Is the government in Saudi Arabia by inherited?
Currently, the King of Saudi Arabia is from the tribe of Al-Saud, the ruling tribe since the foundation of the country. The current king is King Abdullah bin Abdul Aziz Al-Saud, 4th son of founder of Saudi Arabia, Abdul Aziz Al-Saud. The next king is the currently Crown Prince Sultan bin Abdul Aziz Al-Saud. But after that, it is still not decided. It will be a hard time for Saudi Arabia, the members of the Al-Saud family will fight to get the title. The king would be either chosen from the close relatives, the Emirs of the Provinces, or something else. The future is uncertain.
