Yazid ibn Mu'awiya ibn Abi Sufyan, commonly known as Yazid I, was the second caliph of the Umayyad Caliphate. He ruled from April 680 until his death in November 683. His appointment 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.
Muslim ibn ʿUqba al-Murrī (pre-622–683) was a general of the Umayyad Caliphate during the reigns of caliphs Mu'awiya I and his son and successor Yazid I. The latter assigned Muslim, a staunch loyalist who had distinguished himself at the Battle of Siffin, to be the commander of an expedition against the people of Medina for refusing to give Yazid the oath of allegiance. The victory of Muslim at the Battle of al-Harrah in 683 and the subsequent pillaging of Medina by his army was considered among the major injustices carried out by the Umayyads. Muslim died shortly after.
