  • Al-Mansur was the brother of Abu al-Abbas and became Caliph in 754 AD.
  • He constructed his new capital at Baghdad.
  • To consolidate his regime, he arranged the murder of Abu Muslim, the general who had lead the armies of al-'Abbas to victory over the Umayyads.
  • He claimed, to be both the religious and secular authority. This alienated Shi'ite Muslims who had wanted the Imam to be made Caliph.
  • Literature and scholarship began to flourish under al-Mansur, particularly the emergence of a Persian influence.
  • There was an increase in the conversion of non-arabs to Islam. Under the Umayyads, this had been discouraged because of the benefits of the jizya, or the tax on non-Moslems.
