Most of the survivors in the DP camp at Bergen Belsen were young people. They found themselves entirely alone, having lost their parents, spouses, children and siblings during the Holocaust. They commonly chose to establish a feeling of normality and fight despair by marrying in the DP camp. During the first year after liberation, in the Bergen Belden DP camp, there were often six weddings a day, and up to fifty weddings a week. During 1946, there were 1,070 weddings at Bergen Belsen.
The camp included an administration building that contained offices for the Gestapo trial commissioner, SS authorities, the camp leader and his deputies. These administration offices consisted of large storage rooms for the personal belongings of prisoners, the bunker, roll-call square where guards would also inflict punishment on prisoners (especially those who tried to escape), the canteen where prisoners served SS men with cigarettes and food, the museum containing plaster images of prisoners who suffered from bodily defects, the camp office, the library, the barracks, and the infirmary, which was staffed by prisoners who had previously held occupations such as physicians or army surgeons.
Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million. Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories. Of Poland's 3.3 million Jews, about 90 percent were killed. Many more died in the ghettos of Poland before they could be deported. The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews. At Auschwitz-Birkenau the Jewish death toll was 1.1 million; Treblinka 870,000–925,000; Bełżec 434,000–600,000; Chełmno 152,000–320,000; Sobibór 170,000–250,000; and Majdanek 79,000.
The camp was liberated on April 15, 1945, by the British 11th Armoured Division. The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill, and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied. The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
