Islamic Revolutionary Guard Corps Day is observed in Iran on October 9 each year. This day honors the Islamic Revolutionary Guard Corps (IRGC), a branch of Iran’s Armed Forces established after the Islamic Revolution of 1979 to protect the country's Islamic Republic system. The IRGC is recognized for its role in the Iran-Iraq War and for training Hezbollah forces. The date of the celebration is significant as it commemorates Husayn ibn Ali, the third Shia Imam, who was killed in the Battle of Karbala on October 10, 680. The Iranian government views the IRGC as a representation of a Shiite army, and the day has been celebrated annually since 2002 to highlight the importance of the IRGC in maintaining the values of the Islamic Republic.
