Великолукская область
In the summer of 1941, during the World War II, the current area of Pskov Oblast was occupied by German troops. Most of it was not liberated until the summer of 1944. After the liberation, the administrative division of Soviet Union was considerably changed. On August 22, 1944, Velikiye Luki Oblast was established, with the center in Velikiye Luki, and on the following day, August 23, 1944, Pskov Oblast was established. In 1945, some areas were transferred from Estonian and Latvian Soviet Socialist Republics to Pskov Oblast and formed three districts, Pechorsky, Pytalovsky, and Kachanovsky Districts. Together, Pskov and Velikiye Luki Oblasts now contained all the areas which currently constitute Pskov Oblast. On October 2, 1957, Velikiye Luki Oblast was abolished and split between Pskov and Kalinin Oblasts. As of October 1957, Pskov Oblast also contained Kholmsky and Ploskoshsky Districts, which in July 1958 were transferred to Novgorod and Kalinin Oblasts, respectively.
