Second Fitna in the context of Battle of Ayn al-Warda

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.

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.

The Battle of Karbala (Arabic: مَعْرَكَة كَرْبَلَاء, romanized: Maʿrakat Karbalāʾ) was fought on 10 October 680 (10 Muharram in the year 61 AH of the Islamic calendar) between the army of the second Umayyad caliph Yazid I (r. 680–683) and a small army led by Husayn ibn Ali, the grandson of the Islamic prophet Muhammad, at Karbala, Sawad (modern-day southern Iraq).

Prior to his death, the Umayyad caliph Mu'awiya I (r. 661–680) had nominated his son Yazid as his successor. Yazid's nomination was contested by the sons of a few prominent companions of Muhammad, including Husayn, son of the fourth caliph Ali, and Abd Allah ibn al-Zubayr, son of Zubayr ibn al-Awwam. Upon Mu'awiya's death in 680, Yazid demanded allegiance from Husayn and other dissidents. Husayn did not give allegiance and traveled to Mecca. The people of Kufa, an Iraqi garrison town and the center of Ali's caliphate, were averse to the Syria-based Umayyad caliphs and had a long-standing attachment to the house of Ali. They proposed Husayn overthrow the Umayyads. On Husayn's way to Kufa with a retinue of about 70 men, his caravan was intercepted by a 1,000-strong army of the caliph at some distance from Kufa. He was forced to head north and encamp in the plain of Karbala on 2 October, where a larger Umayyad army of 4,000 arrived soon afterwards. Negotiations failed after the Umayyad governor Ubayd Allah ibn Ziyad refused Husayn safe passage without submitting to his authority, a condition declined by Husayn. Battle ensued on 10 October during which Husayn was killed along with most of his relatives and companions, while his surviving family members were taken prisoner. The battle was the start of the Second Fitna, during which the Iraqis organized two separate campaigns to avenge the death of Husayn; the first one by the Tawwabin and the other one by Mukhtar al-Thaqafi and his supporters.

Yazid ibn Mu'awiya ibn Abi Sufyan (c. 646 – 11 November 683), 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 (r. 661–680) 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 676 CE (56 AH) 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 (the Umayyad caliph Marwan I and his descendants).

Abd al-Malik ibn Marwan ibn al-Hakam (July/August 644 or June/July 647 – 9 October 705), was the fifth Umayyad caliph, ruling from April 685 until his death in October 705. A member of the first generation of born Muslims, his early life in Medina was occupied with religious pursuits. He held administrative and military posts under Caliph Mu'awiya I (r. 661–680), founder of the Umayyad Caliphate, and his own father, Caliph Marwan I (r. 684–685). By the time of Abd al-Malik's accession, Umayyad authority had collapsed across the Caliphate as a result of the Second Fitna and had been reconstituted in Syria and Egypt during his father's reign.

Following a failed invasion of Iraq in 686, Abd al-Malik focused on securing Syria before making further attempts to conquer the greater part of the Caliphate from his principal rival, the Mecca-based caliph Abd Allah ibn al-Zubayr. To that end, he concluded an unfavorable truce with the reinvigorated Byzantine Empire in 689, quashed a coup attempt in Damascus by his kinsman, al-Ashdaq, the following year, and reincorporated into the army the rebellious Qaysi tribes of the Jazira (Upper Mesopotamia) in 691. He then conquered Zubayrid Iraq and dispatched his general, al-Hajjaj ibn Yusuf, to Mecca where he killed Ibn al-Zubayr in late 692, thereby reuniting the Caliphate under Abd al-Malik's rule. The war with Byzantium resumed, resulting in Umayyad advances into Anatolia and Armenia, the destruction of Carthage and the recapture of Kairouan, the launchpad for the later conquests of western North Africa and the Iberian Peninsula, in 698. In the east, al-Hajjaj had become Abd al-Malik's viceroy and firmly established the caliph's authority in Iraq and Khurasan, stamping out opposition by the Kharijites and the Arab tribal nobility by 702. Abd al-Malik's final years were marked by a domestically peaceful and prosperous consolidation of power.

Sulayman ibn Surad al-Khuza'i (Arabic: سُلَيْمَان ٱبْن صُرَد ٱلْخُزَاعِيّ, romanized: Sulaymān ibn Ṣurad al-Khuzāʿī; died January 685) was a pro-Alid leader from Kufa, who led the Tawwabin movement during the Second Fitna to avenge the death of Husayn ibn Ali, a grandson of the Islamic prophet Muhammad. He had participated in battles during the First Fitna on the side of the fourth caliph Ali, although at occasions was disapproving of his decisions. After the death of Mu'awiya I, he was the most prominent of the Kufans who urged Ali's son Husayn to revolt. After the death of Husayn at the Battle of Karbala in 680, in which he failed to support Husayn, Ibn Surad and some other Alid partisans of Kufa sacrificed themselves in an attempt to avenge his death.

