Muharram
Muharram (Arabic: المحرّم) is the first month of the Islamic calendar. It is one of the four sacred months of the year in which fighting is prohibited.[1] Since the Islamic calendar is a lunar calendar, Muharram moves from year to year when compared with the Gregorian calendar.
Muharram is so called because it is unlawful to fight during this month, the word is derived from the word haraam, meaning "forbidden". It is held to be the most sacred of all the months, excluding Ramadan. Some Muslims fast during these days. The tenth day of Muharram is the Day of Ashura, which to Shia Muslims is part of the Mourning of Muharram.
Shias start the mourning from the 1st night of Muharram and continue for two months and eight days. However the last days are the most important since these were the days where Imam Hussein (P.B.U.H) and his family and followers (consisting of 72 people, including women, children and aged people) were killed by army of Yazid I at the Battle of Karbala on his orders, Surviving members of the family of Imam Hussein(P.B.U.H) and that of his followers were taken captive and marched to Damascus and imprisoned there.
