The super-elites in the Saudi royal family are the Sudairi Seven...or Sudairi Six, since King Fahd croaked in 2005. They were the seven sons of King Abdul-Aziz by his favorite wife, who came from the Sudairi tribe. He also married several other women from that tribe.
IOW, the clan is sort of like a polygamous Bu$h family in
thobes (that gold-trimmed robe that caught your eye) and
ghuttras (the male head-dress, with the braided trim that us Grumpy Infidels invariably referred to as "the fan belts.")
I came across most of this usless information because I spent 2 years living/working in Saudi Arabia, and I've spent almost that long in Egypt. I'm writing this from Alexandria. Egypt, that is, not Virginia. :-)
The current Saudi King, Abdullah, is NOT one of the Sudairi Seven, having the misfortune to be born of a different mother. Allegedly this has always caused some strife in the royal family.
There was some talk about bypassing Abdullah and making Prince Sultan the king. (Sultan is one of the Sudairi Seven.) However, Sultan is happy running the Ministry Of Defense and didn't want the job. One of Sultan's sons is the famous "Bandar Bush," former Saudi Ambassador to the U.S.
For many years, Abdullah was known as one of the most conservative and anti-Western members of the royal family. The kingdom apparently started rehabilitating his image and turning him into a moderate when it became obvious that he would take over as king.
Probably the most...interesting member of the Sudairi Seven was Prince Turki, former head of the Saudi Intelligence Services:
On 15 August 2002, he was one of three Saudi princes sued for allegedly helping to finance the terrorist attacks of 11th September 2001, the other two being Prince Sultan bin Abdul Aziz and Prince Mohammed bin Faisal.
The lawsuit sought damages from members of the Saudi royal family, Saudi banks and Saudi corporations, who had extensive financial holdings in the US. Among the defendants were two prominent members of the Saudi royal family, Prince Sultan bin Abdelaziz al-Saud, the defense minister, and Prince Turki bin Faisal, Saudi ambassador to Britain. The suit alleges that Prince Sultan "publicly supported and funded several Islamic charities that were sponsoring Osama bin Laden" and that Prince Turki negotiated a deal in which Al Qaeda agreed to end efforts to subvert the Saudi monarchy in exchange for a Saudi promise not to extradite terrorist leaders.http://www.globalsecurity.org/military/world/gulf/turki-bin-faisal.htm
