The Mourning of Muharram, Remembrance of Muharram, or Muharram Observances, is a set of rituals associated with Shia Islam, which takes place in Muharram, the first month of the Islamic calendar. Many of the events associated with the ritual take place in congregation halls known as Hussainia.
The event marks the anniversary of the Battle of Karbala when Imam Hussein ibn Ali, the grandson of the Islamic prophet Muhammad(PBUH), and a Shia Imam, was killed by the forces of the second Umayyad caliph Yazid I at Karbala. Family members, accompanying Hussein ibn Ali, were killed and brutally tortured. The commemoration of the event during yearly mourning season, from first of Muharram to twentieth of Safar with Ashura comprising the focal date, serves to define Shia communal identity. At present, Muharram Observances are carried out in many countries in the world as well as in Fars provice.
