First Fitna

The First Fitna ( ar, فتنة مقتل عثمان, fitnat maqtal ʻUthmān, strife/sedition of the killing of Uthman) was the first civil war in the Islamic community. It led to the overthrow of the Rashidun Caliphate and the establishment of the Umayyad Caliphate. The civil war involved three main battles between the fourth Rashidun caliph, Ali, and the rebel groups.

The roots of the first civil war can be traced back to the assassination of the second caliph, Umar. Before he died from his wounds, Umar formed a six-member council which elected Uthman as the next caliph. During the final years of Uthman's caliphate, he was accused of nepotism and killed by rebels in 656. After Uthman's assassination, Ali was elected the fourth caliph. Aisha, Talha, and Zubayr revolted against Ali to depose him. The two parties fought the Battle of the Camel in December 656, from which Ali emerged victorious. Afterward, Mu'awiya, the incumbent governor of Syria, declared war on Ali ostensibly to avenge Uthman's death. The two parties fought the Battle of Siffin in July 657, which ended in a stalemate and arbitration. This arbitration was resented by the Kharijites, who declared Ali, Mu'awiya, and their followers infidels. Following Kharijite violence against civilians, Ali's forces crushed them in the Battle of Nahrawan. Soon after, Mu'awiya also seized control of Egypt with the aid of Amr ibn al-As.

In 661, Ali was assassinated by the Kharijite Abd al-Rahman ibn Muljam. After Ali's death, his heir Hasan was elected caliph and soon after attacked by Mu'awiya. The embattled Hasan concluded a peace treaty, acknowledging the rule of Mu'awiya, who subsequently founded the Umayyad Caliphate and ruled as its first caliph.

Background

Following Muhammad's death in 632, Abu Bakr became the leader of the Muslim community. After reasserting Muslim control over the dissident tribes of Arabia, he sent armies to fight against the empires of Byzantium and Sasanian Persia, initiating a wave of conquests which were continued by his successor Umar (). These battles brought about the near-total collapse of the Sasanians, and restricted the Byzantine Empire to Anatolia, North Africa, and its holdings in Europe. The conquests brought Muslims bounteous revenue and lands. In Iraq, the lands of the Persian crown and aristocracy were now in Muslim hands. These became state-administered communal property. The revenue was distributed among the conquering troops, who settled in Iraq. Umar also left provincial administration to regional governors, who ruled with considerable autonomy. Provincial surplus was spent on the Muslim settlers of the conquered territories rather than forwarded to the capital, Medina.

Uthman succeeded Umar upon the latter's assassination by a slave in 644. The new caliph's policies elicited discontent among the Muslim elite as well as accusations of nepotism. He began centralizing power by relying on his Umayyad relatives, who had long opposed Muhammad before converting to Islam in 630. His favor toward relatives was to the exclusion of other members of the Quraysh, who had enjoyed significant authority during the reign of his two predecessors. He appointed his kinsmen to all of the provincial governorships. Although Uthman continued Muslim expansion in Persia and Egypt, these conquests came to a halt by the later half of his reign. The influx of spoils slowed, magnifying economic issues that had previously been tempered by incoming revenue. This was coupled with Arab nomads' antipathy toward central authority, which had hitherto been superseded by the continued war effort. The continued migration of tribes from Arabia to the conquered territories also resulted in reduced payments from the revenue of the lands, which led to resentment among the earlier settlers. Early settlers also saw their status threatened by land grants in the conquered territories to prominent Qurayshites like Talha ibn Ubayd Allah and Zubayr ibn al-Awwam, as well as land acquisitions by late-arriving tribal chiefs, such as Ashath ibn Qays. These chiefs were given this territory in exchange for their lands in Arabia. Furthermore, Uthman took control of the crown lands of Iraq as state assets, and demanded that the provincial surplus be forwarded to the caliph. This interference in provincial affairs brought about widespread opposition to his rule, especially from Iraq and Egypt, where the majority of the conquering armies had settled.

