20 May 1940

The first prisoners arrive at a newly built concentration camp at Auschwitz.

Auschwitz, also known as Auschwitz-Birkenau, opened in 1940 and was the largest of the Nazi concentration and death camps. Located in southern Poland, Auschwitz initially served as a detention center for political prisoners. However, it evolved into a network of camps where Jewish people and other perceived enemies of the Nazi state were exterminated, often in gas chambers, or used as slave labor. Some prisoners were also subjected to barbaric medical experiments led by Josef Mengele. During World War II, more than 1 million people, by some accounts, lost their lives at Auschwitz. In January 1945, with the Soviet army approaching, Nazi officials ordered the camp abandoned and sent an estimated 60,000 prisoners on a forced march to other locations. When the Soviets entered Auschwitz, they found thousands of emaciated detainees and piles of corpses left behind.

After the start of World War II, Adolf Hitler, the chancellor of Germany from 1933 to 1945, implemented a policy that came to be known as the “Final Solution.” Hitler was determined not just to isolate Jews in Germany and countries annexed by the Nazis, subjecting them to dehumanizing regulations and random acts of violence. Instead, he became convinced that his “Jewish problem” would be solved only with the elimination of every Jew in his domain, along with artists, educators, Romas, communists, homosexuals, the mentally and physically handicapped and others deemed unfit for survival in Nazi Germany.
