Abdulaziz bin Mithab (Arabic: عبد العزيز بن متعب‎). (ruled: 1897–1906), a son of the third Rashidi emir, he was adopted by his uncle Mohammed, the fifth amir, and brought up to be his heir. After Mohammed died of natural causes, Abdulaziz succeeded him unopposed. However, the Rashidi rule was insecure, as their Ottoman allies were unpopular and weakening. In 1904 the young Ibn Saud, the founder of Saudi Arabia, returned from Kuwait with a small force and retook Riyadh.
