Custodian of the Two Holy Mosques
When King Khalid died on 13 June 1982, Fahd succeeded to the throne being the fifth king of Saudi Arabia. However, the most active period of his life was not his reign, but when he was Crown Prince. He adopted the title "Custodian of the Two Holy Mosques" in 1986, replacing "His Majesty", to signify an Islamic rather than secular authority.
