In the 15th century, the area came under the control of the 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.
Thousands of Poles, especially retired Polish officers and intelligentsia were deported to Siberia and other areas in the depths of the Soviet Union.
A high proportion of these deportees died in the extreme conditions of Soviet labour camps and most were never able to return to Volyn again.
Partisans were involved in the Rail War against German supply lines and were known for their efficiency in gathering intelligence and for sabotage.
Once they became disillusioned with the Nazi program, they independently began to target all non-Ukrainians (Poles, Jews, Russians, among others) for extermination.
Most Poles who remained in the eastern region were forced to leave to the Recovered Territories of western Poland (the former easternmost provinces of Germany) whose German population had been expelled in accordance with the Potsdam Agreement.
