In 1945, Red Army soldiers from the USSR freed thousands of prisoners from the Nazi regime's largest concentration camp at Auschwitz in Poland. Between 1940 and 1945, it is estimated that between 1,100,000 and 1,500,000 people died at the camp, with many being killed in gas chambers. The majority of the victims were Jews, but many other people were killed as well, including Poles, Gypsies, Soviet prisoners of war and tens of thousands of men and women who were killed because they were gay.
