The estimated range of deaths often provided by historians varies quite a bit. For example, some would argue that the number of deaths due to the forced collectivization and the Great Purge could range from 6 to 9 million people. Some researchers suggest that around 12 million Christians died in religious repression under the Soviet Union. The total fatalities in the USSR, owing to policies and actions that targeted religious groups, others suggest, may have mounted to 20 million, reflecting the higher end of the estimates.
