 Similar references could be offered concerning Stalin’s war on the kulaks in the Ukraine (1930s), mass starvation in China (1958–61), the widespread violence of the Cultural Revolution in China (1966–1976), and the use of violence in the American South to enforce Jim Crow-era race relations (1930s–1960s). In each case terrible things took place on a wide scale, and barriers exist that make it difficult for historians and the public to come to know the details of these periods.
