The 18 Tir 1378 Student Uprising began on Tir 18, 1378, with widespread student protests in Tehran and several other cities in Iran. The events were triggered by an attack on the University of Tehran dormitories following student demonstrations against the closure of a reformist newspaper. Security forces and plainclothes groups entered student residences, resulting in violent confrontations with students. In the days following Tir 18, the protests spread to the streets around the University of Tehran and to other cities. Reports indicate that hundreds were arrested and at least one person was killed. This event is considered one of the most significant student protests in Iran since the 1979 revolution, leaving a notable impact on the country’s political and social climate. The 18 Tir 1378 Student Uprising remains a symbol of civil protest and student demands in contemporary Iranian history. This observance was added to the unofficial calendar of some groups following the events of Tir 1378 and decisions by authorities at the time, and is mainly commemorated by gatherings and memorial events at universities.
