Львовско-Сандомирская операция
During the World War II the region was occupied by the Nazi Germany (see Operation Barbarossa). Along with Lviv, Drohobych and Tarnopil oblasts, it was reorganized on August 1, 1941 into Distrikt Galizien centered in Lemberg and annexed to the General Government. The area of the former Stanislav Oblast was divided into three kreis (counties): Kalusz, Stanislau, and Kolomea. On July 27, 1944 the region was liberated from the Nazi Germany by the Soviet Army (see Lvov–Sandomierz Offensive).
