The concentration camps, 1933-1945. The Nazis set up their first concentration camp, Dachau, in the wake of Hitlerâs takeover of power in 1933. By the end of the war, 22 main concentration camps were established, together with around 1,200 affiliate camps, Aussenkommandos, and thousands of smaller camps. In 1945, when Allied forces liberated the concentration camps at Dachau, Bergen-Belsen, Buchenwald, Sachsenhausen, Auschwitz and elsewhere, the world was shocked at the sight of images of dead bodies alongside half-dead people in these camps.
