The first Nazi concentration camp was opened in Nohra to reduce overcrowding in prisons from the arrest of German Communists.

Nohra was the first of the early Nazi concentration camps in Germany, established 3 March 1933 in a school at an airfield in Nohra. The camp was administered by the interior ministry of Thuringia. The inmates were exclusively communists and included half of the Communist party group in the Thuringian state parliament. Prisoners were not forced to work or systematically abused, but had to suffer from poor hygienic conditions and did not have beds. The camp was closed down again after a few months, and the building was demolished in the 1950s. A plaque commemorating the camp was installed in 1988 but taken down in 1990; as of 2023 there is no memorial board for the camp.

Nohra is a village and a former municipality in the Weimarer Land district of Thuringia, Germany. On 1 December 2007, the municipality of Utzberg was incorporated into Nohra. Nohra later became part of Grammetal municipality in December 2019.

The Communist Party of Germany was the major far-left political party in the Weimar Republic during the interwar period, an underground resistance movement in Nazi Germany, and a minor party in Allied-occupied Germany and West Germany during the post-war period until it merged with the SPD in the Soviet occupation zone in 1946 and was banned by the West German Federal Constitutional Court in 1956.
