Poland occupied most of the Western Oblast's territory by July, and the UPR recognized the territory as part of Poland in April 1920. In September of the same year, the Ministry of Internal Affairs of the UPR, then in exile in Tarnów, stated in a letter that the Ukrainian State citizenship law remained valid. By November, the UPR had decisively lost the last of its territory, which was divided in 1921 between Poland, Soviet Russia, and the Ukrainian SSR.
