Dachau Concentration Camp was the first Nazi concentration camp, established in 1933 near Dachau, Germany. Initially designed to hold political prisoners, it later expanded to include various groups, including Jews, Roma, and homosexuals. The camp served as a model for other concentration camps and was a site of forced labor, medical experiments, and brutal treatment. The camp was liberated by American forces on April 29, 1945. After the war, it became a memorial site to honor the victims and educate the public about the atrocities committed during the Holocaust. Today, the Dachau Memorial Site serves as a reminder of the dangers of hatred and intolerance.
