Cause

In 1939, Nazi Germany invaded and occupied Poland, bringing with it anti-Jewish ideology and policy. Jews were immediately subjected to violence, forced labor, and confinement. After Germany invaded the Soviet Union in 1941, Nazi leadership escalated to systematic extermination, establishing dedicated killing facilities on Polish soil.

Event

Under German occupation, Polish Jews were concentrated into ghettos, robbed of property, and deported to extermination camps including Chełmno, Bełżec, Sobibór, Treblinka, and Auschwitz. Mass shootings, gas chambers, and brutal ghetto liquidations between 1942 and 1944 killed more than three million Polish Jews, representing 90 percent of Poland's prewar Jewish population.

Consequence

After liberation, Jewish survivors faced difficulty reclaiming property and rebuilding lives. Postwar violence, including the Kielce pogrom, drove many survivors to flee to displaced persons camps in Allied-occupied Germany. The destruction of Polish Jewry eliminated one of the world's largest Jewish communities and permanently transformed Poland's demographic and cultural composition.
