" There is no clearer illustration of the importance of ideas to politics than the emergence of an Arab state under the Prophet Muhammad. The Arab tribes played an utterly marginal role in world history until that point; it was only Muhammad’s charismatic authority that allowed them to unify and project their power throughout the Middle East and North Africa. The tribes had no economic base to speak of; they gained economic power through the interaction of religious ideas and military organization, and then were able to take over agricultural societies that did produce surpluses.
