Millions of Shiite Muslims make a pilgrimage every year to the Hussein ibn Ali shrine in Karbala, Iraq, to commemorate the battle in which the grandson of the Prophet Muhammad was killed. Under Saddam Hussein's rule, Arbaeen — meaning the “40th” day — commemorations were subdued. With the fall of Saddam and closer Iran-Iraq relations, Arbaeen pilgrimages have become important not only for millions of Iranian pilgrims but also for Iranian leaders who see the rise of the significance of the event with their own geopolitical rise.
At a meeting with the families of those who lost their lives fighting in Iraq and Syria — fighters whom Iran refers to as “defenders of the shrines” — Iran’s Supreme Leader Ayatollah Ali Khamenei stressed the importance of this group for the significance of Arbaeen today. Khamenei recounted the actions of the early believers who protected Ali's tomb and likened them to today’s defenders of the shrines.
