33 MARWAN II (744-750 A.D./127-132 A.H.)
On his accession Marwan was surrounded by difficulties. The support given to him by the Mudar clan and the discomfiture inflicted by them rankled in the bosom to the Yamani tribes. The Khawarij raised the standard of rebellion and the Hashimi (or Abbasid) conspiracy spread with alarming rapidity. Disaffection and discontent spread all over the empire. Even the men of Kalb and the Syrian troops became disaffected. Marwan’s reign was one of continual struggle which would have put the rebellion down, had the Syrian forces held a united front, but that they did not do out of tribal jealousies and the result was fatal to the Umayyad rule.
