West Ukrainian People's Republic
The WUPR emerged as a breakaway state amid the dissolution of Austria-Hungary, and in January 1919 nominally united with the Ukrainian People's Republic (UPR) as its autonomous Western Oblast. Poland had also claimed this territory, and by July occupied most of it and forced the West Ukrainian government into exile. When the UPR decided late the same year that it would trade the territory for an alliance with Poland against Soviet Russia, the exiled West Ukrainian government broke with the UPR. The exiled government continued its claim until it dissolved in 1923.
