The next major challenge to Yazid's rule emanated from the Hejaz where Abd Allah ibn al-Zubayr, the son of al-Zubayr ibn al-Awwam and grandson of Abu Bakr, advocated for a "shura" among the Quraysh to elect the caliph and rallied opposition to the Umayyads from his headquarters in Islam's holiest sanctuary, the Ka'aba in Mecca. The Ansar and Quraysh of Medina also took up the anti-Umayyad cause and in 683 expelled the Umayyads from the city. Yazid's Syrian troops routed the Medinese at the Battle of al-Harra and subsequently plundered Medina before besieging Ibn al-Zubayr in Mecca. The Syrians withdrew upon news of Yazid's death in 683, after which Ibn al-Zubayr declared himself caliph and soon after gained recognition in most provinces of the Caliphate, including Iraq and Egypt. In Syria Ibn Bahdal secured the succession of Yazid's son and appointed successor Mu'awiya II, whose authority was likely restricted to Damascus and Syria's southern districts. Mu'awiya II had been ill from the beginning of his accession, with al-Dahhak assuming the practical duties of his office, and he died in early 684 without naming a successor. His death marked the end of the Umayyads' Sufyanid ruling house, called after Mu'awiya I's father Abu Sufyan. The eldest surviving Sufyanid, al-Walid ibn Utba, the son of Mu'awiya I's full brother, died shortly after Mu'awiya II's death, while another paternal uncle of the deceased caliph, Uthman ibn Anbasa ibn Abi Sufyan, who had support from the Kalb of the Jordan district, recognized the caliphate of his maternal uncle Ibn al-Zubayr. Ibn Bahdal favored Mu'awiya II's brothers Khalid and Abd Allah for the succession, but they were viewed as too young and inexperienced by most of the pro-Umayyad tribal nobility in Syria.
