Anti-Jewish violence in Poland from 1944 to 1946 preceded and followed the end of World War II in Europe and influenced the postwar history of the Jews and Polish-Jewish relations. It occurred amid a period of violence and anarchy across the country caused by lawlessness and anti-communist resistance against the Soviet-backed communist takeover of Poland. The estimated number of Jewish victims varies, ranging up to 2,000. In 2021, Julian Kwiek published the first scientific register of incidents and victims of anti-Jewish violence in Poland from 1944 to 1947; according to Kwiek's calculations, the number of victims was 1,074 to 1,121. Jews constituted between two and three percent of the total number of victims of postwar violence in the country, including Polish Jews who managed to escape the Holocaust in territories of Poland annexed by the Soviet Union, and returned after the border changes imposed by the Allies at the Yalta Conference. Incidents ranged from individual attacks to pogroms.
