The Armeno-Georgian War was a short border dispute that was fought in December 1918 between the newly independent Democratic Republic of Georgia and the First Republic of Armenia, largely over the control of former districts of the Tiflis Governorate, in Borchaly (Lori) and Akhalkalaki.

The Democratic Republic of Georgia was the first modern establishment of a republic of Georgia, which existed from May 1918 to February 1921. Recognized by all major European powers of the time, DRG was created in the wake of the Russian Revolution of 1917, which led to the collapse of the Russian Empire and allowed territories formerly under Russia's rule to assert independence. In contrast to Bolshevik Russia, DRG was governed by a moderate, multi-party political system led by the Georgian Social Democratic Party (Mensheviks).
