The First Fitna 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.

Ali ibn Abi Talib, the fourth Rashidun caliph and the first Shia Imam, was assassinated during the morning prayer on 28 January 661 CE, equivalent to 19 Ramadan 40 AH. He died of his wounds about two days after the Kharijite dissident Ibn Muljim struck him over his head with a poison-coated sword at the Great Mosque of Kufa, located in Kufa, in present-day Iraq. He was about sixty-two years of age at the time of his death.
