The world mourns for victims of the Holocaust, an infamous genocide in which approximately six million Jews were killed by the Nazi regime and its collaborators.Some historians use a definition of the Holocaust that includes the additional five million non-Jewish victims of Nazi mass murders (Soviet POWs, Poles, Gypsies, homosexual men and people with disabilities and terminal diseases), bringing the total to approximately eleven million. Killings took place throughout Nazi Germany and German-occupied territories.
Since 2005, the international community has been commemorating the Holocaust victims on January 27. On this day in 1945, the Soviet army released prisoners of German concentration camp Auschwitz-Birkenau (now Oświęcim, Poland). By various estimates, up to 4 million people died there. Historians failed to tell the actual number of victims, because many important documents from the camp were destroyed.
In 1947, a museum in memory of the Holocaust victims was opened on the camp’s territory; later it was included into the UNESCO World Heritage List.