Al-Mukhtar ibn Abi Ubayd al-Thaqafi (Arabic: الْمُخْتَار ٱبْن أَبِي عُبَيْد الثَّقَفِيّ, romanized: al-Mukhtār ibn Abī ʿUbayd al-Thaqafī; c. 622 – 3 April 687) was an Arab pro-Alid revolutionary based in Kufa, who led a rebellion against the Umayyad Caliphate in 685 and ruled over most of Iraq for eighteen months during the Second Fitna.

Born in Ta'if, Mukhtar moved to Iraq at a young age and grew up in Kufa. Following the death of Husayn ibn Ali, a grandson of the Islamic prophet Muhammad, at the hands of the Umayyad army in the Battle of Karbala in 680, he allied with the rival caliph Abd Allah ibn al-Zubayr in Mecca, but the alliance was short-lived. Mukhtar returned to Kufa where he declared Muhammad ibn al-Hanafiyya, a son of caliph Ali (r. 656–661) and brother of Husayn, the mahdi and the imam, and called for the establishment of an Alid caliphate and retaliation for Husayn's killing. He took over Kufa in October 685, after expelling its Zubayrid governor, and later ordered the execution of those involved in the killing of Husayn. Hostile relations with Ibn al-Zubayr ultimately led to Mukhtar's death by the forces of the Zubayrid governor of Basra, Mus'ab ibn al-Zubayr, following a four-month siege.

Abd Allah ibn al-Zubayr ibn al-Awwam (May 624 – October/November 692) was the leader of a caliphate based in Mecca in opposition to the Umayyads during the Second Fitna from 683 until his death in 692.

The son of al-Zubayr ibn al-Awwam and Asma bint Abi Bakr, and grandson of the first Rashidun caliph Abu Bakr, Ibn al-Zubayr belonged to the Quraysh, the leading tribe of the nascent Muslim community, and was the first child born to the Muhajirun, Islam's earliest converts. As a youth, he participated in the early Muslim conquests alongside his father in Syria and Egypt, and later played a role in the Muslim conquests of North Africa and northern Iran in 647 and 650, respectively. During the First Fitna, he fought on the side of his aunt Aisha against the fourth Rashidun caliph Ali (r. 656–661). Though little is heard of Ibn al-Zubayr during the subsequent reign of the first Umayyad caliph Mu'awiya I (r. 661–680), it was known that he opposed the latter's designation of his son, Yazid I, as his successor. Ibn al-Zubayr, along with many of the Quraysh and the Ansar of Medina, the leading Muslim groups of the Hejaz (western Arabia), opposed the caliphate becoming an inheritable institution of the Umayyad dynasty.

The siege of Mecca in September–November 683 was one of the early battles of the Second Fitna. The city of Mecca was a sanctuary for Abd Allah ibn al-Zubayr, who was among the most prominent challengers to the hereditary succession to the Caliphate by Yazid I of the Umayyad dynasty. After nearby Medina, the other holy city of Islam, also rebelled against Yazid, the Umayyad ruler sent an army to subdue the Hejaz. The Umayyad army defeated the Medinans and took the city, but Mecca held out in a month-long siege, during which the Kaaba was damaged by fire. The siege ended when news came of Yazid's sudden death. The Umayyad commander, Husayn ibn Numayr al-Sakuni, after failing to induce Ibn al-Zubayr to return with him to Syria and be recognized as Caliph, departed with his forces. Ibn al-Zubayr remained in Mecca throughout the civil war, but he was nevertheless soon acknowledged as Caliph across most of the Muslim world. It was not until 692 that the Umayyads were able to send another army, which again besieged and captured Mecca, ending the civil war.

The Battle of Khazir (Arabic: يوم الخازر, romanized: Yawm Khāzir) took place in August 686 near the Khazir River in Mosul's eastern environs, in modern-day Iraq. The battle occurred during the Second Muslim Civil War and was part of the larger struggle for control of Iraq between the Syria-based Umayyad Caliphate, the Kufa-based pro-Alid forces of Mukhtar al-Thaqafi, and the Mecca-based caliphate of Abd Allah ibn al-Zubayr. It ended with the Umayyads being routed and the expansion of Mukhtar's rule into the region of Mosul.

