king Abdul Aziz - King Abdul Aziz King Abdul Aziz bin Abdul Rahman Al Saud (Ibn Saud) (founder of the Kingdom of Saudi Arabia) King Abdul Aziz bin Abdul Rahman Al Saud (known as Ibn Saud) was a tall, imposing figure, a natural leader of men. He knew instinctively how to judge men and, as his rule progressed, how best to exploit the natural resources of his country for the benefit of his people. His achievement, the unification of many warring tribes all proud of their own lineage and traditions, laid the foundations for the modern state of Saudi Arabia. His success derived from his faith in Islam and his determination to maintain and build on the traditions of the region. It is the unique combination of faith and respect for tradition, while adapting to the technological developments of modern world, which characterizes the Kingdom of Saudi Arabia today. The judgment of Chambers Biographical Dictionary is very much to the point. It simply states that Ibn Saud 'was the outstanding Arab ruler of his time.'
