In the early decades after the Russian Revolution, the Bolsheviks struggled to establish atheism in the Soviet Union. While some believed religion would fade as socialist reforms took hold, people continued practicing their faith. In the late 1920s, the government established "Museums of Atheism" housed in former churches and monasteries to promote scientific atheism and expose the "crimes" of religion. These museums grew in popularity and by the late 1980s some had wait times of two hours to enter. After the Soviet collapse in the early 1990s, most Museums of Atheism closed, with some rebranding as Museums of Religion.
