This research is based on showing the personality of Al-Ma’moon’s which was characteriseal by education and acquiring more knowledge affecting his internal and external policy. At early of his age, Al-Ma’moon had been taught religion. This lasted for many years. Then he studied scholastic theology until Al-Mu'ta/ila succeeded to conivince him to accept their policy and doctrine. Al-Ma’moon studied pure scientific subjects like, engineering, philosophy and logic. He paid homage to the eighth Imam of Al-Shiites to rule the country after him. This shows the effect of Al-Mu’tazila on the personality of Al-Ma’moon they prefer Ali Mahamuod’s cosin on other Prophet’s companies.They found that he was the only one to rule after the prophet (Mohmmad). AL-Ma'moon had followed the doctrine of Mu'tazila (the problem of creating Qura'n). AL-Ma’moon was peaceful in his religious trends and ideas.On the other side, his external policy, Al-Ma’moon declared that he was ready to sign a long-term treaty with the Byzantiums provided that the emperor should send (Lio) the mathematician scientists to Baghdad to lecture there but this was not achieved because the imperor refused. AL-Ma'moon position was no more than a reflection of his desire to study science and knowledge.
