From 1795 until the Russian Revolution of 1917, Berestechko was part of Volhynian Governorate of the Russian Empire. Following the 1917 October Revolution in Russia, violent outbreaks occurred concerning disputes over the boundaries of each empire. Following an agreement between the two parties, from 1921 to 1939 Berestechko was part of Poland. In September 1939 it became part of the Union of Soviet Socialist Republics following the Soviet invasion of Poland, and became a town in January 1940.Берестечко // Большой энциклопедический словарь (в 2-х тт.). / редколл., гл. ред.

The Germans occupied Berestechko (then part of the Reichskommissariat Ukraine) from 23 June 1941 to April 1944, during which they forced all Jews in the town to live in a ghetto, and eventually executed them in 1942. A witness to the execution in the town stated, "The Jews dug their own pits, accompanied by ten requisitioned Ukrainians. People climbed on trees to watch the execution in spite of the ban. The Germans shot them so that they fell down into the pit." Out of the six present in the town, only one of them remained standing following the Nazism occupation. During 1943 the town became a refuge for Poles fleeing the Volyn massacre, and the Germans formed a Schutzmannschaft with several Poles to help defend against the Ukrainian Insurgent Army. The town church was attacked by the UPA on 30 December 1943, but the UPA were pushed back. The Poles would eventually leave the town for other nations, or to be deported off to concentration camps. On 17 January 1944, the Germans left the town.
After the end of the war, the town was rebuilt and in 1946 it was electrified. By 1950, a Watermill, a sawmill and several schools were in operation, and by 1968 a brick factory, food processing plant, and Zootechnics school were also established. As of 1989, the food industry remained the basis of the economy.
Following the dissolution of the Soviet Union the town became part of Ukraine.
