Majdanek concentration camp was a Nazi concentration and extermination camp located near Lublin, Poland. It was established in 1941 and primarily used for the imprisonment and extermination of Jews, Polish political prisoners, and other groups deemed undesirable by the Nazi regime. The camp was liberated by the Soviet Army in July 1944, revealing the horrific conditions and mass graves. The camp's layout included barracks, gas chambers, and crematoria, reflecting its dual purpose of forced labor and mass murder. Today, Majdanek serves as a memorial and museum, educating visitors about the atrocities committed during the Holocaust and honoring the victims.
