I know there was one in the USSR in 1932 and one in the PRC in 1958. I know that they’re a major talking point of the “communism killed 100 million people” myth. I’d like to be able to understand them better and extract valid criticisms out of them so I don’t end up looking ignorant or sycophantic while trying to explain why I support communist countries.
In both cases there were serious droughts and I’ve heard that in China it was a terrible flood year for the Yangtze but I haven’t looked in to it in detail.
