Bin Laden was one of more than 50 children of Muhammad bin Laden, a self-made billionaire who, after immigrating to Saudi Arabia from Yemen as a labourer, rose to direct major construction projects for the Saudi royal family. By the time of Muhammad’s death in an airplane accident in 1967, his company had become one of the largest construction firms in the Middle East, and the bin Laden family had developed a close relationship with the Saudi royal family.
Osama bin Laden studied business administration at King Abdul Aziz University in Jeddah, where it is likely that he also received instruction in religious studies from Muḥammad Quṭb, brother of the Islamic revivalist Sayyid Quṭb, and Abdullah Azzam, a militant leader. His time at the university was key to his future role as leader of al-Qaeda, not only in influencing his radical views but also in providing him with the skill to market al-Qaeda.
