Saud was born around 1898. He was born to
Abdulaziz bin Mutaib Al Rashid, the reigning Rashidi emir at the time, and Moudi bint Sabhan Al Sabhan, who had previously been married to
Muhammad bin Abdullah Al Rashid. On April 12, 1906, his father was killed in the
Battle of Rawdat Muhanna, with Saud's older half-brother, Mutaib, succeeding him as emir. Mutaib's maternal uncles Saud, Faisal, and Sultan bin Hamoud Al Rashid vied for power however, and on December 31, 1906, he and his two full brothers Mishaal and Muhammad were killed by them. Saud was saved and taken to
Medina by his uncle Hamoud bin Sabhan Al Sabhan. Sultan bin Hamoud Al Rashid then became emir, though he was vastly unpopular, and he and his brothers agreed that he should go to Tayma and Saud bin Hamoud Al Rashid become emir. When he left, however, Saud was informed that he had taken all the treasure and thus he summoned the townspeople, and caught up with him at Mogug, killing him. In September 1908, Hamoud bin Sabhan Al Sabhan returned from Medina and killed Saud bin Hamoud, proclaiming ten-year-old Saud bin Abdulaziz as emir. ==Reign==
