The newly established Republic of Armenia proclaimed on 28 May 1918, included the city of Alexandropol. On 10 May 1920, the local Bolshevik Armenians aided by the Muslim population, attempted a coup d'état in Alexandropol against the Dashnak government of Armenia. The uprising was suppressed by the Armenian government on May 14 and its leaders were executed. However, during another Turkish invasion, Turkish troops attacked Alexandropol and occupied the city on 7 November 1920. Armenia was forced to sign the Treaty of Alexandropol on December 3 to stop the Turkish advance towards Yerevan, however a concurrent Soviet invasion led to the fall of the Armenian government on December 2. The Turkish forces withdrew from Alexandropol after the Treaty of Kars was signed in October 1921 by the unrecognized Soviet and Turkish governments.
