Saud of Saudi Arabia
In 1953, Saud of Saudi Arabia succeeded as the king of Saudi Arabia, on his father's death, until 1964 when he was deposed in favour of his half brother Faisal of Saudi Arabia, after an intense rivalry, fuelled by doubts in the royal family over Saud's competence. In 1972, Saudi Arabia gained a 20 per cent control in Aramco, thereby decreasing US control over Saudi oil.
