Buchenwald Concentration Camp

Buchenwald was a Nazi concentration camp established on Ettersberg hill near Weimar, Germany, in July 1937. It was one of the first and the largest of the concentration camps within Germany's 1937 borders. Many actual or suspected communists were among the first internees. Prisoners came from all over Europe and the Soviet Union—Jews, Poles and other Slavs, the mentally ill and physically disabled, political prisoners, Romani people, Freemasons, and prisoners of war.
