The Armenian National Congress (or Congress of Eastern Armenians[1][2]) was a political congress established to provide representation for the Armenians of Russia.[3][4][5] It first met at the Artistic Theatre in Tbilisi on 11 October [O.S. 28 September] 1917.[6][7][8][9][10] Its formation was prompted by the opportunities the Russian Revolution provided for Armenians (and other minority nationalities in Russia) towards the end of World War I.[4]
