Faisal bin Abdulaziz Al Saud born c. 1906, Riyadh, Arabia (now in Saudi Arabia)—died March 25, 1975, Riyadh.

Faisal was a son of King Ibn Saud and a brother of King Saud. He was appointed foreign minister and viceroy of Hejaz in 1926 after his father conquered that province, in which lies the holy city of Mecca.

Faisal bin Abdulaziz Al Saud in 1934 he led a victorious campaign against Yemen. He represented Saudi Arabia at the United Nations Conference of 1945 and was later ambassador to the UN General Assembly.

After Saud’s accession in 1953, Faisal became crown prince and foreign minister. In 1958, during an economic crisis, Saud gave him full executive powers. Faisal resigned in 1960 but returned in 1962, and in March 1964 he assumed all powers as viceroy. Saud was deposed by religious leaders, senior members of the ruling family, and the Council of Ministers, and Faisal became king in November 1964.

Domestically, Faisal was much more active and modernizing than his predecessors in economic and educational programs. His bureaucratic reforms, moreover, made the state’s finances and operations more efficient, while his assertion of state involvement in Aramco allowed greater supervision and leverage over the country’s oil resources. Foreign affairs under his reign also saw Saudi Arabia become more assertive in the region, challenging the dominance in regional leadership long held by Egypt. He supported the royalists in Yemen when they resisted, though unsuccessfully, the new republican government backed by Egypt, but he joined the Arab states in the 1967 Six-Day War.

Though in failing health, he remained active in his office until he was shot to death by his nephew Prince Fayṣal ibn Musāʿid. King Faisal was succeeded by his half brother Crown Prince Khalid ibn ʿAbd al-ʿAzīz Āl Saʿūd.