Encouraged by the Medinese elite including prominent figures like Talha, Zubayr, Amr ibn al-As (a former governor of Egypt who Uthman deposed), and Muhammad's widow Aisha, the provincial opposition subsequently broadened into open rebellion. Dissidents from Egypt and Iraq marched on Medina, killing the caliph in June 656. Ali, Muhammad's cousin and son-in-law, was subsequently recognized caliph.

Battle of the Camel

Aisha, Talha, and Zubayr opposed Ali's succession and gathered in Mecca, where they demanded vengeance for Uthman's death and the election of a new caliph, presumably either Talha or Zubayr, through consultation. The rebels raised an army and captured Basra from Ali's governor, inflicting heavy casualties on his men, with the intention of strengthening their position. Ali sent his son Hasan to mobilize troops in Kufa. After Ali arrived in Kufa himself, the combined army marched to Basra.

The two armies met outside of Basra. After three days of failed negotiations, the battle began in the afternoon of 8 December 656 and lasted until the evening. Zubayr left the field without fighting. Likely for the dishonorable act of leaving his fellow Muslims behind in a civil war he caused, Zubayr was pursued and killed by the troops of al-Ahnaf bin Qays, a chief of the Banu Sa'd who had remained on the sidelines of the battle.. . Talha was killed by the Umayyad Marwan ibn al-Hakam.

With the deaths of Talha and Zubayr, the fate of the battle was sealed in favor of Ali. However, the fight continued until Ali's troops succeeded in killing Aisha's camel, which her forces had rallied around. From this camel, the battle received its name. After admonishing Aisha, Ali sent her back to Medina, escorted by her brother. Ali also announced a public pardon and set the prisoners free. This pardon was also extended to high-profile rebels, including Marwan, who soon joined with his Umayyad kinsman Mu'awiya ibn Abi Sufyan, the governor of Syria, as a senior advisor.. . .

Battle of Siffin

Shortly after assuming power, Ali moved to dismiss most of Uthman's governors whom he considered corrupt, including Mu'awiya, Uthman's cousin.. . Mu'awiya refused to step down and instead, through a representative, informed Ali that he would recognize the caliphate of Ali in return for the governorship of Syria and Egypt for life. Ali rejected this proposal. Earlier, he had also refused to temporarily confirm as governor Mu'awiya, whom Ali viewed as a contemptible man.

Mu'awiya now declared war on Ali on behalf of the Syrians, with the objectives of vengeance for Uthman's death, deposing Ali, and establishing a Syrian council to appoint the next caliph, presumably Mu'awiya. In a letter to him, Ali wrote that Mu'awiya was welcome to bring his case for Uthman to Ali's court of justice. Ali then challenged Mu'awiya to offer any evidence that would incriminate him in the murder of Uthman. He also challenged Mu'awiya to name any Syrian who would qualify for a council. Following Mu'awiya's declaration of war, Ali called a council of Islamic ruling elite which urged him to fight Mu'awiya.

The two armies met at Siffin, west of the Euphrates, early in the summer of 657 CE. There, the two sides negotiated for weeks. Notably, Mu'awiya repeated his proposition to recognize Ali in return for Syria and Egypt, which was rejected again. In turn, Ali challenged Mu'awiya to a one-on-one duel to settle the matters and avoid the bloodshed. This offer was declined by Mu'awiya. The negotiations failed on 18 July 657 and the two side readied for the battle. The main battle began on Wednesday, 26 July, and lasted for three or four days. By its last day, the balance had gradually moved in Ali's favor. Before noon, however, some of the Syrians raised copies of the Quran on their lances, shouting the same line, "Let the book of God be the judge between us." The fighting stopped.

Arbitration

Mu'awiya carried out the above strategy of appealing to the Quran when he was informed that his army could not win the battle. Faced with an appeal to their holy book, Ali's forces
