The passage of time occupied a central place in Nazi and Soviet concentration camps. Time affected everyone and everything, from the revolutionary States of Nazi Germany and Soviet Russia, to the guards who kept watch over their camps, and the inmates incarcerated in them. The State, under the guise of a revolution for utopia, manipulated time, attempting to accelerate it. The States ultimately had different visions of utopia. The Nazi State saw time leading to a cleansing of the social body and the destruction of a “cancerous growth” allegedly ruining the State. The Soviet State believed time would lead to the building of a socialist paradise and the redemption of those afflicted by the ills of capitalism. The striving by both States for an era of perfection reflected a certain ‘end-time’ mentality that informed the structuring of time in the camps.