The Muslim civil war left the Umayyad realm restricted to Damascus and its environs after most of their territories came under Ibn al-Zubayr's orbit. However, an Umayyad resurgence began with the accession of Caliph Marwan I, who dispatched an army led by Ubayd Allah ibn Ziyad to reconquer Iraq. This army's advance into Mosul precipitated the Battle of Khazir and its commander, Ubayd Allah, was an enemy of Mukhtar's pro-Alid partisans. Thus, Mukhtar quickly moved to halt the Umayyad advance, sending his Persian mawālī-dominated forces led by Ibrahim ibn al-Ashtar to confront the predominantly Syrian Arab army of the Umayyads. During the initial combat, part of Ibn al-Ashtar's forces were put to flight, but then regrouped under his command and charged against the Umayyad center. This resulted in heavy casualties on both sides and Ubayd Allah and several of his lieutenants were slain. The Umayyad commander Umayr ibn al-Hubab and his Sulaymi tribesmen deserted while the pro-Alids pursued the remaining Umayyad troops, scores of whom drowned in the Khazir River.

The Battle of Marj Rahit (Arabic: يوم مرج راهط, romanized: Yawm Marj Rāhiṭ) was one of the early battles of the Second Fitna. It was fought on 18 August 684 between the Kalb-dominated armies of the Yaman tribal confederation, supporting the Umayyads under Caliph Marwan I, and the Qays under al-Dahhak ibn Qays al-Fihri, who supported the Mecca-based Abdallah ibn al-Zubayr; the latter had proclaimed himself Caliph. The decisive Umayyad victory consolidated their power over Bilad al-Sham (the Islamic Levant), paving the way for their eventual victory in the war against Ibn al-Zubayr. However, it also left a bitter legacy of division and rivalry between the Qays and the Yaman, which would be a constant source of strife and instability for the remainder of the Umayyad Caliphate.

The Battle of Maskin (Arabic: معركة مسكن), also known as the Battle of Dayr al-Jathaliq (Arabic: معركة دير الجثاليق) from a nearby Nestorian monastery, was a decisive battle of the Second Fitna (680s-690s). It was fought in mid-October 691 near present-day Baghdad on the western bank of the river Tigris, between the army of the Umayyad caliph Abd al-Malik ibn Marwan and the forces of Mus'ab ibn al-Zubayr, governor of Iraq for his brother, the Mecca-based rival caliph Abd Allah ibn al-Zubayr.

When the battle started, most of Mus'ab's troops refused to fight, having secretly switched allegiance to Abd al-Malik, and Mus'ab's main commander, Ibrahim ibn al-Ashtar, was killed in action. Mus'ab was slain soon afterward, resulting in the Umayyads' victory and recapture of Iraq, which opened the way for the Umayyad reconquest of the Hejaz (western Arabia) in late 692.

The siege of Mecca (Arabic: حصار مكة) occurred at the end of the Second Fitna in 692 when the forces of the Umayyad caliph Abd al-Malik ibn Marwan besieged and defeated his rival, the caliph Abd Allah ibn al-Zubayr in his center of power, the Islamic holy city of Mecca.

After the death of Caliph Yazid in 683, Ibn al-Zubayr had been recognized as caliph in most of the provinces of the Caliphate, while the Umayyads, who had ruled the Caliphate since the end of the First Fitna, had been confined to their stronghold of Syria. There, the pro-Umayyad tribes elected Marwan ibn al-Hakam as caliph in 684; after his death in 685, his son and successor Abd al-Malik undertook the task of reasserting Umayyad authority across the Caliphate. After defeating his enemies in Syria and Iraq, he sent his general Hajjaj ibn Yusuf to Mecca to defeat Ibn al-Zubayr. To avoid bloodshed in the sanctuary, Hajjaj was ordered to besiege the city and starve out Ibn al-Zubayr. The siege started in March 692 and lasted for six to seven months. The city was bombarded with catapults and supplies were cut off, resulting in large scale desertions by the followers of Ibn al-Zubayr. He was killed along with his few remaining supporters in October 692. The siege brought an end to the decade-long civil war and the Caliphate was united under Abd al-Malik. The Ka'ba, which had been damaged by the bombardment, was rebuilt according to its original plan from the time of the Islamic prophet Muhammad.

The Dome of the Rock (Arabic: قبة الصخرة, romanized: Qubbat aṣ-Ṣaḵra) is an octagonal Islamic shrine at the center of the Al-Aqsa mosque compound on the Temple Mount in the Old City of Jerusalem. It is the world's oldest surviving work of Islamic architecture, the earliest archaeologically-attested religious structure to be built by a Muslim ruler and contains the earliest inscriptions proclaiming Islam and the prophet Muhammad.

Its initial construction was undertaken by the Umayyad Caliphate on the orders of Abd al-Malik during the Second Fitna in 691–692 CE, and it has since been situated on top of the site of the Second Jewish Temple (built in c. 516 BCE to replace the destroyed Solomon's Temple and rebuilt by Herod the Great), which was destroyed by the Romans in 70 CE. The original dome collapsed in 1015 and was rebuilt in 1022–23.
