Yazid I
Yazid ibn Mu'awiya ibn Abi Sufyan, commonly known as Yazid I, was the second caliph of the Umayyad Caliphate, ruling from April 680 until his death in November 683. His appointment by his father Mu'awiya I was the first hereditary succession to the caliphate in Islamic history. His caliphate was marked by the death of Muhammad's grandson Husayn ibn Ali and the start of the crisis known as the Second Fitna.
During his father's caliphate, Yazid led several campaigns against the Byzantine Empire including an attack on the Byzantine capital, Constantinople. Yazid's nomination as heir apparent in by Mu'awiya was opposed by several Muslim grandees from the Hejaz region, including Husayn and Abd Allah ibn al-Zubayr. The two men refused to recognize Yazid following his accession and took sanctuary in Mecca. When Husayn left for Kufa in Iraq to lead a revolt against Yazid, he was killed with his small band of supporters by Yazid's forces in the Battle of Karbala. Husayn's death caused resentment in the Hejaz, where Ibn al-Zubayr called for a consultative assembly to elect a new caliph. The people of Medina, who supported Ibn al-Zubayr, held other grievances toward the Umayyads. After failing to gain the allegiance of Ibn al-Zubayr and the people of the Hejaz through diplomacy, Yazid sent an army to suppress their rebellion. The army defeated the Medinans in the Battle of al-Harra in August 683 and the city was plundered. Afterward, Mecca was besieged for several weeks until the army withdrew as a result of Yazid's death in November 683. The Caliphate fell into a nearly decade-long civil war, ending with the establishment of the Marwanid dynasty.
Yazid continued Mu'awiya's decentralized model of governance, relying on his provincial governors and the tribal nobility. He abandoned Mu'awiya's ambitious raids against the Byzantine Empire and strengthened Syria's military defenses. No new territories were conquered during his reign. Yazid is considered an illegitimate ruler and a tyrant by many Muslims due to his hereditary succession, the death of Husayn, and his attack on Medina. Modern historians take a milder view, and consider him a capable ruler, albeit less successful than his father.
Early life
Yazid was born in Syria. His year of birth is uncertain, placed between 642 and 649. His father was Mu'awiya ibn Abi Sufyan, then governor of Syria under Caliph Uthman. Mu'awiya and Uthman belonged to the wealthy Umayyad clan of the Quraysh tribe, a grouping of Meccan clans to which the Islamic prophet Muhammad and all the preceding caliphs belonged. Yazid's mother, Maysun, was the daughter of Bahdal ibn Unayf, a chieftain of the powerful Bedouin tribe of Banu Kalb. She was a Christian, like most of her tribe. Yazid grew up with his maternal Kalbite kin, spending the springs of his youth in the Syrian Desert; for the remainder of the year he was in the company of the Greek and native Syrian courtiers of his father, who became caliph in 661.During his father's caliphate, Yazid led several campaigns against the Byzantine Empire, which the Caliphate had been trying to conquer, including an attack on the Byzantine capital, Constantinople. Sources give several dates for this between 49 AH and 55 AH. Muslim sources offer few details of his role in the campaigns, possibly downplaying his involvement due to the controversies of his later career. He is portrayed in these sources as having been unwilling to participate in the expedition to the chagrin of Mu'awiya, who then forced him to comply. However, two eighth-century non-Muslim sources from al-Andalus, the Chronicle of 741 and the Chronicle of 754, both of which likely drew their material from an earlier Arabic work, report that Yazid besieged Constantinople with a 100,000-strong army. Unable to conquer the city, the army captured adjacent towns, acquired considerable loot, and retreated after two years. Yazid also led the hajj on several occasions.
