The event marks the anniversary of the Battle of Karbala, when Imam Hussein ibn Ali, the grandson of Muhammad, was killed by the forces of the second Umayyad caliph. Family members accompanying him were killed or subjected to humiliation. The commemoration of this event during the yearly mourning season, with the Day of Ashura as the focal date, serves to define Shia communal identity. It is held in most of the cities of Iran include Jahrom.
Mourning of Muharram is a set of religious rituals observed by Shia Muslims during the month of Muharram, the first month of the Islamic calendar. These annual rituals commemorate the death of Husayn ibn Ali, grandson of the Islamic prophet Muhammad and the third Shia Imam. Husayn and his small retinue were slaughtered in the Battle of Karbala on 10 Al-Muharram 61 AH by the army of the Umayyad caliph Yazid I. Husayn's suffering and martyrdom became a symbol of sacrifice in the struggle for right against wrong, and for justice and truth against injustice and falsehood. He is a universal, borderless, interfaith and meta-religion symbol. Husayn and his companions are widely regarded as martyrs by all Muslims.
