OSWIECIM, POLAND - JANUARY 27, 2020: A view of the former Auschwitz concentration camp operated by Nazi Germany during WWII. Over a million Jews, as well as Soviet and Polish prisoners, were killed in the camp's gas chambers to be burnt in crematoria. Auschwitz was liberated by the Soviet Red Army on 27 January 1945; in 1947, the Polish government founded the Auschwitz-Birkenau State Museum on the site of the camp, which in 1979 was inscribed on the UNESCO World Heritage Site List. In 2005, January 27 was named International Holocaust Remembrance Day by the General Assembly of the United Nations. Natalia Fedosenko/TASS (Photo by Natalia FedosenkoTASS via Getty Images)
