9 April

The April 9 tragedy (also known as Tbilisi massacre or Tbilisi tragedy) refers to the events in Tbilisi, Georgian Soviet Socialist Republic, on April 9, 1989, when an anti-Soviet demonstration was dispersed by the Soviet Army, resulting in 21 deaths and hundreds of injuries. April 9 is now remembered as the Day of National Unity (Georgian: ეროვნული ერთიანობის დღე erovnuli ertianobis dghe), an annual public holiday.

In the evening of April 8, 1989, Colonel General Igor Rodionov, Commander of the Transcaucasus Military District, ordered his troops to mobilize. Moments before the attack by the Soviet forces, the Patriarch of Georgia Ilia IIaddressed the demonstrators asking them to leave Rustaveli Avenue and the vicinity of the government building due to the danger which accumulated during the day after appearance of Soviet tanks near the avenue. The demonstrators refused to disband even after the Patriarch's plea. The local Georgian militsiya (police) units were disarmed just before the operation.
On April 9, at 3:45 a.m., Soviet APCs and troops under General Igor Rodionov surrounded the demonstration area. Later, Rodionov claimed in his interview that groups of Georgian militants attacked unarmed soldiers with stones, metal chains and rods. The Soviet troops received an order from General Rodionov to disband and clear the avenue of demonstrators by any means necessary.
