That’s the topic of my weekend column at RealClearHistory. An excerpt:
4. Buddhism was also outlawed and persecuted to the fullest extent of the Soviet law. Buddhism was practiced by a few different non-Russian ethnic groups in central Asia, and these small ethnic groups were given more leniency than most, but Buddhism came to be viewed by the Soviet intelligentsia as extremely dangerous, due to the fact that many left-leaning scholars abandoned socialism for Buddhist principles. The work of Andrei Znamenski, a historian of religion and ideology at the University of Memphis, is particularly useful for finding out why this happened.
