For the eleven years of his reign, the question of who was to succeed King Saud was considered a "done deal". However, as the war between the King and Crown Prince grew more heated in the early 1960s, the King let it be known that he was considering changing the line of succession from agnatic seniority to agnatic primogeniture and naming his eldest son Crown Prince. This was unacceptable to the rest of the Royal Clan, and at Faisal's request, Prince Muhammed led a palace coup which ousted the King in late 1964.[9]
