First Fitna in the context of "Marwanids (clan)"

The Umayyad Caliphate or Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the clan. The Umayyad family established dynastic, hereditary rule with Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of area. The dynasty was toppled by the Abbasids in 750. Survivors of the dynasty established themselves in Córdoba which, in the form of an emirate and then a caliphate, became a world center of science, medicine, philosophy and invention during the Islamic Golden Age.

The Umayyad dynasty (Arabic: بَنُو أُمَيَّةَ, romanized: Banū Umayya, lit. 'Sons of Umayya'), or the Umayyads (Arabic: الأمويون, romanized: al-Umawiyyūn) was an Arab clan within the Quraysh tribe who were the ruling family of the Umayyad Caliphate in 661–750 and the Emirate and later Caliphate of Córdoba in 756–1031.

In the pre-Islamic period, the Umayyads were a prominent clan of the Meccan tribe of Quraysh, descended from Umayya ibn Abd Shams. Despite staunch opposition to the Islamic prophet Muhammad, the Umayyads embraced Islam before the former's death in 632. Uthman ibn Affan, an early companion of Muhammad from the Umayyad clan, was the third Rashidun caliph, ruling in 644–656, while other members held various governorships. This included Mu'awiya ibn Abi Sufyan, the long-time governor of the Levant, who opposed the fourth Rashidun caliph Ali ibn Abi Talib in the First Muslim Civil War (656–661) and afterwards founded the Umayyad Caliphate with its capital in Damascus. This marked the beginning of the Umayyad dynasty, the first hereditary dynasty in the history of Islam, and the only one to rule over the entire Islamic world of its time. Umayyad authority was challenged in the Second Muslim Civil War, during which the Sufyanid line of Mu'awiya (which includes only the three first Umayyad caliphs) was replaced in 684 by Marwan I, who founded the Marwanid line of Umayyad caliphs, which restored the dynasty's rule over the Caliphate and remained so until the fall of the Caliphate of Córdoba.

The Second Fitna was the second civil war in the Islamic community during the early Umayyad Caliphate. It followed the death of the first Umayyad caliph Mu'awiya I in 680, and lasted for about twelve years. The war involved the defeat of three main challenges to the authority of the Umayyad dynasty, the first by Husayn ibn Ali, as well as his supporters including Sulayman ibn Surad and Mukhtar al-Thaqafi who rallied to avenge his death in Iraq, the second by Abd Allah ibn al-Zubayr who proclaimed himself caliph in Mecca and Medina and would be nominally recognized throughout most of the Caliphate, and the Kharijites who took over central Arabia and southern Iraq and Persia.

The roots of the civil war go back to the First Fitna. After the assassination of the third Rashidun caliph Uthman, the Islamic community experienced its first civil war over the immediate question of retribution for his murder. Following the assassination of the fourth Rashidun caliph Ali in 661 and the abdication of his successor Hasan the same year, Mu'awiya became the sole ruler of the caliphate. Mu'awiya's unprecedented decision to nominate his son Yazid as his heir sparked opposition, and tensions soared after Mu'awiya's death. Husayn ibn Ali was invited by the pro-Alids of Kufa to overthrow the Umayyads but was killed with his small company en route to Kufa at the Battle of Karbala in October 680. Yazid's army suppressed anti-government rebels in Medina in August 683 and subsequently besieged Mecca, where Ibn al-Zubayr had established himself in opposition to Yazid. After Yazid died in November the siege was abandoned, and Umayyad authority would soon collapse throughout the caliphate following the death of his son except in parts of Syria where Marwan I was proclaimed caliph; most provinces recognized Ibn al-Zubayr as caliph. A series of pro-Alid movements demanding to avenge Husayn's death emerged in Kufa, beginning with Ibn Surad's Penitents movement, which was crushed by the Umayyads at the Battle of Ayn al-Warda in January 685. Kufa was then taken over by Mukhtar, who rallied Husayn's supporters and the disenfranchised mawali to his cause. Though his forces routed a large Umayyad army at the Battle of Khazir in August 686, Mukhtar and his supporters were slain by the Zubayrids in April 687 following a series of battles. Under the leadership of Marwan, the Umayyads would consolidate their power over Syria and retake Egypt from the Zubayrids, and under his successor Abd al-Malik ibn Marwan, the Umayyads would reconquer Iraq after defeating the Zubayrids at the Battle of Maskin in 691 and would reassert their control over the Caliphate after killing Ibn al-Zubayr in the second siege of Mecca in 692, while their general Al-Hajjaj ibn Yusuf would suppress the Kharijites in the years afterwards.

