The Circassian Day of Mourning is observed by the Circassian diaspora every year on 21 May to commemorate all those who were killed in and displaced by the Circassian genocide, which took place in the final stages of the Russian invasion of Circassia. It is known in Russia as the Day of Remembrance for the Victims of the Caucasus War, because the Russian government does not recognize the events as a genocide. On 21 May 1864, the Russian general Pavel Grabbe held a military parade in what is now Krasnaya Polyana following his troops' victory in the Battle of Qbaada; it was also on this day that Circassia was annexed by the Russian Empire, which then launched a campaign to empty the region of the native Circassian people.
