On this day, Octobe 13, 1921 - the Soviet republics of Russia, Armenia, Azerbaijan, and Georgia sign the Treaty of Kars with the Grand National Assembly of Turkey to establish the contemporary borders between Turkey and the South Caucasus states.
Since the dissolution of the Soviet Union in 1991, the governments of Turkey, Georgia, and Azerbaijan have accepted the Kars treaty. But in contrast with this the Armenian position is different, based on the announcements of Armenian Government officials as well as the absence of any such ratification or decisions. The Armenian Declaration of Independence and Armenian Constitution call Turkey's eastern provinces Western Armenia. Armenia does not clearly recognize Turkey's national borders as defined in the Kars Treaty.
