Kars Oblast
After the October Revolution of 1917 and the disintegration of Russian Empire, the lands of Kars Oblast were controlled for a short while by First Republic of Armenia and, in its northeastern part, by the Democratic Republic of Georgia. Eventually, Turkish forces recovered the region, leading to a formation of an unrecognized provisional government, before the lands gained by the First Republic of Armenia were maintained. Incorporation of most of the lands of the former Kars Oblast into Turkey was confirmed by the borders determined in the Treaty of Kars (1921), signed by proclaimed Turkish Government, Armenia SSR, Azerbaijan SSR and Georgia SSR.
