The liberation from concentration camps took place in 1944 and 1945. This moment was orchestrated by the Allied and Soviet forces that were taking over the land and restoring the freedom of those who had survived the cruel treatments of the concentration camps. This process was seen as one of the most important moments in the events of those times, as the faith in humanity was in a degrading stage. After the liberation process from the concentration camps, many new information surfaced about the practices and treatments that took place in these. The horrid details that came up showed that the people who were kept in the concentration camps were tortured, subjected to experiments, starved and forced to work in difficult conditions.

One of the first concentration camps that was cleared by the forces was Majdanek, in 1944, located near Lublin, in Poland. In this camp, the prisoners were placed under forced labor and later on exterminated, in the period between 1941 and 1944. It is estimated that around 78,000 people were killed here. Auschwitz was the second of the liberated concentration camps, in 1945. This is one of the most well-known concentration camps, due to the fact that it included famous prisoners, books were written about it and the largest number of deaths was recorded here (approximately 1.1 million people). Auschwitz was a larger camp facility, which included multiple barracks, subcamps and other buildings. In addition to this, the torture practices here were deemed to be a lot crueller, as they also included medical experiments, especially done on children, and other killing methods. In 1945, several other concentration camps were liberated as follows: Buchenwald (by the American forces), Bergen-Belsen (by the British forces), Dachau (by the American forces), Ravensbruck (by the Soviet forces), Mauthausen (by the American forces) and Theresienstadt (by the Soviet forces).

All the concentration camps liberated still had people living in them. However, their lives were in danger due to the treatments they suffered, diseases caught and malnutritions. Several camps, that were not liberated, were later on destroyed by the Nazis, such as Treblinka, Sobibor and Belzec.
