King of Saudi Arabia
The first King of Saudi Arabia to assume the title was Faisal bin Abdul Aziz (1906–1975). His successor Khalid did not use the title, but the latter's successor Fahd did, replacing the term "His Majesty" with it. The current king, Salman bin Abdulaziz Al Saud, took the same title after the death of King Abdullah, his half brother, on 23 January 2015.
