Volyn was once part of Kievan Rus' before becoming an independent local principality and an integral part of the Halych-Volynia, one of Kievan Rus' successor states. In the 15th century, the area came under the control of neighbouring Grand Duchy of Lithuania, in 1569 passing over to Poland and then in 1795, until World War I, to the Russian Empire where it was a part of the Volynskaya Guberniya. In the interwar period most of the territory, organized as Wołyń Voivodeship was under Polish control.

In 1939 when following the Molotov-Ribbentrop pact Poland was invaded and divided by Nazi Germany and the Soviet Union, Volyn joined the Soviet Ukraine, and on December 4, 1939 the oblast was organized.
