I found interesting in class when the teacher told us that this family had been in the throne for years, so i took the liberty to investigate a little about this and now I will passed to you.
The al-Saud family has ruled what is now Saudi Arabia since the 1920s, when Abdul Aziz overpowered rivals from other tribes and unified the country. The root of the succession problem lies in the fact that Abdul Aziz fathered some 45 sons, of whom 23 are still alive, and did not specify how his successors were to be chosen. Until now it has been an informal process among the princes; it is not based on birth order, but upon negotiation and compromise within the family
There were alot of sons. They have been years since the family rules.
