Student activists around the world have also planned events for this day. One of the themes is "Empty Chairs", a homage to students absent from their seats. Over 70 students are in prison, over 100 have been expelled from school, and an unaccounted number have been banned from entering university and dormitory grounds.

December 7th marks the National Student Day in Iran. The origin of this day goes back to 1953 where Tehran University students were protesting Nixon's visit to Iran. The CIA had just staged a Coup in Iran, toppling the government of Mohammad Mosaddegh, the elected Prime Minister. On December 7th, military forces entered Tehran University grounds, opened fire on the protesters and killed 3 students.
