Abdullah, Salman and Muqrin are all sons of the founder of modern Saudi Arabia, King Abdulaziz, usually referred to as Ibn Saud, who died in 1953. King Salman called on the royal family's Allegiance Council to recognise Muqrin as his heir.
The most influential member of the Royal family is the King of Saudi Arabia, currently King Salman. The succession to the Saudi Arabian throne was designed to pass from one son of the first king, Ibn Saud, to another. The next in line, Crown Prince Muhammad bin Nayef is also from the ruling House of Saud, and the king-appointed cabinet includes more members of the royal family. While the monarchy is hereditary now, future Saudi kings will be chosen by a committee of Saudi princes, in line with a 2006 royal decree.