Nomination as caliph
The third caliph Uthman drew the ire of the Muslim settlers of the conquered lands as a consequence of his controversial policies, which were seen by many as nepotistic and interfering in provincial affairs. In 656 he was killed by the provincial rebels in Medina, then capital of the Caliphate, after which Ali, the cousin and son-in-law of Muhammad, was recognized as caliph by the rebels and the inhabitants of Medina. In the consequent first Islamic civil war, Mu'awiya opposed Ali from his stronghold in Syria, fighting him to a stalemate at the Battle of Siffin in 657. In January 661 Ali was assassinated by a Kharijite, after which his son Hasan was recognized as his successor. In August, Mu'awiya, who had already been recognized as caliph by his partisans in Syria, led his army toward Kufa, the capital of Hasan and Ali in Iraq, and gained control over the rest of the Caliphate by securing a peace treaty with Hasan. The terms of the treaty stipulated that Mu'awiya would not nominate a successor. Although the treaty brought a temporary peace, no framework of succession was established.Mu'awiya was determined to install Yazid as his successor. The idea was scandalous to Muslims, as hereditary succession had no precedent in Islamic history—earlier caliphs had been elected either by popular support in Medina or by the consultation of the senior companions of Muhammad—and according to Islamic principles, the position of ruler was not the private property of a ruler to award to his descendants. It was also unacceptable by Arab custom, according to which the rulership should not pass from father to son but within the wider clan. According to the orientalist Bernard Lewis, the "only precedents available to Mu'āwiya from Islamic history were election and civil war. The former was unworkable; the latter had obvious drawbacks." Mu'awiya passed over his eldest son Abd Allah, who was from his Qurayshite wife, perhaps due to the stronger support Yazid had in Syria because of his Kalbite parentage. The Banu Kalb was dominant in southern Syria and led the larger tribal confederation of Quda'a. The Quda'a were established in Syria long before Islam and had acquired significant military experience and familiarity with hierarchical order under the Byzantines, as opposed to the more free-spirited tribesmen of Arabia and Iraq. Northern Syria, on the other hand, was dominated by the tribal confederation of Qays, which had immigrated there during Mu'awiya's reign, and resented the privileged position of the Kalb in the Umayyad court. By appointing Yazid to lead campaigns against the Byzantines, Mu'awiya may have sought to foster support for Yazid from the northern tribesmen. The policy had limited success as the Qays opposed the nomination of Yazid, at least in the beginning, for he was "the son of a Kalbi woman". In the Hejaz, Yazid had support among his Umayyad kinsmen, but there were other members of the Hejazi nobility whose approval was important. By appointing Yazid to lead the hajj rituals there, Mu'awiya may have hoped to enlist support for Yazid's succession and elevate his status as a Muslim leader. According to Abu al-Faraj al-Isfahani, Mu'awiya had also employed poets to influence public opinion in favour of Yazid's succession.
According to the account of Ibn Athir, Mu'awiya summoned a of influential men from all of the provinces to his capital, Damascus, in 676 and won their support through flattery, bribes, and threats. He then ordered his Umayyad kinsman Marwan ibn al-Hakam, the governor of Medina, to inform its people of his decision. Marwan faced resistance, especially from Ali's son and Muhammad's grandson Husayn, and Abd Allah ibn al-Zubayr, Abd Allah ibn Umar, and Abd al-Rahman ibn Abi Bakr, all sons of prominent companions of Muhammad, who, by virtue of their descent, could also lay claim to the caliphal office. Mu'awiya went to Medina and pressed the four dissenters to accede, but they fled to Mecca. He followed and threatened some of them with death, but to no avail. Nonetheless, he was successful in convincing the people of Mecca that the four had pledged their allegiance, and received the Meccans' allegiance for Yazid. On his way back to Damascus, he secured allegiance from the people of Medina. General recognition of the nomination thus forced Yazid's opponents into silence. The orientalist Julius Wellhausen doubted the story, holding that the reports of the nomination's rejection by prominent Medinese were a back-projection of the events that followed Mu'awiya's death. A similar opinion is held by the historian Andrew Marsham. According to the account of al-Tabari, Mu'awiya announced the nomination in 676 and only received delegations from the Iraqi garrison town of Basra, which pledged allegiance to Yazid in Damascus in 679 or 680. According to al-Ya'qubi, Mu'awiya demanded allegiance for Yazid on the occasion of the Hajj. All, except the four prominent Muslims mentioned above, complied. No force was used against them. In any case, Mu'awiya arranged a general recognition for Yazid's succession before his death.
