The April 9 tragedy (also known as The massacre of Tbilisi or Tbilisi tragedy) refers to the events in Tbilisi, Georgian Soviet Socialist Republic, on April 9, 1989, when an anti-Soviet, pro-independence demonstration was crushed 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, romanized: erovnuli ertianobis dghe), an annual public holiday.
