Prince Turki I bin Abdul-Aziz Al Saud (1900-1919) (Arabic: تركي الأول بن عبد العزيز آل سعود) was the eldest son of King Abdul-Aziz of Saudi Arabia and was the Crown Prince of Najd. He was Crown Prince from his father's conquest of Riyadh on January 15, 1902, to his early death. He accompanied his father during the conquest of the Arabian Peninsula at a young age, and witnessed battles in Kuwait and Al-Hasa. However, he died during the 1918 flu pandemic that killed many others in the region. His father was said to be deeply saddened by his death.[1]
Turki's wife was pregnant at the time of his death and she gave birth to his child Faisal, who years later was briefly a minister in the government of King Saud.
The law of succession was changed immediately after Turki's death, so that the kingship of Najd, and later all Saudi Arabia would, starting with Saud, pass from brother to brother and not father to son.
