Records of Saudi Arabia 1902–1960 traces the evolution and development of the Saudi state from the momentous reconquest of Riyadh in 1902 by 'Abd al 'Aziz bin 'Abd al-Rahman bin Faisal al Sa'ud, Amir of Najd. The collection offers historical evidence for the creation of Saudi Arabia - the capture of Riyadh, the conquests of Al Hasa and the Hijaz, the occupation of Taif, Jedda, Mecca and Medina, and the proclamation of the Kingdom. It includes many original letters of King Abdulaziz and illustrates the political, social and economic changes which in just over half a century transformed the desert amirate into one of the richest countries in the world. The early years of this collection contain the key events, including a retrospective volume covering the nineteenth century, and aim to give a wide base of information from which further research will be stimulated.
