In 691, Zufar was compelled to negotiate a peace with Abd al-Malik, who had consolidated his strength by then.[17] Per their agreement, Zufar abandoned Ibn al-Zubayr's cause in return for a high position in the Umayyad royal court and army.[17] This effectively broke the Yamani monopoly on the Syrian military,[17] and with the collapse of Ibn al-Zubayr's revolt by 692, put an end to Zufar's war with the Banu Kalb and Banu Taghlib.[18] According to the Orientalist Julius Wellhausen, Zufar and later his sons Hudhayl and Kawthar were "amongst the most eminent and notable people at the court of Damascus".[19]
