1965 Yerevan demonstrations
On April 24, 1965, for the first time for any such demonstration in the entire Soviet Union, one million protesters held a 24-hour demonstration in front of the Opera House, and demanded that the Soviet Union government officially recognize the Armenian Genocide committed by the Young Turks in the Ottoman Empire, and build a memorial in Armenia's capital city of Yerevan to perpetuate the memory of the victims of the Armenian Genocide.
