The tall, stately Prince Saud was a fixture of Mideast diplomacy, representing the oil-rich Gulf powerhouse as it wielded its influence in crisis after crisis shaking the region from Lebanon's civil war in the 1970s and 1980s, through multiple rounds of Arab-Israeli peace efforts, the 1990 Iraqi invasion of neighboring Kuwait and the subsequent Gulf War, al-Qaida's 9/11 attacks in the United States, the 2003 U.S.-led invasion of Iraq to the current day's tensions between the Gulf and Iran, Arab Spring uprisings, Syrian civil war and the spread of Islamic State group extremists.
The prince, who took the ministry post in 1975, retired on April 29, citing health reasons. At the time, U.S. Secretary of State John Kerry hailed him, saying he "has not just been the planet's longest-serving Foreign Minister but also among the wisest." He was succeeded in the post by Adel al-Jubeir, who before that was Saudi Arabia's ambassador in Washington.
Soft spoken, he often showed a sense of humor not often seen among the publicly stolid royal family.
"The history of Saudi foreign policy is al-Faisal, both him and his father," he said. ""It's how the world knew Saudi Arabia, through al-Faisal."
He led Saudi diplomacy over a period that saw the kingdom once better known for behind-the-scenes influence become more overt in throwing its weight in affairs across the Mideast.
