The village was later renamed after Bolshevik captain [2] who committed his troops and the armoured train Vardan Zoravar to the May Uprising against the Dashnak government of Armenia in Aleksandropol (Gyumri)—He was imprisoned for several months until the Red Army executed two notable Dashnaks in Zangezur, thus prompting his execution in retaliation.
