Ibn Saud was born on 15 January 1875 in Riyadh in the region called Najd in central Arabia.[6][7] He was the son of Abdul Rahman bin Faisal, last ruler of the Emirate of Nejd, the "Second Saudi State", a tribal sheikhdom centered on Riyadh. His family, the House of Saud, had been a power in central Arabia for the previous 130 years. Under the influence and inspiration of Wahhabi Islam, the Saudis had previously attempted to control much of the Arabian peninsula in the form of the Emirate of Diriyah, the "First Saudi State", until its destruction by an Ottoman army in the Ottoman–Wahhabi War in the early nineteenth century.[8] Ibn Saud's mother was a member of the Sudairi family,[9] Sarah Al Sudairi.[10] She died in 1910.[6]
