The Battle of Qbaada took place in today's Krasnaya Polyana on 2 June [O.S. 21 May] 1864. It is widely accepted as the final military engagement of the Russo-Circassian War, as the Circassian people could no longer continue to resist the invading Imperial Russian Army. A significant development in the wider Caucasian War, it was after the Battle of Qbaada that the Russian Empire annexed Circassia and initiated the Circassian genocide, in which 95% to 97% of the country's population was ethnically cleansed, leading to the creation of the Circassian diaspora.
