Iran, depicting the captives in the court of Yazid|261x261px Ali was himself elected caliph in 656, and later assassinated in his
de-facto capital
Kufa in January 661. Soon after Ali's death, his eldest son
Hasan was elected caliph in Kufa, but later abdicated in favor of
Mu'awiya () in August 661. The
peace treaty between Hasan and Mu'awiya stipulated that the latter should not appoint a successor. Hasan kept aloof from politics after his abdication in compliance with the peace treaty, but was poisoned and killed in 669, most likely at the instigation of Mu'awiya, who thus paved the way for the succession of his son
Yazid (). Hasan was then succeeded as the head of Muhammad's family by his brother
Husayn, who nevertheless upheld the treaty with Mu'awiya. Mu'awiya designated his son Yazid as his successor in 676, in violation of his earlier agreement with Hasan. Yazid is often remembered by Muslim historians as a debaucher who openly violated the Islamic norms, and his nomination was met with resistance from the sons of Muhammad's prominent companions, including Husayn ibn Ali. On Mu'awiya's death and Yazid's succession in 680, the latter instructed the governor of Medina to secure Husayn's pledge of allegiance by force. Husayn immediately left his hometown
Medina for
Mecca at night to avoid recognizing Yazid as the caliph. After receiving letters of support from some Kufans, whose intentions were confirmed by his envoy, Husayn later left Mecca for Kufa, accompanied by some relatives and supporters, including Zaynab and Umm Kulthum. On their way to Kufa, Husayn's small caravan was intercepted by Yazid's army and forced to camp in the desert land of
Karbala on 2 October 680 away from water and fortifications. The promised Kufan support did not materialize as the new governor of Kufa killed the envoy of Husayn and intimidated Kufan tribal chiefs. Having been surrounded for some days and deprived of the drinking water of the nearby
Euphrates river, Husayn was later killed on 10 October 680, alongside most of his male relatives and his small retinue, in the
Battle of Karbala against the army of the
Umayyad caliph Yazid ibn Mu'awiya (). After the battle, the women and children in Husayn's camp were taken prisoner and marched first to Kufa and later to the capital
Damascus in
Syria. Yazid eventually freed the captives, and they returned to Medina. The Muslim historian
Ibn Abi Tahir Tayfur () records two speeches about Karbala in his , which is an anthology of eloquent speeches by women
. He attributes one of the two speeches to Umm Kulthum in the market of Kufa, and the other to her sister Zaynab in the court of Yazid in Damascus. Most Shia authors, however, have later attributed both sermons to Zaynab, which the Islamicist
T. Qutbuddin considers highly likely. Concerning the first sermon, Ibn Tayfur writes that the Kufans wailed and wept when they saw Muhammad's family in captivity. Umm Kulthum (or Zaynab) then addressed the crowd and chastised them for their role in Husayn's death and recounted the events of Karbala. ==See also==
