Upon Ibn Saud's death, his son Saud assumed the throne without incident, but his lavish spending led to a power struggle with his brother, Crown Prince Faisal. In 1964, the royal family forced Saud to abdicate in favor of Faisal, aided by an edict from the country's grand mufti. During this period, some of Ibn Saud's younger sons, led by Talal ibn Abdul Aziz, defected to Egypt, calling themselves the "Free Princes" and calling for liberalization and reform, but were later induced to return by Faisal. They were fully pardoned but were also barred from any future positions in government.
