Bloody Aban (Aban 24, 1398 Jalali) marks a significant day during the nationwide protests in Iran that began after a sudden increase in gasoline prices. On this day, widespread demonstrations erupted across many Iranian cities, and security forces responded with forceful measures to disperse the crowds. Reports indicate that hundreds of people were killed and thousands arrested. This event is considered a turning point in contemporary Iranian history and drew widespread reactions both inside and outside the country. A notable feature of this period was the extensive internet shutdown across Iran for several days, which severely restricted communication with the outside world. Families of victims and detainees continue to seek clarity about the fate of their loved ones. Bloody Aban remains a symbol of popular protest and the severe response by security forces in the collective memory of Iranian society. In subsequent years, some groups and activists have commemorated this day in remembrance of those killed and detained. The inclusion of this date in event calendars was due to its broad scope and deep impact on Iranian society, and it is often marked by recollections and eyewitness accounts.
