Tarnopol Voivodeship
After the partitions of Poland, Monastyryska was annexed by the Habsburg Empire. It remained in the province of Galicia until November 1918. In the Second Polish Republic, it was part of Buchach County, Tarnopol Voivodeship. Following the Soviet Invasion of Poland (September 17, 1939), the town was annexed by the Soviet Union. Many Lemkos families came to Monastyryska after Operation Vistula.
