Battle of Sardarabad Day is observed in Armenia on May 26 each year, commemorating the significant Battle of Sardarabad that occurred from May 21 to May 28 in 1918. This battle was a crucial event in Armenian history, marking a decisive victory for Armenian forces against the advancing Ottoman Empire during World War I. The backdrop of the battle involved the withdrawal of Russian troops following the Bolshevik Revolution, which left Armenia vulnerable after the Armenian Genocide in 1915 had already decimated its population. The victory at Sardarabad not only halted the Ottoman advance but also prevented further genocide and set the stage for the declaration of the Republic of Armenia on May 28, 1918. Each year, Armenians honor this day to remember the sacrifices made during the battle and to celebrate their national identity.