Marwan ibn al-Hakam ibn Abi al-As ibn Umayya (Arabic: مروان بن الحكم بن أبي العاص بن أمية, romanized: Marwān ibn al-Ḥakam ibn Abī al-ʿĀṣ ibn Umayya; 623 or 626 – April/May 685), commonly known as Marwan I, was the fourth Umayyad caliph, ruling for less than a year in 684–685. He founded the Marwanid ruling house of the Umayyad dynasty, which replaced the Sufyanid house after its collapse in the Second Fitna and remained in power until 750.

During the reign of his cousin, the third Rashidun caliph Uthman (r. 644–656), Marwan took part in a military campaign against the Byzantine Exarchate of Africa (in central North Africa), where he acquired significant war spoils. He also served as Uthman's governor in Fars (southwestern Iran) before becoming the caliph's katib (secretary or scribe). He was wounded fighting the rebel siege of Uthman's house, in which the caliph was slain. In the ensuing civil war between the fourth Rashidun caliph Ali (r. 656–661) and the largely Qurayshite partisans of Aisha, Marwan sided with the latter at the Battle of the Camel. Marwan later served as governor of Medina under his distant kinsman Caliph Mu'awiya I (r. 661–680), founder of the Umayyad Caliphate. During the reign of Mu'awiya's son and successor Yazid I (r. 680–683), Marwan organized the defense of the Umayyad realm in the Hejaz (western Arabia) against the local opposition which included prominent companions as well as Muhammad’s own clan, the Bani Hashim, who revolted under the banner of Muhammad’s grandson, Husayn ibn Ali. After Yazid died in November 683, the Mecca-based rebel and sahabi Abd Allah ibn al-Zubayr declared himself caliph and expelled Marwan, who took refuge in Syria, the center of Umayyad rule. With the death of the last Sufyanid caliph Mu'awiya II in 684, Marwan, encouraged by the ex-governor of Iraq Ubayd Allah ibn Ziyad, volunteered his candidacy for the caliphate during a summit of pro-Umayyad tribes in Jabiya. The tribal nobility, led by Ibn Bahdal of the Banu Kalb, elected Marwan and together they defeated the pro-Zubayrid Qays tribes at the Battle of Marj Rahit in August of that year.

Constantinople was besieged by the Arabs in 674–678, in what was the first culmination of the Umayyad Caliphate's expansionist strategy against the Byzantine Empire. Caliph Mu'awiya I, who had emerged in 661 as the ruler of the Muslim Arab empire following a civil war, renewed aggressive warfare against Byzantium after a lapse of some years and hoped to deliver a lethal blow by capturing the Byzantine capital of Constantinople.

As reported by the Byzantine chronicler Theophanes the Confessor, the Arab attack was methodical: in 672–673 Arab fleets secured bases along the coasts of Asia Minor and then installed a loose blockade around Constantinople. They used the peninsula of Cyzicus near the city as a base to spend the winter and returned every spring to launch attacks against the city's fortifications. Finally the Byzantines, under Emperor Constantine IV, destroyed the Arab navy using a new invention, the liquid incendiary substance known as Greek fire. The Byzantines also defeated the Arab land army in Asia Minor, forcing them to lift the siege. The Byzantine victory was of major importance for the survival of the Byzantine state, as the Arab threat receded for a time. A peace treaty was signed soon after, and following the outbreak of another Muslim civil war, the Byzantines even experienced a brief period of ascendancy over the Caliphate. The siege was arguably the first major Arab defeat in 50 years of expansion and temporarily stabilized the Byzantine Empire after decades of war and defeats.

