In Muslim countries such as Afghanistan, Iran, Iraq, Turkey, Azerbaijan, Pakistan, Lebanon, and Bahrain, the Commemoration of Husayn ibn Ali has become a national holiday.
The event is mourned differs between different branches of Shia and different ethnic groups. The event is also observed by many Sunnis, but to a lesser extent, and as a time of remembrance, rather than mourning.
