The Mourning of Muharram (also known as the Remembrance of Muharram or Muharram Observances) is a set of rituals associated with mainly Shia Muslims; however, some Muslims from other sects, as well as some non-Muslims, also take part in the remembrance. The commemoration falls 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.
