The Turkish–Armenian war (Armenian: Թուրք-հայկական պատերազմ), known in Turkey as the Eastern Front (Turkish: Doğu Cephesi) of the Turkish War of Independence, was a conflict in late 1920 between the First Republic of Armenia and the Turkish National Movement following the collapse of the Treaty of Sèvres. After the provisional government of Ahmet Tevfik Pasha failed to win support for ratification of the treaty, remnants of the Ottoman Army’s XV Corps under the command of Kâzım Karabekir attacked Armenian forces controlling the area surrounding Kars, eventually recapturing all territory previously ceded to the Ottoman Empire by Soviet Russia as part of the Treaty of Brest-Litovsk.
