Atrocity · 1941–1945
The Holocaust
Auschwitz-Birkenau, Oświęcim (Poland)
From 1941 to 1945 Nazi Germany and its collaborators systematically murdered around six million Jews, about two-thirds of Europe's Jewish population, in mass shootings across Eastern Europe and in the gas chambers of extermination camps in occupied Poland. At the Auschwitz complex, the deadliest killing centre, at least 1.1 million people were killed, about a million of them Jews, before Soviet troops liberated it on 27 January 1945.

Why it mattered
The Holocaust was state-sponsored mass murder on an unprecedented scale; the Nazi regime also killed Roma and Sinti, disabled people, Soviet prisoners of war and millions of other civilians.
