Second Fitna participant Ubayd Allah ibn Ziyad
Revolts against Yazid
Revolt of Husayn ibn Ali
Husayn had considerable support in Kufa. The inhabitants of the town had fought the Umayyads and their Syrian allies during the First Fitna. They were dissatisfied with Hasan's abdication and strongly resented Umayyad rule. After the death of Hasan in 669, they had attempted unsuccessfully to interest Husayn in revolting against Mu'awiya. After the latter died, the pro-Alids of Kufa once again invited Husayn to lead them in revolt against Yazid. To assess the situation, the Mecca-based Husayn sent his cousin Muslim ibn Aqil, who gained widespread support in Kufa and suggested Husayn join his sympathizers there. Yazid removed Nu'man ibn Bashir al-Ansari as governor due to his inaction over Ibn Aqil's activities and replaced him with Ubayd Allah ibn Ziyad, then governor of Basra. On Yazid's instructions, Ibn Ziyad suppressed the rebellion and executed Ibn Aqil. Encouraged by his cousin's letter, and unaware of his execution, Husayn left for Kufa. To track him down, Ibn Ziyad stationed troops along the routes leading to the city. He was intercepted at Karbala, a desert plain north of Kufa. Some 4,000 troops arrived later to force his submission to Yazid. After a few days of negotiations and his refusal to submit, Husayn was killed along with some 70 of his male companions in the Battle of Karbala on 10 October 680.Struggle for control of Syria
After Yazid's death, his son and nominated successor Mu'awiya II became caliph, but his authority was limited to certain parts of Syria. Mu'awiya II died after a few months with no suitable Sufyanid (Umayyads of the line of Mu'awiya; descendants of Abu Sufyan) candidate to succeed him. The northern Syrian Qays tribes supported Ibn al-Zubayr, as did the governors of the Syrian districts of Hims, Qinnasrin and Palestine, while the Damascus governor Dahhak ibn Qays was also leaning toward Ibn al-Zubayr. Moreover, many Umayyads, including Marwan ibn al-Hakam, the most senior among them at the time, were willing to recognize him. Pro-Umayyad tribes, particularly the Banu Kalb, dominated the district of Jordan and had support in Damascus. They were determined to install an Umayyad. The Kalbite chief Ibn Bahdal was related in marriage to the Sufyanid caliphs, and his tribe had held a privileged position under them. He wanted to see Yazid's younger son Khalid on the throne. Ibn Ziyad convinced Marwan to put forward his own candidacy as Khalid was considered too young for the post by the non-Kalbites in the pro-Umayyad coalition. Marwan was acknowledged as caliph in a shura of pro-Umayyad tribes summoned to the Kalbite stronghold of Jabiya in June 684. Pro-Zubayrid tribes refused to recognize Marwan and the two sides clashed at the Battle of Marj Rahit in August. The pro-Zubayrid Qays under Dahhak's leadership were slaughtered and many of their senior leaders were slain.Marwan's accession was a turning point as Syria was reunited under the Umayyads and the Umayyads' focus was turned to regaining lost territories. Marwan and his son Abd al-Aziz expelled the Zubayrid governor of Egypt with the help of local tribes. The Zubayrid attack on Palestine led by Mus'ab was repulsed, but an Umayyad campaign to retake the Hejaz was defeated near Medina. Marwan dispatched Ibn Ziyad to restore Umayyad control in Iraq. After Marwan died in April 685, he was succeeded by his son Abd al-Malik.
