Over 1.1 million people, primarily Jews along with Poles, Soviets, Roma, and others, died at the Auschwitz concentration camp in Poland between 1940-1945, making it the largest Nazi camp and site of more deaths than the combined British and American losses of WWII; the camp operated experiments, hard labor, and mass killings through gas chambers and other means on prisoners who were categorized by colored triangles on their uniforms.
