In 1943, during the Volhynian Genocide, 96 ethnic Poles of Berezne were murdered by Ukrainian nationalists of the Ukrainian Insurgent Army. The first attack on the town took place in June 1943. Other attacks occurred in the second half of that year, and as a result Polish survivors fled to larger towns, such as Rowne. In June 1945 the remaining Poles were forced to leave Berezne in accordance with the Allied treaties.
