Nazi concentration camps were death camps and forced labour camps operated by Nazi Germany during the Second World War. There were 27 main camps and at least 1,100 smaller camps in Nazi Germany and the territories it occupied.[1]
The five Nazi death camps were Chełmno, Belzec, Sobibor, Treblinka, and Auschwitz-Birkenau. Around 2.7 million Jews were murdered in these five camps.[2]
In other concentration camps, labor camps, and ghettos, the Nazis murdered an additional 800,000 to 1,000,000 Jews.[2]
Half a million non-Jews were also murdered in Nazi concentration camps, including 5,000 to 10,000 LGBT people.[3]
The camps were a key part of the Holocaust and Adolf Hitler's Final Solution.
