World War II: The Soviet 322nd Rifle Division liberates the remaining inmates of Auschwitz-Birkenau.

The 322nd Rifle Division was a standard Red Army rifle division during World War II. It is most notable for liberating Auschwitz concentration camp as part of the 60th Army on January 27, 1945, in the course of the Vistula-Oder offensive. Prior to this the division also distinguished itself during the second liberation of Zhitomir on the last day of 1943. It received further distinctions for its service in western Ukraine and in Poland. Along with many other distinguished Soviet formations it was disbanded with the coming of peace.

On 27 January 1945, Auschwitz—a Nazi concentration camp and extermination camp in occupied Poland where more than a million people were murdered as part of the Nazis' "Final Solution" to the Jewish question—was liberated by the Soviet Red Army during the Vistula–Oder Offensive. Although most of the prisoners had been forced onto a death march, about 7,000 had been left behind. The Soviet soldiers attempted to help the survivors and were shocked at the scale of Nazi crimes. The date is recognized as International Holocaust Remembrance Day.

Auschwitz, also known as Oświęcim, was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers, Auschwitz III-Monowitz, a labour camp for the chemical conglomerate IG Farben, and dozens of subcamps. The camps became a major site of the Nazis' Final Solution to the Jewish question.
