Following Karl Marx's idea of religion being 'the opium of the people', the USSR became the first state to have the elimination of religion as an ideological objective.
Scientific atheism was proclaimed the official policy, enforced by the state and encouraged by anti-religious propaganda.
We've collected some particularly interesting exhibits below...
