The House of Saud are no royalty as such.
They were merely the leader of a tribe of foul smelling, unwashed, camel riding, Bedous.
It maybe noted that by 1932, Ibn Saud had disposed of all his main rivals and consolidated his rule over much of the Arabian Peninsula. He declared himself king of the Kingdom of Saudi Arabia that year. Previously, he had gone through several titles, starting with "Sultan of Najd" and ending with "King of Hijaz and Najd and their dependencies." Ibn Saud's father, Abdul Rahman retained the honorary title of "imam." A few years later, in 1937, American surveyors discovered near Dammam what later proved to be Saudi Arabia's vast oil reserves. Before the discovery of oil, many family members were destitute.
That they are barbaric is obvious. King Saud succeeded to the throne on his father's death in 1953. However, an intense rivalry between the King and his half-brother, Prince Faisal emerged, fueled by doubts in the royal family over Saud's competence. As a consequence, Saud was deposed in favour of Faisal in 1964. The major event of King Faisal's reign was the 1973 oil crisis, when Saudi Arabia, and the other Arab oil producers, tried to put pressure on the US to withdraw support from Israel through an oil embargo. Faisal was assassinated in 1975 by his nephew, Prince Faisal bin Musaid.
If the House of Saud is Royalty, then our own Singh is King!
