Mu'awiya died in April 680. According to al-Tabari, Yazid was at his residence in
Huwwarin, located between Damascus and
Palmyra, at the time of his father's death. According to verses of Yazid preserved in Isfahani's , a collection of
Arabic poetry, Yazid was away on a summertime expedition against the Byzantines when he received the news of Mu'awiya's final illness. Based on this and the fact that Yazid arrived in Damascus only after Mu'awiya's death, the historian
Henri Lammens has rejected the reports of Yazid being in Huwwarin. Mu'awiya entrusted supervision of the government to his most loyal associates,
Dahhak ibn Qays al-Fihri and
Muslim ibn Uqba al-Murri, until Yazid's return. He left a
will for Yazid, instructing him on matters of governing the Caliphate. He was advised to beware Husayn and Ibn al-Zubayr, for they could challenge his rule, and instructed to defeat them if they did. Yazid was further advised to treat Husayn with caution and not to spill his blood, since he was the grandson of Muhammad. Ibn al-Zubayr, on the other hand, was to be treated harshly, unless he came to terms.
Oaths of allegiance , Yazid's capital Upon his accession, Yazid requested and received
oaths of allegiance from the governors of the provinces. He wrote to the governor of Medina, his cousin
Walid ibn Utba ibn Abi Sufyan, informing him of Mu'awiya's death and instructing him to secure allegiance from Husayn, Ibn al-Zubayr, and Ibn Umar. The instructions contained in the letter were: Walid sought the advice of Marwan, who suggested that Ibn al-Zubayr and Husayn be forced to pay allegiance as they were dangerous, while Ibn Umar should be left alone as he posed no threat. Husayn answered Walid's summon, meeting Walid and Marwan in a semi-private meeting where he was informed of Mu'awiya's death and Yazid's accession. When asked for his oath of allegiance, Husayn responded that giving his allegiance in private would be insufficient and suggested the oath be made in public. Walid agreed, but Marwan insisted that Husayn be detained until he proffered allegiance. Husayn scolded Marwan and left to join his armed retinue, who were waiting nearby in case the authorities attempted to apprehend him. Immediately following Husayn's exit, Marwan admonished Walid, who in turn justified his refusal to harm Husayn by dint of the latter's close relation to Muhammad. Ibn al-Zubayr did not answer the summons and left for Mecca. Walid sent eighty horsemen after him, but he escaped. Husayn too left for Mecca shortly after, without having sworn allegiance to Yazid. Dissatisfied with this failure, Yazid replaced Walid with his distant Umayyad kinsman
Amr ibn Sa'id. Unlike Husayn and Ibn al-Zubayr, Ibn Umar, Abd al-Rahman ibn Abi Bakr, and
Abd Allah ibn Abbas, who had also previously denounced Mu'awiya's nomination of Yazid, paid allegiance to him.
Battle of Karbala In Mecca Husayn received letters from pro-
Alid Kufans, inviting him to lead them in revolt against Yazid. Husayn subsequently sent his cousin
Muslim ibn Aqil to assess the situation in the city. He also sent letters to Basra, but his messenger was handed over to the governor
Ubayd Allah ibn Ziyad and killed. Ibn Aqil informed Husayn of the large-scale support he found in Kufa, signalling that the latter should enter the city. Informed by some Kufan tribal chiefs () of the goings-on, Yazid replaced the governor of Kufa,
Nu'man ibn Bashir al-Ansari, who had been unwilling to take action against pro-Alid activity, with Ibn Ziyad, whom he ordered to execute or imprison Ibn Aqil. As a result of Ibn Ziyad's suppression and political maneuvering, Ibn Aqil's following began to dissipate and he was forced to declare the revolt prematurely. It was suppressed and Ibn Aqil was executed. Encouraged by Ibn Aqil's letter, Husayn left for Kufa, ignoring warnings from Ibn Umar and Ibn Abbas. The latter reminded him, to no avail, of the Kufans' previous abandonment of his father Ali and his brother Hasan. On the way to the city, he received news of Ibn Aqil's death. Nonetheless, he continued his march towards Kufa. Ibn Ziyad's 4,000-strong army blocked his entry into the city and forced him to camp in the desert of Karbala. Ibn Ziyad would not let Husayn pass without submitting, which Husayn refused to do. Week-long negotiations failed, and in the ensuing hostilities on 10 October 680, Husayn and 72 of his male companions were slain, while his family was taken prisoner. The captives and Husayn's severed head were sent to Yazid. According to the accounts of
Abu Mikhnaf () and Ammar al-Duhni (), Yazid poked Husayn's head with his
staff, although others ascribe this action to Ibn Ziyad. Yazid treated the captives well and sent them back to Medina after a few days.
