Sa'ad I bin Abdul Rahman bin Faisal Al Saud
Sa'ad bin Abdul Rahman Al Saud (1888–1915) was the only full brother of Abdulaziz, founder of the modern state of Saudi Arabia. He was one of Ibn Saud's most devoted supporters and a key lieutenant in the early military campaigns. He was called Sa'ad the First, because his stepmother had a son named Sa'ad II later years.