The Umayyad Caliphate or the Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the Umayyad clan. The Umayyad family established a dynasty with hereditary rule under Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, who came from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered an area of 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of size. The dynasty was overthrown by the Abbasids in 750. Survivors of the dynasty established an emirate and then a caliphate in Córdoba, with Cordoba becoming a major center of science, medicine, philosophy and invention during the Islamic Golden Age.

The Kharijites (Arabic: الخوارج, romanized: al-Khawārij, singular Arabic: خارجي, romanized: khārijī) were an Islamic sect which emerged during the First Fitna (656–661). The first Kharijites were supporters of Ali who rebelled against his acceptance of arbitration talks to settle the conflict with his challenger, Mu'awiya, at the Battle of Siffin in 657. They asserted that "judgment belongs to God alone", which became their motto, and that rebels such as Mu'awiya had to be fought and overcome according to Qur'anic injunctions. Ali defeated the Kharijites at the Battle of Nahrawan in 658, but their insurrection continued. Ali was assassinated in 661 by a Kharijite dissident seeking revenge for the defeat at Nahrawan.

After Mu'awiya established the Umayyad Caliphate in 661, his governors kept the Kharijites in check. The power vacuum caused by the Second Fitna (680–692) allowed for the resumption of the Kharijites' anti-government rebellion, and the Kharijite factions of the Azariqa and Najdat came to control large areas in Persia and Arabia. Internal disputes and fragmentation weakened them considerably before their defeat by the Umayyads in 696–699. In the 740s, large-scale Kharijite rebellions broke out across the caliphate, but all were eventually suppressed. Although the Kharijite revolts continued into the Abbasid Caliphate (750–1258), the most militant Kharijite groups were gradually eliminated. They were replaced by the non-activist Ibadiyya, who survive to this day in Oman and some parts of North Africa. They, however, deny any links with the Kharijites of the Second Muslim Civil War and beyond, condemning them as extremists.

Hasan ibn Ali (Arabic: الحسن ابن علي, romanized: al-Ḥasan ibn ʿAlī; c. 625 – 2 April 670) was an Alid political and religious leader. The eldest son of Ali and Fatima and a grandson of the Islamic prophet Muhammad, Hasan briefly ruled as caliph from January 661 until August 661. He is considered as the second Imam in Shia Islam, succeeding Ali and preceding his brother Husayn. As a grandson of the prophet, he is part of the ahl al-bayt and the ahl al-kisa, and also participated in the event of the mubahala.

During the caliphate of Ali (r. 656–661), Hasan accompanied him in the military campaigns of the First Fitna. Following Ali's assassination in January 661, Hasan was acknowledged caliph in Kufa. His sovereignty was not recognized by Mu'awiya ibn Abi Sufyan (r. 661–680), the governor of Syria, who led an army into Kufa while pressing Hasan for abdication in letters. In response, Hasan sent a vanguard under Ubayd Allah ibn al-Abbas to block Mu'awiya's advance until he arrived with the main army. Meanwhile, Hasan was severely wounded in an abortive assassination attempt by the Kharijites, a faction opposed to both Ali and Mu'awiya. This attack demoralised Hasan's army and led to widespread desertion. Ubayd Allah and most of his troops also defected after Mu'awiya bribed him. In August 661, Hasan signed a peace treaty with Mu'awiya on the condition that the latter should rule in compliance with the Quran and the Sunnah, a council should appoint his successor, and Hasan's supporters would receive amnesty. Hasan retired from politics and abdicated in Medina where he died either from illness or poisoning, though the early sources are nearly unanimous that he was poisoned. Mu'awiya is commonly viewed as the instigator in the murder of Hasan, which removed an obstacle to the succession of his son Yazid I (r. 680–683).