Revolt of Abd Allah ibn al-Zubayr Following Husayn's death, Yazid faced increased opposition to his rule from Ibn al-Zubayr who declared him deposed. Although publicly he called for a to elect a new caliph, in secret Ibn al-Zubayr let his partisans pay allegiance to him. At first, Yazid attempted to placate him by sending gifts and delegations in an attempt to reach a settlement. After Ibn al-Zubayr's refusal to recognize him, Yazid sent a force led by Ibn al-Zubayr's estranged brother Amr to arrest him. The force was defeated and Amr was taken captive and executed. As well as Ibn al-Zubayr's growing influence in Medina, the city's inhabitants were disillusioned with Umayyad rule and Mu'awiya's agricultural projects, which included the confiscation of their lands to boost government revenue. Yazid invited the notables of Medina to Damascus and tried to win them over with gifts. They were unpersuaded and on their return to Medina narrated tales of Yazid's lavish lifestyle. Accusations included Yazid drinking wine, hunting with hounds, and his love for music. The Medinans, under the leadership of
Abd Allah ibn Hanzala, renounced their allegiance to Yazid and expelled the governor, Yazid's cousin
Uthman ibn Muhammad ibn Abi Sufyan, and the Umayyads residing in the city. Yazid dispatched a 12,000-strong army under the command of Muslim ibn Uqba to reconquer the Hejaz. After failed negotiations, the Medinans were defeated in the
Battle of al-Harra. According to the accounts of Abu Mikhnaf and
al-Samhudi (d. 1533), the city was plundered, whereas per the account of
Awana (d. 764) only the ringleaders of the rebellion were executed. Having forced the rebels to renew their allegiance, Yazid's army headed for Mecca to subdue Ibn al-Zubayr. Ibn Uqba died on the way to Mecca and command passed to
Husayn ibn Numayr al-Sakuni, who
besieged Mecca in September 683. The siege lasted for several weeks, during which the
Ka'ba, the sacred Muslim shrine at the center of the
Mecca Mosque, caught fire. Yazid's sudden death in November 683 ended the campaign and Ibn Numayr retreated to Syria with his army.
Domestic affairs and foreign campaigns The style of Yazid's governance was, by and large, a continuation of the model developed by Mu'awiya. He continued to rely on the governors of the provinces and , as Mu'awiya had, instead of relatives. He retained several of Mu'awiya's officials, including Ibn Ziyad, who was Mu'awiya's governor of Basra, and
Sarjun ibn Mansur, a native Syrian Christian, who had served as the head of the fiscal administration under Mu'awiya. Like Mu'awiya, Yazid received delegations of tribal notables () from the provinces to win their support, which would also involve distributing gifts and bribes. The structure of the caliphal administration and military remained decentralised as in Mu'awiya's time. Provinces retained much of their tax revenue and forwarded a small portion to the Caliph. The military units in the provinces were derived from local tribes whose command also fell to the . , Yazid established the northern border district of
Qinnasrin. Yazid approved a decrease in taxes on the
Arab Christian tribe of Najran upon their request, but abolished the special tax exemption of the
ethno-religious community of
Samaritans, which had been granted to them by previous caliphs as a reward for their aid to the Muslim conquerors. He improved the irrigation system of the fertile lands of the
Ghouta near Damascus by digging a canal that became known as . Toward the end of his reign, Mu'awiya reached a thirty-year peace agreement with the Byzantines, obliging the Caliphate to pay an annual tribute of 3,000 gold coins, 50 horses, and 50 slaves, and to withdraw Muslim troops from the forward bases they had occupied on the island of
Rhodes and the
Anatolian coast. Under Yazid, Muslim bases along the
Sea of Marmara were abandoned. In contrast to the far-reaching raids against the Byzantine Empire launched under his father, Yazid focused on stabilizing the border with Byzantium. In order to improve Syria's military defences and prevent Byzantine incursions, Yazid established the northern Syrian frontier district of
Qinnasrin from what had been a part of
Hims, and garrisoned it. Yazid reappointed
Uqba ibn Nafi, the conqueror of the central North African region of
Ifriqiya whom Mu'awiya had deposed, as governor of Ifriqiya. In 681, Uqba launched a large-scale expedition into western North Africa. Defeating the
Berbers and the Byzantines, Uqba reached the Atlantic coast and captured
Tangier and
Volubilis. He was unable to establish permanent control in these territories. On his return to Ifriqiya, he was ambushed and killed by a Berber–Byzantine force at the
Battle of Vescera, resulting in the loss of the conquered territories. In 681 Yazid appointed Ibn Ziyad's brother
Salm ibn Ziyad as the governor of the northeastern border province of
Khurasan. Salm led several campaigns in
Transoxiana (Central Asia) and raided
Samarqand and
Khwarazm, but without gaining a permanent foothold in any of them. Yazid's death in 683 and the subsequent
chaos in the east ended the campaigns. ==Death and succession==
