In the 1930s the Nazi Party came to power in Germany. It imposed discrimination against Jews, with increasing restrictions and violence such as Kristallnacht in 1938, when businesses and synagogues were destroyed. It deported Jews to concentration and death camps. The Mittelbau-Dora Nazi concentration camp, established in 1943 after the destruction of Peenemünde, was located on the outskirts of Nordhausen during World War II to provide labor for the Mittelwerk V-2 rocket factory in the Kohnstein. Over its period of operation, around 60,000 inmates passed through Dora and its system of subcamps, of whom around 20,000 died from bad working conditions, starvation, and diseases, or were murdered. Around 10,000 forced labourers were deployed in several factories within the city; up to 6,000 of them were interned at Boelcke Kaserne, working for a Junkers factory.
