Abdullah of Saudi Arabia in the context of "Fahd of Saudi Arabia"

The king of Saudi Arabia, officially the king of the Kingdom of Saudi Arabia (Arabic: ملك المملكة العربية السعودية, romanized: Malik al-Mamlakat al-ʿArabiyat as-Suʿūdiyya), is head of state of the Kingdom of Saudi Arabia, who holds absolute power. He is the head of the Saudi Arabian royal family, the House of Saud. The king is the commander-in-chief of the Saudi Arabian Armed Forces and the head of the Saudi national honors system. The king is called the "Custodian of the Two Holy Mosques" (خادم الحرمين الشريفين; Khadim al-Haramayn aš-Šarīfayn), a title that signifies Saudi Arabia's jurisdiction over the mosques of Masjid al-Haram in Mecca and Al-Masjid an-Nabawi in Medina. The title has been used many times through the history of Islam. The first Saudi king to use the title was Faisal; however, King Khalid did not use the title after him. In 1986, King Fahd replaced "His Majesty" with the title of Custodian of the Two Holy Mosques, and it has been since used by both King Abdullah and King Salman. The king has been named the most powerful and influential Muslim and Arab leader in the world according to The Muslim 500.

The Crown Prince of Saudi Arabia (Arabic: ولي عهد المملكة العربية السعودية, romanized: Waliyy ʿAhd al-Mamlaka al-ʿArabiyya as-Suʿūdiyya) is the second-most important position in Saudi Arabia, second to the King, and is his designated successor. Currently, the Crown Prince assumes power with the approval of the Allegiance Council after he is nominated by the King. This system was introduced to the country during the reign of King Abdullah. In the absence of the King, an order is issued to have the Crown Prince manage the affairs of the state until the King's return.
