The Sudairi Seven's rise to power can be traced back to the accession of King Faisal and his earlier struggle with King Saud. Although not a Sudairi himself, Faisal, in his struggle to overthrow Saud, relied heavily upon the seven Sudairi brothers. One of the earliest significant roles played by the Sudairi Seven was in March 1962 when they collaborated with Crown Prince Faisal. They threatened five members of King Saud's cabinet to submit their resignations following the announcement of the constitution by the king which had been drafted by the members of the Free Princes movement with the help of Egyptian lawyers. The ministers, including Oil Minister Abdullah Tariki, resigned from the office as a result of their extensive campaign against them. Then in 1962, as prime minister and heir apparent, Prince Faisal appointed Prince Fahd as interior minister, Prince Sultan as defense minister, and Prince Salman as governor of Riyadh. All were key posts. Following his accession to the throne after King Saud's deposition in 1964, King Faisal continued to favor the Sudairi Seven as his allies.
