-system under his standard, drove back the Turks from al-Hasa in 1913, proceeded with the conquest of the remainder of Najd over 1914–1923, then Hijaz, 1924-25, and Asir, 1926. From 1926 to his death in 1953 he reigned as King, first of Nejd-Hijaz and then the unified state of Saudi Arabia. This set presents original documents from British official sources arranged by issues to depict the methods, policy decisions and diplomatic skills demonstrated by Abdul Aziz in forging a strong, unified State.
